Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL
|
||||||
|
to crash leading to a potential Denial of Service attack.
|
||||||
|
|
||||||
|
The PKCS12 specification allows certain fields to be NULL, but OpenSSL does
|
||||||
|
not correctly check for this case. A NULL value can lead to a memory access
|
||||||
|
violation when processing PKCS12 files.

# SPRINT INDEX: Golden-Set Diff Layer - Proof-of-Fix Verification
|
||||||
|
|
||||||
|
> **Epic:** Binary-Level Patch Verification with Attestable Evidence
|
||||||
|
> **Batch:** 012
|
||||||
|
> **Status:** DONE (10 of 10 sprints DONE)
|
||||||
|
> **Created:** 10-Jan-2026
|
||||||
|
> **Source Advisory:** `docs/product/advisories/10-Jan-2026 - Golden-Set Diff Layer.md`

|
||||||
|
|
||||||
|
## Executive Summary
|
||||||
|
|
||||||
|
This sprint batch implements a **proof-of-fix verification system** that proves patches eliminate vulnerable code paths - not by version matching, but by demonstrating the actual vulnerable function/edge is gone. This creates **defensible, auditable evidence** that a CVE is truly fixed.
|
||||||
|
|
||||||
|
### The Problem
|
||||||
|
|
||||||
|
Version strings lie:
|
||||||
|
- Distros backport fixes without changing upstream version
|
||||||
|
- Vendors hot-patch binaries without metadata updates
|
||||||
|
- SBOMs rarely prove the *specific vulnerable path* is gone
|
||||||
|
- Traditional scanners say "vulnerable" when the code is actually patched
|
||||||
|
|
||||||
|
### The Solution: Golden-Set Diff Layer
|
||||||
|
|
||||||
|
```
|
||||||
|
Golden Set (truth seeds) → Binary Fingerprints → Reachability Analysis → Diff Engine → FixChain Attestation
|
||||||
|
```
|
||||||
|
|
||||||
|
**Key insight:** We already have ~70% of this in BinaryIndex. This sprint formalizes the "golden set" concept and creates auditable attestations.
|
||||||
|
|
||||||
|
### Business Value
|
||||||
|
|
||||||
|
| Benefit | Impact |
|
||||||
|
|---------|--------|
|
||||||
|
| **Backport detection** | Recognize fixes even when version "looks" unfixed |
|
||||||
|
| **Air-gap compatible** | Everything reproducible from local inputs |
|
||||||
|
| **Objective verdicts** | Concrete graph/taint deltas, not CVSS chatter |
|
||||||
|
| **Release gating** | Promotion only if `fixchain.verdict == fixed` |
|
||||||
|
| **Audit-ready** | Full chain of custody for compliance |

## Integration Points
|
||||||
|
|
||||||
|
### Risk Engine Integration (012_007)
|
||||||
|
|
||||||
|
**FixChainRiskProvider adjusts risk based on fix verification:**
|
||||||
|
|
||||||
|
| Verification Status | Risk Adjustment |
|
||||||
|
|--------------------|-----------------|
|
||||||
|
| `fixed` (confidence ≥0.95) | -80% (near elimination) |
|
||||||
|
| `fixed` (confidence 0.8-0.95) | -60% |
|
||||||
|
| `fixed` (confidence 0.6-0.8) | -40% |
|
||||||
|
| `inconclusive` | No change (conservative) |
|
||||||
|
| `still_vulnerable` | No change |
|
||||||
|
| No FixChain attestation | No change |
|
||||||
|
|
||||||
|
**Risk factor in verdict:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"riskFactors": [
|
||||||
|
{
|
||||||
|
"type": "fixChainVerification",
|
||||||
|
"status": "fixed",
|
||||||
|
"confidence": 0.97,
|
||||||
|
"adjustment": -0.80,
|
||||||
|
"evidence": "fixchain://sha256:abc123..."
|
||||||
|
}
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Policy Engine Integration (012_008)
|
||||||
|
|
||||||
|
**FixChainGate predicate for release promotion:**
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Policy: Require fix verification for critical CVEs
|
||||||
|
gates:
|
||||||
|
- name: "fix-chain-critical"
|
||||||
|
predicate: "fixChainRequired"
|
||||||
|
parameters:
|
||||||
|
severities: ["critical", "high"]
|
||||||
|
minConfidence: 0.85
|
||||||
|
allowInconclusive: false
|
||||||
|
action: "block"
|
||||||
|
message: "Critical CVE requires verified fix before release"
|
||||||
|
```
|
||||||
|
|
||||||
|
**K4 lattice integration:**
|
||||||
|
```
|
||||||
|
FixChainVerified ⊓ ReachabilityConfirmed → ReleaseAllowed
|
||||||
|
FixChainInconclusive ⊓ Critical → ManualReviewRequired
|
||||||
|
FixChainMissing ⊓ Critical → ReleaseBlocked
|
||||||
|
```
|
||||||
|
|
||||||
|
### Frontend Integration (012_009)
|
||||||
|
|
||||||
|
**Fix Verification Panel in VulnExplorer:**

## Objective
|
||||||
|
|
||||||
|
Create a streamlined workflow for authoring golden sets, combining automated extraction from advisories with AI-assisted enrichment and human curation.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| Manual golden set creation | Automated draft generation |
|
||||||
|
| No guidance on targets | AI-suggested functions/edges |
|
||||||
|
| Time-consuming curation | Assisted enrichment |
|
||||||
|
| No review workflow | Structured approval process |

## Decisions & Risks
|
||||||
|
|
||||||
|
| Decision/Risk | Notes |
|
||||||
|
|---------------|-------|
|
||||||
|
| AI for enrichment only | Human curation still required |
|
||||||
|
| Confidence thresholds | Start conservative (>0.8 for auto-accept) |
|
||||||
|
| Review required | All golden sets need human approval |
|
||||||
|
| Upstream commit access | May fail for private repos |

|
|

|
## Objective
|
||||||
|
|
||||||
|
Create the `fix-chain/v1` attestation predicate that provides cryptographically verifiable proof that a patch eliminates a vulnerable code path.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| No attestable fix evidence | DSSE-signed fix proofs |
|
||||||
|
| Trust vendor claims | Verify with evidence chain |
|
||||||
|
| No air-gap verification | Offline-verifiable bundles |
|
||||||
|
| Ad-hoc fix tracking | Formal predicate schema |
|
||||||
|

# Sprint SPRINT_20260110_012_007_RISK - Risk Engine Fix Verification Integration
|

|
|
||||||
|
> **Parent:** [SPRINT_20260110_012_000_INDEX](./SPRINT_20260110_012_000_INDEX_golden_set_diff_layer.md)
|
||||||
|
> **Status:** DONE
|
||||||
|
> **Created:** 10-Jan-2026
|
||||||
|
> **Module:** RISK (RiskEngine)
|

|

|
## Objective
|
||||||
|
|
||||||
|
Integrate FixChain attestation verdicts into the Risk Engine, enabling automatic risk score adjustment based on verified fix status.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| Risk scores ignore fix verification | Fix confidence reduces risk |
|
||||||
|
| Binary matches = always vulnerable | Verified fixes lower severity |
|
||||||
|
| No credit for patched backports | Backport fixes recognized |
|
||||||
|
| Manual risk exceptions needed | Automatic risk adjustment |

## Risk Adjustment Model
|
||||||
|
|
||||||
|
### FixChain Verdict → Risk Modifier
|
||||||
|
|
||||||
|
| Verdict | Confidence | Risk Modifier | Rationale |
|
||||||
|
|---------|------------|---------------|-----------|
|
||||||
|
| `fixed` | ≥0.95 | -80% | High-confidence verified fix |
|
||||||
|
| `fixed` | 0.85-0.95 | -60% | Verified fix, some uncertainty |
|
||||||
|
| `fixed` | 0.70-0.85 | -40% | Likely fixed, needs confirmation |
|
||||||
|
| `fixed` | <0.70 | -20% | Possible fix, low confidence |
|
||||||
|
| `inconclusive` | any | 0% | Cannot determine, conservative |
|
||||||
|
| `still_vulnerable` | any | 0% | No fix detected |
|
||||||
|
| No attestation | N/A | 0% | No verification performed |
|
||||||
|
|
||||||
|
### Modifier Formula
|
||||||
|
|
||||||
|
```
|
||||||
|
AdjustedRisk = BaseRisk × (1 - (Modifier × ConfidenceWeight))
|

## Decisions & Risks
|
||||||
|
|
||||||
|
| Decision/Risk | Notes |
|
||||||
|
|---------------|-------|
|
||||||
|
| Conservative thresholds | Start high, can lower based on accuracy |
|
||||||
|
| No automatic upgrade | Inconclusive doesn't increase risk |
|
||||||
|
| Cache TTL | 30 minutes balances freshness vs. performance |
|
||||||
|
| Attestation required | No reduction without verifiable evidence |

## Objective
|
||||||
|
|
||||||
|
Create policy predicates that gate release promotion and deployment based on fix verification status, ensuring critical vulnerabilities have verified fixes before production.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| Manual fix verification | Automated policy gates |
|
||||||
|
| Trust vendor fix claims | Require verification evidence |
|
||||||
|
| Inconsistent release criteria | Codified fix requirements |
|
||||||
|
| Post-deployment discovery | Pre-deployment blocking |

||||||

## Decisions & Risks
|

|
|
||||||
|
| Decision/Risk | Notes |
|
||||||
|
|---------------|-------|
|
||||||
|
| Grace period | Allows time for golden set creation |
|
||||||
|
| Confidence tiers | Configurable per policy |
|
||||||
|
| Inconclusive handling | Policy-driven, not global |
|
||||||
|
| Golden set approval | Prevents untrusted golden sets |

## Objective
|
||||||
|
|
||||||
|
Create frontend components that display fix verification status, allow users to understand why a vulnerability is considered fixed, and visualize the evidence chain.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| No visibility into fix verification | Clear verdict badges |
|
||||||
|
| Black-box risk scores | Transparent risk adjustments |
|
||||||
|
| No evidence exploration | Clickable evidence links |
|
||||||
|
| No diff visualization | Code-level change views |
|
||||||

|
|---------------|-------|
|

|
| Parallel data fetch | All 9 providers called concurrently via Task.WhenAll |
|
||||||
|
| Evidence-grounded responses | Model MUST cite evidence links; no hallucination |
|
||||||
|
| Schema-validated I/O | Both input bundle and output response validated against JSON Schema |
|
||||||
|
| Existing service integration | Providers wrap existing Stella service clients |
|
||||||
|
| Action policy gating | Waive/propose-fix actions require policy approval |

## Objective
|
||||||
|
|
||||||
|
Implement the four core data providers that supply the most critical evidence for vulnerability analysis: VEX verdicts, SBOM component data, reachability analysis, and binary patch detection.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| Provider interfaces defined | Full implementations |
|
||||||
|
| No VEX integration | VexLens consensus verdicts in bundles |
|
||||||
|
| No SBOM integration | Component details from SbomService |
|
||||||
|
| No reachability data | Call graph paths from ReachGraph |
|
||||||
|
| No binary patch data | Backport evidence from BinaryIndex |
|
||||||

## Decisions & Risks
|
||||||
|
|
||||||
|
| Decision/Risk | Notes |
|
||||||
|
|---------------|-------|
|
||||||
|
| Graceful degradation | Providers return empty results on failure, don't fail entire bundle |
|
||||||
|
| Parallel fetch | All providers called concurrently to minimize latency |
|
||||||
|
| Path limit (5) | Prevents context explosion while providing representative paths |
|
||||||
|
| Evidence link IDs | All results include IDs for [evidence:type:id] links |

## Objective
|
||||||
|
|
||||||
|
Implement the five contextual data providers that enrich the evidence bundle with operational memory, policy context, provenance attestations, fix recommendations, and environmental context.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| Provider interfaces defined | Full implementations |
|
||||||
|
| No conversation memory | OpsMemory integration for context |
|
||||||
|
| No policy context | Policy gate integration |
|
||||||
|
| No attestation data | Provenance/DSSE attestations |
|
||||||
|
| No fix suggestions | Integration with Concelier/NVD fixes |
|
||||||
|
| No environment context | Deployment/runtime context |
|
||||||

## Decisions & Risks
|
||||||
|
|
||||||
|
| Decision/Risk | Notes |
|
||||||
|
|---------------|-------|
|
||||||
|
| OpsMemory optional | Chat works without OpsMemory (new conversations) |
|
||||||
|
| Policy pre-evaluation | Avoids surprise rejections in response |
|
||||||
|
| NVD integration | Supplements Concelier with vendor patches |
|
||||||
|
| Environment tier inference | Fallback when explicit environment not provided |

## Objective
|
||||||
|
|
||||||
|
Comprehensive testing and hardening of the Advisory Chat feature: end-to-end tests with real services, performance testing, security validation, determinism verification, and documentation.
|
||||||
|
|
||||||
|
### Why This Matters
|
||||||
|
|
||||||
|
| Current State | Target State |
|
||||||
|
|---------------|--------------|
|
||||||
|
| Unit + integration tests | Full E2E test coverage |
|
||||||
|
| No performance baseline | Latency and throughput benchmarks |
|
||||||
|
| No security validation | Input sanitization, PII detection tested |
|
||||||
|
| No determinism tests | Reproducible bundle IDs verified |
|
||||||
|
| Partial documentation | Complete API and usage docs |
|
||||||

# Advisory AI Chat
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Advisory AI Chat is an evidence-grounded AI assistant that explains scanner findings
|
||||||
|
in plain language with actionable mitigations. All responses are backed by verifiable
|
||||||
|
evidence from Stella's structured data.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- **Slash Commands**: `/explain`, `/is-it-reachable`, `/propose-fix`, `/waive`, `/batch-triage`, `/compare`
|
||||||
|
- **Natural Language**: Infers intent from conversational queries
|
||||||
|
- **Evidence Grounding**: Every claim links to SBOM, VEX, reachability, or binary patch evidence
|
||||||
|
- **Policy Integration**: Actions gated by K4 lattice policy evaluation
|
||||||
|
- **Conversation Memory**: Continues context across turns via OpsMemory
|
||||||
|
|
||||||
|
## Architecture
|
||||||
|
|
||||||
|
[Include ASCII diagram from index sprint]
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
AdvisoryAI:
|
||||||
|
Chat:
|
||||||
|
Enabled: true
|
||||||
|
Inference:
|
||||||

# ... full config options
|
||||||
|
```
|
||||||
|
|
||||||
|
## API Reference
|
||||||
|
|
||||||
|
### POST /api/advisory/chat
|
||||||
|
|
||||||
|
Start a new conversation or query in a new context.
|
||||||
|
|
||||||
|
**Request:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"query": "/explain CVE-2024-12345 in payments@sha256:abc123 prod",
|
||||||
|
"artifactDigest": "sha256:abc123...",
|
||||||
|
"findingId": "CVE-2024-12345",
|
||||||
|
"environment": "prod"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Response:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"conversationId": "conv-abc123",
|
||||||
|
"response": {
|
||||||
|
"summary": "CVE-2024-12345 affects openssl...",
|
||||||
|
"impactAssessment": "...",
|
||||||
|
"reachabilityAssessment": "...",
|
||||||
|
"mitigations": [...],
|
||||||
|
"evidenceLinks": [...]
|
||||||
|
},
|
||||||
|
"bundleId": "bundle-abc123",
|
||||||
|
"processedAt": "2026-01-10T12:00:00Z"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Evidence Link Format
|
||||||
|
|
||||||
|
| Type | Format | Example |
|
||||||
|
|------|--------|---------|
|
||||||
|
| SBOM | `[sbom:{digest}:{purl}]` | `[sbom:sha256:abc:pkg:npm/lodash@4.17.21]` |
|
||||||
|
| VEX | `[vex:{provider}:{obsId}]` | `[vex:vendor-a:obs-123]` |
|
||||||
|
| Reachability | `[reach:{witnessId}]` | `[reach:path-456]` |
|
||||||
|
| Binary Patch | `[binpatch:{proofId}]` | `[binpatch:proof-789]` |
|
||||||
|
|
||||||
|
## Security
|
||||||
|
|
||||||
|
- PII detection blocks sensitive data
|
||||||
|
- Prompt injection mitigations
|
||||||
|
- Query length limits
|
||||||
|
- Authorization required (AdvisoryChat policy)
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
| Metric | Target |
|
||||||
|
|--------|--------|
|
||||||
|
| Evidence assembly | < 100ms P50 |
|
||||||
|
| Full query (no inference) | < 150ms P50 |
|
||||||
|
| With inference | < 2s P50 |
|
||||||
|
```
|
||||||
|
|
||||||
|
**OpenAPI Spec (`docs/api/advisory-chat.yaml`):**
|
||||||
|
- Full OpenAPI 3.0 specification for all endpoints
|
||||||
|
- Request/response schemas
|
||||||
|
- Error responses
|
||||||
|
- Authentication requirements
|
||||||
|
|
||||||
|

## Decisions & Risks
|
||||||
|
|
||||||
|
| Decision/Risk | Notes |
|
||||||
|
|---------------|-------|
|
||||||
|
| Mock inference in E2E | Real LLM calls too slow/expensive for CI |
|
||||||
|
| Testcontainers for E2E | Ensures real database behavior |
|
||||||
|
| k6 for load testing | Standard tool, CI-friendly |
|
||||||
|
| Security tests as separate category | Can run focused security scans |

# FixChain Attestation Predicate
|
||||||
|
|
||||||
|
> **Sprint:** SPRINT_20260110_012_005_ATTESTOR
|
||||||
|
> **Predicate Type:** `https://stella-ops.org/predicates/fix-chain/v1`
|
||||||
|
> **Last Updated:** 10-Jan-2026
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The FixChain predicate provides cryptographically verifiable proof that a patch eliminates a vulnerable code path. It bridges the gap between vulnerability disclosure and fix verification by encoding evidence from binary analysis into a DSSE-signed attestation.
|
||||||
|
|
||||||
|
## Why FixChain?
|
||||||
|
|
||||||
|
| Current State | With FixChain |
|
||||||
|
|---------------|---------------|
|
||||||
|
| Trust vendor claims | Verify with evidence chain |
|
||||||
|
| No attestable fix evidence | DSSE-signed fix proofs |
|
||||||
|
| Version-based assumptions | Binary signature comparison |
|
||||||
|
| No air-gap verification | Offline-verifiable bundles |
|
||||||
|
|
||||||
|

## Evidence Chain
|
||||||
|
|
||||||

## Verdict Calculation
|
||||||
|
|
||||||
|
The verdict is calculated based on multiple factors:
|
||||||
|
|
||||||
|
### Status Values
|
||||||
|
|
||||||
|
| Status | Description | Conditions |
|
||||||
|
|--------|-------------|------------|
|
||||||
|
| `fixed` | Vulnerability fully addressed | High confidence (>=80%), all paths eliminated |
|
||||||
|
| `partial` | Vulnerability partially addressed | Medium confidence (50-80%), some paths remain |
|
||||||
|
| `not_fixed` | Vulnerability still present | Diff shows no fix, paths unchanged |
|
||||||
|
| `inconclusive` | Cannot determine | Low confidence, insufficient evidence |
|
||||||
|
|
||||||
|
### Confidence Scoring
|
||||||
|
|
||||||
|
```
|
||||||
|
Confidence = Base + FunctionBonus + EdgeBonus + PathBonus
|
||||||
|
|
||||||
|
Base = Diff.Confidence (from analysis)
|
||||||
|
|
||||||
|
FunctionBonus:
|
||||||
|
- +0.1 per vulnerable function removed
|
||||||
|
- +0.05 per vulnerable function modified
|
||||||
|
|
||||||
|
EdgeBonus:
|
||||||
|
- +0.05 per vulnerable edge eliminated
|
||||||
|
|
||||||
|
PathBonus:
|
||||||
|
- +0.3 if all paths eliminated
|
||||||
|
- +0.1 if paths reduced by >50%
|
||||||
|
```
|
||||||
|
|
||||||
|
### Rationale Generation
|
||||||
|
|
||||||
|
The rationale array explains the verdict:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"rationale": [
|
||||||
|
"3 vulnerable function(s) removed",
|
||||||
|
"5 vulnerable edge(s) eliminated",
|
||||||
|
"All paths to vulnerable sink eliminated"
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||

## API Integration
|
||||||
|
|
||||||
|
### Service Registration
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
services.AddFixChainAttestation(opts =>
|
||||||
|
{
|
||||||
|
opts.AnalyzerName = "MyAnalyzer";
|
||||||
|
opts.AnalyzerVersion = "1.0.0";
|
||||||
|
opts.FixedConfidenceThreshold = 0.80m;
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Creating Attestation
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var request = new FixChainBuildRequest
|
||||||
|
{
|
||||||
|
CveId = "CVE-2024-0727",
|
||||||
|
Component = "openssl",
|
||||||
|
GoldenSetDigest = goldenSetDigest,
|
||||||
|
SbomDigest = sbomDigest,
|
||||||
|
VulnerableBinary = new BinaryIdentity { ... },
|
||||||
|
PatchedBinary = new BinaryIdentity { ... },
|
||||||
|
ComponentPurl = "pkg:deb/debian/openssl@3.1.0",
|
||||||
|
DiffResult = diffResult
|
||||||
|
};
|
||||||
|
|
||||||
|
var result = await attestationService.CreateAsync(request);
|
||||||
|
// result.EnvelopeJson - DSSE envelope
|
||||||
|
// result.ContentDigest - SHA-256 of statement
|
||||||
|
// result.Predicate - Parsed predicate
|
||||||
|
```
|
||||||
|
|
||||||
|
### Verifying Attestation
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var result = await attestationService.VerifyAsync(envelopeJson);
|
||||||
|
if (result.IsValid)
|
||||||
|
{
|
||||||
|
var verdict = result.Predicate!.Verdict;
|
||||||
|
Console.WriteLine($"Status: {verdict.Status}");
|
||||||
|
Console.WriteLine($"Confidence: {verdict.Confidence:P0}");
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Air-Gap Verification
|
||||||
|
|
||||||
|
FixChain attestations support offline verification:
|
||||||
|
|
||||||
|
1. **Bundle Export**: Export attestation with all referenced artifacts
|
||||||
|
2. **Signature Verification**: Verify DSSE signature with bundled public key
|
||||||
|
3. **Content Validation**: Validate predicate structure and content
|
||||||
|
4. **Optional Rekor Proof**: Include offline Rekor inclusion proof
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Export bundle for air-gap
|
||||||
|
stella attest bundle export \
|
||||||
|
--attestation fixchain.dsse.json \
|
||||||
|
--include-artifacts \
|
||||||
|
--out fixchain-bundle.tar.gz
|
||||||
|
|
||||||
|
# Verify in air-gap
|
||||||
|
stella attest bundle verify \
|
||||||
|
--bundle fixchain-bundle.tar.gz \
|
||||||
|
--offline
|
||||||
|
```

# Golden Set Schema Documentation
|
||||||
|
|
||||||

> **Version:** 1.0.0
|
||||||
|
> **Module:** BinaryIndex.GoldenSet
|

|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Golden Sets are ground-truth definitions of vulnerability code-level manifestations. They capture the specific functions, basic block edges, sinks, and constants that characterize a vulnerability, enabling:
|
||||||
|
|
||||||
|
- **Deterministic vulnerability detection** via fingerprint matching
|
||||||
|
- **Backport verification** through pre/post patch comparison
|
||||||
|
- **Audit trail** for security claims with content-addressed provenance
|
||||||
|
|
||||||
|
## YAML Schema
|
||||||
|
|
||||||
|
Golden sets are stored as human-readable YAML files for git-friendliness and easy review.
|
||||||
|

|
}
|

|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Edge Format
|
||||||
|
|
||||||
|
Basic block edges follow the format `bbN->bbM` where:
|
||||||
|
- `bbN` is the source basic block identifier
|
||||||
|
- `bbM` is the target basic block identifier
|
||||||
|
- The `->` separator indicates control flow direction
|
||||||
|
|
||||||
|
Examples:
|
||||||
|
- `bb3->bb7` - Control flows from block 3 to block 7
|
||||||
|
- `bb7->bb9` - Control flows from block 7 to block 9
|
||||||
|
- `bb1->bb3` - Control flows from block 1 to block 3
|
||||||
|
|
||||||
|
Edge identifiers match common disassembler output (IDA, Ghidra, Binary Ninja).
|
||||||
|
|
||||||
|
## Sink Registry
|
||||||
|
|
||||||
|
Known sinks are validated against the sink registry. Categories include:
|
||||||
|
|
||||||
|
| Category | Examples | CWEs |
|
||||||
|
|----------|----------|------|
|
||||||
|
| `memory` | memcpy, strcpy, free, malloc | CWE-120, CWE-787, CWE-415, CWE-416 |
|
||||||
|
| `command_injection` | system, exec, popen | CWE-78 |
|
||||||
|
| `code_injection` | dlopen, LoadLibrary | CWE-427 |
|
||||||
|
| `path_traversal` | fopen, open | CWE-22 |
|
||||||
|
| `network` | connect, send, recv | CWE-918, CWE-319 |
|
||||||
|
| `sql_injection` | sqlite3_exec, mysql_query | CWE-89 |
|
||||||
|
| `crypto` | EVP_DecryptUpdate, PKCS12_parse | CWE-327, CWE-295 |
|
||||||
|
|
||||||
|
Unknown sinks generate validation warnings but do not block acceptance.
|
||||||
|
|
||||||
|
## Content Addressing
|
||||||
|
|
||||||
|
Golden sets are content-addressed using SHA256:
|
||||||
|
|
||||||
|
1. Definition is serialized to canonical JSON (sorted keys, no whitespace)
|
||||||
|
2. SHA256 hash is computed over UTF-8 bytes
|
||||||
|
3. Digest is formatted as `sha256:<64-hex-chars>`
|
||||||
|
|
||||||
|
Example: `sha256:a1b2c3d4e5f6...`
|
||||||
|
|
||||||
|
Content addressing enables:
|
||||||
|
- Deduplication in storage
|
||||||
|
- Audit trail verification
|
||||||
|
- Immutable references in attestations
|
||||||
|
|
||||||
|
## Status Workflow
|
||||||
|
|
||||||
|
Golden sets progress through these statuses:
|
||||||
|
|
||||||
|
```
|
||||||
|
Draft → InReview → Approved
|
||||||
|
↓
|
||||||
|
Draft (if changes requested)
|
||||||
|
|
||||||
|
Approved → Deprecated (if CVE retracted)
|
||||||
|
→ Archived (for historical reference)
|
||||||
|
```
|
||||||
|
|
||||||
|
| Status | Description |
|
||||||
|
|--------|-------------|
|
||||||
|
| `Draft` | Initial creation, editable |
|
||||||
|
| `InReview` | Submitted for review |
|
||||||
|
| `Approved` | Active in corpus, used for detection |
|
||||||
|
| `Deprecated` | CVE retracted or superseded |
|
||||||
|
| `Archived` | Historical reference only |
|
||||||
|
|
||||||
|
## Best Practices
|
||||||
|
|
||||||
|
### Authoring Golden Sets
|
||||||
|
|
||||||
|
1. **Start minimal** - Begin with function name only, add edges/sinks as verified
|
||||||
|
2. **Use authoritative sources** - NVD, vendor advisories, upstream commits
|
||||||
|
3. **Document invariants** - Explain exploitation conditions in human-readable text
|
||||||
|
4. **Tag appropriately** - Use consistent classification tags
|
||||||
|
5. **Review carefully** - Treat golden sets like unit tests
|
||||||
|
|
||||||
|
### Edge Selection
|
||||||
|
|
||||||
|
1. **Focus on vulnerable paths** - Only include edges on the exploitation path
|
||||||
|
2. **Avoid over-specification** - Fewer edges = more robust matching
|
||||||
|
3. **Document rationale** - Explain why specific edges are included
|
||||||
|
|
||||||
|
### Sink Selection
|
||||||
|
|
||||||
|
1. **Use known sinks** - Prefer sinks from the registry
|
||||||
|
2. **Include all relevant sinks** - List all sinks on the vulnerable path
|
||||||
|
3. **Order consistently** - Alphabetical ordering aids diffing
|
||||||
|
|
||||||
|

# SBOM Extension Fields for FixChain Attestation
|
||||||
|
|
||||||
|
> **Sprint:** SPRINT_20260110_012_005_ATTESTOR
|
||||||
|
> **Last Updated:** 10-Jan-2026
|
||||||
|
|
||||||
|
This document describes the extension fields used to link FixChain attestations to SBOM components.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
When a FixChain attestation verifies that a patch eliminates a vulnerability, the results can be embedded in the SBOM as extension properties. This enables consumers to verify fix status directly from the SBOM without separate attestation lookup.
|
||||||
|
|
||||||
|
## CycloneDX Properties
|
||||||
|
|
||||||
|
CycloneDX 1.4+ supports custom properties on components. StellaOps uses the `stellaops:` namespace for FixChain-related properties.
|
||||||
|
|
||||||
|

### Structured Annotation Format
|
||||||
|
|
||||||
|
For machine-readable annotations, use JSON within the comment field:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"annotations": [
|
||||||
|
{
|
||||||
|
"annotationDate": "2026-01-15T12:00:00Z",
|
||||||
|
"annotationType": "OTHER",
|
||||||
|
"annotator": "Tool: StellaOps FixChain Analyzer v1.0.0",
|
||||||
|
"comment": "{\"type\":\"stellaops:fixchain\",\"cveId\":\"CVE-2024-0727\",\"verdict\":\"fixed\",\"confidence\":0.97,\"fixChainRef\":\"sha256:abc123...\",\"goldenSetRef\":\"sha256:def456...\"}"
|
||||||
|
}
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## SPDX 3.0 Extensions
|
||||||
|
|
||||||
|
SPDX 3.0 introduces external references which provide better support for attestations.
|
||||||
|
|
||||||
|
### Security External Reference
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"@type": "software_Package",
|
||||||
|
"@id": "urn:spdx:Package-openssl",
|
||||||
|
"name": "openssl",
|
||||||
|
"packageVersion": "3.1.0",
|
||||||
|
"externalRef": [
|
||||||
|
{
|
||||||
|
"@type": "ExternalRef",
|
||||||
|
"externalRefType": "securityOther",
|
||||||
|
"locator": "sha256:abc123def456789...",
|
||||||
|
"comment": "FixChain attestation for CVE-2024-0727"
|
||||||
|
}
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Verification Workflow
|
||||||
|
|
||||||
|
1. **Extract Properties**: Parse SBOM and extract `stellaops:fixChainRef` properties
|
||||||
|
2. **Fetch Attestation**: Retrieve attestation by content digest
|
||||||
|
3. **Verify Signature**: Validate DSSE envelope signature
|
||||||
|
4. **Verify Predicate**: Parse and validate FixChainPredicate
|
||||||
|
5. **Match Component**: Verify SBOM component matches attestation subject
|
||||||
|
6. **Check Verdict**: Confirm verdict meets policy requirements
|
||||||
|
|
||||||
|
## CLI Usage
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Annotate SBOM with FixChain attestation
|
||||||
|
stella sbom annotate \
|
||||||
|
--sbom sbom.cdx.json \
|
||||||
|
--fixchain attestation.dsse.json \
|
||||||
|
--output sbom-annotated.cdx.json
|
||||||
|
|
||||||
|
# Verify SBOM annotations
|
||||||
|
stella sbom verify-fixchain \
|
||||||
|
--sbom sbom-annotated.cdx.json \
|
||||||
|
--attestation-store /path/to/store
|
||||||
|
|
||||||
|
# Export fix status report
|
||||||
|
stella sbom fixchain-report \
|
||||||
|
--sbom sbom-annotated.cdx.json \
|
||||||
|
--format markdown
|
||||||
|
```

# Policy Engine FixChain Gates
|
||||||
|
|
||||||
|
> **Sprint:** SPRINT_20260110_012_008_POLICY
|
||||||
|
> **Last Updated:** 10-Jan-2026
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
FixChain gates are policy predicates that control release promotion based on verified fix status. They integrate FixChain attestations from the binary-level fix verification system into policy decisions, blocking or warning on releases that contain critical vulnerabilities without verified fixes.
|
||||||
|
|
||||||
|
## Why This Matters
|
||||||
|
|
||||||
|
| Current State | With FixChain Gates |
|
||||||
|
|---------------|---------------------|
|
||||||
|
| Manual fix verification | Automated policy gates |
|
||||||
|
| Trust vendor fix claims | Require verification evidence |
|
||||||
|
| Inconsistent release criteria | Codified fix requirements |
|
||||||
|
| Post-deployment discovery | Pre-deployment blocking |
|
||||||
|
|
||||||
|
## Configuration

|
// Inject the predicate
|
||||||
|
var predicate = services.GetRequiredService<IFixChainGatePredicate>();
|
||||||
|
|
||||||
|
// Create context for a finding
|
||||||
|
var context = new FixChainGateContext
|

};
|
||||||
|
|
||||||
|
// Configure parameters
|
||||||
|
var parameters = new FixChainGateParameters

## Metrics
|
||||||
|
|
||||||
|
The gate exposes OpenTelemetry metrics:
|
||||||
|
|
||||||
|
| Metric | Type | Description |
|
||||||
|
|--------|------|-------------|
|
||||||
|
| `policy_fixchain_gate_evaluations_total` | Counter | Total evaluations |
|
||||||
|
| `policy_fixchain_gate_passes_total` | Counter | Gate passes |
|
||||||
|
| `policy_fixchain_gate_blocks_total` | Counter | Gate blocks |
|
||||||
|
| `policy_fixchain_gate_warnings_total` | Counter | Gate warnings |
|
||||||
|
| `policy_fixchain_gate_evaluation_duration_seconds` | Histogram | Evaluation duration |
|
||||||
|
| `policy_fixchain_gate_errors_total` | Counter | Evaluation errors |
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Gate Blocking Unexpectedly
|
||||||
|
|
||||||
|
1. **Check severity configuration**: Ensure the severity matches configured severities
|
||||||
|
```bash
|
||||||
|
stella policy show --policy release-gates
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Verify attestation exists**: Check if attestation is present
|
||||||
|
```bash
|
||||||
|
stella attestor query --cve CVE-2024-XXXX --predicate fixchain
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Check confidence level**: Verify confidence meets threshold
|
||||||
|
```bash
|
||||||
|
stella scanner golden show --cve CVE-2024-XXXX --verbose
|
||||||
|
```
|
||||||
|
|
||||||
|
4. **Review golden set status**: Check if golden set is approved
|
||||||
|
```bash
|
||||||
|
stella scanner golden status --cve CVE-2024-XXXX
|
||||||
|
```
|
||||||
|
|
||||||
|
### Grace Period Issues
|
||||||
|
|
||||||
|
- Grace period starts from CVE publication date in the advisory
|
||||||
|
- If publication date is unknown, grace period doesn't apply
|
||||||
|
- Use `--grace-period-override` for manual override
|
||||||
|
|
||||||
|
### Inconclusive Verdicts
|
||||||
|
|
||||||
|
Inconclusive verdicts typically occur when:
|
||||||
|
- Binary is stripped and symbols unavailable
|
||||||
|
- Golden set incomplete or too generic
|
||||||
|
- Compiler optimizations changed code structure
|
||||||
|
|
||||||
|
Resolution:
|
||||||
|
1. Obtain debug symbols
|
||||||
|
2. Enhance golden set with more specific targets
|
||||||
|
3. Consider policy exception with justification

# Risk Engine FixChain Integration
|
||||||
|
|
||||||
|
> **Sprint:** SPRINT_20260110_012_007_RISK
|
||||||
|
> **Last Updated:** 10-Jan-2026
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The Risk Engine FixChain integration enables automatic risk score adjustment based on verified fix status from FixChain attestations. When a vulnerability has a verified fix, the risk score is reduced proportionally to the verification confidence level.
|
||||||
|
|
||||||
|
## Why This Matters
|
||||||
|
|
||||||
|
| Current State | With FixChain Integration |
|
||||||
|
|---------------|---------------------------|
|
||||||
|
| Risk scores ignore fix verification | Fix confidence reduces risk |
|
||||||
|
| Binary matches = always vulnerable | Verified fixes lower severity |
|
||||||
|
| No credit for patched backports | Backport fixes recognized |
|
||||||
|
| Manual risk exceptions needed | Automatic risk adjustment |
|
||||||
|
|
||||||
|
## Risk Adjustment Model
|
||||||
|
|
||||||
|
### Verdict to Risk Modifier Mapping
|
||||||
|
|
||||||
|
| Verdict | Confidence | Risk Modifier | Rationale |
|
||||||
|
|---------|------------|---------------|-----------|
|
||||||
|
| `fixed` | >= 95% | -80% to -90% | High-confidence verified fix |
|
||||||
|
| `fixed` | 85-95% | -60% to -80% | Verified fix, some uncertainty |
|
||||||
|
| `fixed` | 70-85% | -40% to -60% | Likely fixed, needs confirmation |
|
||||||
|
| `fixed` | 60-70% | -20% to -40% | Possible fix, low confidence |
|
||||||
|
| `fixed` | < 60% | 0% | Below threshold, no adjustment |
|
||||||
|
| `partial` | >= 60% | -25% to -50% | Partial fix applied |
|
||||||
|
| `inconclusive` | any | 0% | Cannot determine, conservative |
|
||||||
|
| `still_vulnerable` | any | 0% | No fix detected |
|
||||||
|
| No attestation | N/A | 0% | No verification performed |
|
||||||
|
|
||||||
|
### Modifier Formula
|
||||||
|
|
||||||
|
```
|
||||||
|
AdjustedRisk = BaseRisk * (1 - (Modifier * ConfidenceWeight))
|
||||||
|
|
||||||
|
Where:
|
||||||
|
Modifier = verdict-based modifier from table above
|
||||||
|
ConfidenceWeight = min(1.0, (Confidence - MinThreshold) / (1.0 - MinThreshold))
|
||||||
|
```
|
||||||
|
|
||||||
|
### Example Calculation
|
||||||
|
|
||||||
|
```
|
||||||
|
CVE-2024-0727 on pkg:deb/debian/openssl@3.0.11-1~deb12u2:
|
||||||
|
BaseRisk = 8.5 (HIGH)
|
||||||
|
FixChain Verdict = "fixed"
|
||||||
|
FixChain Confidence = 0.97
|
||||||
|
|
||||||
|
Modifier = 0.90 (high confidence tier)
|
||||||
|
ConfidenceWeight = (0.97 - 0.60) / (1.0 - 0.60) = 0.925
|
||||||
|
|
||||||
|
AdjustedRisk = 8.5 * (1 - 0.90 * 0.925) = 8.5 * 0.1675 = 1.42 (LOW)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Components
|
||||||
|
|
||||||
|
### IFixChainRiskProvider
|
||||||
|
|
||||||
|
Main interface for FixChain risk integration:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
public interface IFixChainRiskProvider
|
||||||
|
{
|
||||||
|
Task<FixVerificationStatus?> GetFixStatusAsync(
|
||||||
|
string cveId,
|
||||||
|
string binarySha256,
|
||||||
|
string? componentPurl = null,
|
||||||
|
CancellationToken ct = default);
|
||||||
|
|
||||||
|
double ComputeRiskAdjustment(FixVerificationStatus status);
|
||||||
|
|
||||||
|
FixChainRiskFactor CreateRiskFactor(FixVerificationStatus status);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### FixChainRiskProvider
|
||||||
|
|
||||||
|
Implementation that:
|
||||||
|
1. Queries the attestation store for FixChain predicates
|
||||||
|
2. Computes risk adjustment based on verdict and confidence
|
||||||
|
3. Creates structured risk factors for UI display
|
||||||
|
|
||||||
|
### IFixChainAttestationClient
|
||||||
|
|
||||||
|
Client for querying attestations:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
public interface IFixChainAttestationClient
|
||||||
|
{
|
||||||
|
Task<FixChainAttestationData?> GetFixChainAsync(
|
||||||
|
string cveId,
|
||||||
|
string binarySha256,
|
||||||
|
string? componentPurl = null,
|
||||||
|
CancellationToken ct = default);
|
||||||
|
|
||||||
|
Task<ImmutableArray<FixChainAttestationData>> GetForComponentAsync(
|
||||||
|
string componentPurl,
|
||||||
|
CancellationToken ct = default);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
```csharp
|
||||||
|
services.AddOptions<FixChainRiskOptions>()
|
||||||
|
.Bind(config.GetSection("RiskEngine:Providers:FixChain"))
|
||||||
|
.ValidateDataAnnotations()
|
||||||
|
.ValidateOnStart();
|
||||||
|
|
||||||
|
services.AddSingleton<IFixChainRiskProvider, FixChainRiskProvider>();
|
||||||
|
services.AddHttpClient<IFixChainAttestationClient, FixChainAttestationClient>();
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
### Getting Fix Status
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var provider = services.GetRequiredService<IFixChainRiskProvider>();
|
||||||
|
|
||||||
|
var status = await provider.GetFixStatusAsync(
|
||||||
|
"CVE-2024-0727",
|
||||||
|
binarySha256,
|
||||||
|
componentPurl);
|
||||||
|
|
||||||
|
if (status is not null)
|
||||||
|
{
|
||||||
|
var adjustment = provider.ComputeRiskAdjustment(status);
|
||||||
|
var adjustedRisk = baseRisk * adjustment;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Creating Risk Factors
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var status = await provider.GetFixStatusAsync(cveId, binarySha256);
|
||||||
|
if (status is not null)
|
||||||
|
{
|
||||||
|
var factor = provider.CreateRiskFactor(status);
|
||||||
|
|
||||||
|
// For UI display
|
||||||
|
var display = factor.ToDisplay();
|
||||||
|
var badge = factor.ToBadge();
|
||||||
|
var summary = factor.ToSummary();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Signal-Based Scoring
|
||||||
|
|
||||||
|
For batch processing via signals:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var signals = new Dictionary<string, double>
|
||||||
|
{
|
||||||
|
[FixChainRiskProvider.SignalFixConfidence] = 0.95,
|
||||||
|
[FixChainRiskProvider.SignalFixStatus] = FixChainRiskProvider.EncodeStatus("fixed")
|
||||||
|
};
|
||||||
|
|
||||||
|
var request = new ScoreRequest("fixchain", subject, signals);
|
||||||
|
var adjustment = await provider.ScoreAsync(request, ct);
|
||||||
|
```
|
||||||
|
|
||||||
|

|
FixChainRiskMetrics.RecordLookup(
|
||||||
|
found: true,
|
||||||
|
fromCache: false,
|
||||||
|
durationSeconds: 0.05,
|

|
||||||
|
|
||||||
|
### Display Model
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var display = factor.ToDisplay();
|
||||||
|
// display.Label = "Fix Verification"
|
||||||
|
// display.Value = "Fixed (95% confidence)"
|
||||||
|
// display.Impact = -0.80
|
||||||
|
// display.ImpactDirection = "decrease"
|
||||||
|
// display.EvidenceRef = "fixchain://sha256:..."
|
||||||
|
// display.Details = { verdict, confidence, verified_at, ... }
|
||||||
|
```
|
||||||
|
|
||||||
|
### Badge Component
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var badge = factor.ToBadge();
|
||||||
|
// badge.Status = "Fixed"
|
||||||
|
// badge.Color = "green"
|
||||||
|
// badge.Icon = "check-circle"
|
||||||
|
// badge.Confidence = 0.95m
|
||||||
|
// badge.Tooltip = "Verified fix (95% confidence)"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
### Unit Tests
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
[Fact]
|
||||||
|
public async Task FixedVerdict_HighConfidence_ReturnsLowRisk()
|
||||||
|
{
|
||||||
|
var provider = new FixChainRiskProvider(options);
|
||||||
|
var status = new FixVerificationStatus
|
||||||
|
{
|
||||||
|
Verdict = "fixed",
|
||||||
|
Confidence = 0.97m,
|
||||||
|
VerifiedAt = DateTimeOffset.UtcNow,
|
||||||
|
AttestationDigest = "sha256:test"
|
||||||
|
};
|
||||||
|
|
||||||
|
var adjustment = provider.ComputeRiskAdjustment(status);
|
||||||
|
|
||||||
|
adjustment.Should().BeLessThan(0.3);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Integration Tests
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
[Fact]
|
||||||
|
public async Task FullWorkflow_FixedVerdict_ReducesRisk()
|
||||||
|
{
|
||||||
|
var attestationClient = new InMemoryFixChainAttestationClient();
|
||||||
|
attestationClient.AddAttestation(cveId, binarySha256, attestation);
|
||||||
|
|
||||||
|
var provider = new FixChainRiskProvider(options, attestationClient, logger);
|
||||||
|
var status = await provider.GetFixStatusAsync(cveId, binarySha256);
|
||||||
|
|
||||||
|
status.Should().NotBeNull();
|
||||||
|
status!.Verdict.Should().Be("fixed");
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Decisions and Trade-offs
|
||||||
|
|
||||||
|
| Decision | Rationale |
|
||||||
|
|----------|-----------|
|
||||||
|
| Conservative thresholds | Start high, can lower based on accuracy data |
|
||||||
|
| No automatic upgrade | Inconclusive doesn't increase risk |
|
||||||
|
| Cache TTL 30 minutes | Balances freshness vs. performance |
|
||||||
|
| Attestation required | No reduction without verifiable evidence |
|
||||||
|
| Minimum confidence 60% | Below this, evidence is too weak for adjustment |

# Golden Set Authoring Guide
|
||||||
|
|
||||||
|
This document describes the authoring workflow for creating and curating Golden Sets - ground-truth definitions of vulnerability code-level manifestation facts used for binary vulnerability detection.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Golden Sets are YAML-based definitions that describe:
|
||||||
|
- **Vulnerable functions** - Entry points where vulnerabilities manifest
|
||||||
|
- **Sink functions** - Dangerous API calls that enable exploitation
|
||||||
|
- **Edge patterns** - Control flow patterns indicating vulnerability presence
|
||||||
|
- **Constants** - Magic numbers, buffer sizes, or version markers
|
||||||
|
- **Witness inputs** - Example triggers for the vulnerability
|
||||||
|
|
||||||
|

## Components
|
||||||
|
|
||||||
|
### 1. Extractors
|
||||||
|
|
||||||
|
Extractors pull vulnerability data from advisory sources:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
// Extract from NVD/OSV/GHSA
|
||||||
|
var extractor = serviceProvider.GetRequiredService<IGoldenSetExtractor>();
|
||||||
|
|
||||||
|
var result = await extractor.ExtractAsync(
|
||||||
|
"CVE-2024-1234",
|
||||||
|
"openssl",
|
||||||
|
new ExtractionOptions
|
||||||
|
{
|
||||||
|
UseAiEnrichment = true,
|
||||||
|
IncludeUpstreamCommits = true,
|
||||||
|
IncludeRelatedCves = true
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
**Supported Sources:**
|
||||||
|
- **NVD** - National Vulnerability Database
|
||||||
|
- **OSV** - Open Source Vulnerabilities
|
||||||
|
- **GHSA** - GitHub Security Advisories
|
||||||
|
|
||||||
|
### 2. Upstream Commit Analyzer
|
||||||
|
|
||||||
|
Analyzes fix commits to extract:
|
||||||
|
- Modified functions (from hunk headers)
|
||||||
|
- Added constants (hex values, buffer sizes)
|
||||||
|
- Added conditions (bounds checks, NULL checks)
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var analyzer = serviceProvider.GetRequiredService<IUpstreamCommitAnalyzer>();
|
||||||
|
|
||||||
|
// Parse commit URL
|
||||||
|
var parsed = analyzer.ParseCommitUrl("https://github.com/curl/curl/commit/abc123");
|
||||||
|
|
||||||
|
// Analyze commits
|
||||||
|
var result = await analyzer.AnalyzeAsync([
|
||||||
|
"https://github.com/curl/curl/commit/abc123",
|
||||||
|
"https://github.com/curl/curl/commit/def456"
|
||||||
|
]);
|
||||||
|
|
||||||
|
// Result contains:
|
||||||
|
// - ModifiedFunctions: ["parse_header", "validate_length"]
|
||||||
|
// - AddedConstants: ["0x1000", "sizeof(buffer)"]
|
||||||
|
// - AddedConditions: ["bounds_check", "null_check"]
|
||||||
|
```
|
||||||
|
|
||||||
|
**Supported Platforms:**
|
||||||
|
- GitHub (`github.com/owner/repo/commit/hash`)
|
||||||
|
- GitLab (`gitlab.com/owner/repo/-/commit/hash`)
|
||||||
|
- Bitbucket (`bitbucket.org/owner/repo/commits/hash`)
|
||||||
|
|
||||||
|
### 3. CWE-to-Sink Mapper
|
||||||
|
|
||||||
|
Maps CWE classifications to relevant sink functions:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
// Get sinks for buffer overflow CWEs
|
||||||
|
var sinks = CweToSinkMapper.GetSinksForCwes(["CWE-120", "CWE-122"]);
|
||||||
|
// Returns: ["memcpy", "strcpy", "sprintf", "gets", ...]
|
||||||
|
|
||||||
|
// Get all mapped CWEs
|
||||||
|
var cwes = CweToSinkMapper.GetMappedCwes();
|
||||||
|
```
|
||||||
|
|
||||||
|
**Supported CWE Categories:**
|
||||||
|
| Category | CWE IDs | Example Sinks |
|
||||||
|
|----------|---------|---------------|
|
||||||
|
| Buffer Overflow | CWE-120, CWE-121, CWE-122, CWE-787 | `memcpy`, `strcpy`, `sprintf` |
|
||||||
|
| Format String | CWE-134 | `printf`, `fprintf`, `sprintf` |
|
||||||
|
| Integer Overflow | CWE-190, CWE-191 | `malloc`, `calloc`, `realloc` |
|
||||||
|
| Use After Free | CWE-416 | `free`, `delete`, `delete[]` |
|
||||||
|
| Command Injection | CWE-78 | `system`, `popen`, `execve` |
|
||||||
|
| SQL Injection | CWE-89 | `PQexec`, `mysql_query`, `sqlite3_exec` |
|
||||||
|
| Path Traversal | CWE-22 | `fopen`, `open`, `access` |
|
||||||
|
| NULL Pointer | CWE-476 | (dereference detection) |
|
||||||
|
|
||||||
|
### 4. AI Enrichment Service
|
||||||
|
|
||||||
|
Optional AI-assisted enrichment using advisory text and commit analysis:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var enrichmentService = serviceProvider.GetRequiredService<IGoldenSetEnrichmentService>();
|
||||||
|
|
||||||
|
if (enrichmentService.IsAvailable)
|
||||||
|
{
|
||||||
|
var result = await enrichmentService.EnrichAsync(
|
||||||
|
draftGoldenSet,
|
||||||
|
new GoldenSetEnrichmentContext
|
||||||
|
{
|
||||||
|
CommitAnalysis = commitResult,
|
||||||
|
CweIds = ["CWE-787"],
|
||||||
|
AdvisoryText = "Buffer overflow in parse_header..."
|
||||||
|
});
|
||||||
|
|
||||||
|
// Result.EnrichedDraft contains improved definition
|
||||||
|
// Result.ActionsApplied describes what was added/refined
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Enrichment Actions:**
|
||||||
|
- `function_added` - New vulnerable function identified
|
||||||
|
- `sink_added` - New sink function from CWE mapping
|
||||||
|
- `constant_extracted` - Magic value from commits
|
||||||
|
- `edge_suggested` - Control flow pattern suggested
|
||||||
|
- `witness_hint_added` - Example trigger input
|
||||||
|
|
||||||
|
### 5. Review Workflow
|
||||||
|
|
||||||
|
State machine for golden set curation:
|
||||||
|
|
||||||
|
```
|
||||||
|
Draft ──> InReview ──> Approved ──> Deprecated ──> Archived
|
||||||
|
│ │ │
|
||||||
|
└───────────┴────────────┴── (can return to Draft)
|
||||||
|
```
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var reviewService = serviceProvider.GetRequiredService<IGoldenSetReviewService>();
|
||||||
|
|
||||||
|

## Service Registration
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
// Program.cs or Startup.cs
|
||||||
|
services.AddGoldenSetServices(configuration);
|
||||||
|
services.AddGoldenSetAuthoring();
|
||||||
|
services.AddGoldenSetPostgresStorage();
|
||||||
|
|
||||||
|
// Optional: Add HTTP client for commit analysis
|
||||||
|
services.AddHttpClient("upstream-commits", client =>
|
||||||
|
{
|
||||||
|
client.Timeout = TimeSpan.FromSeconds(30);
|
||||||
|
client.DefaultRequestHeaders.Add("User-Agent", "StellaOps-GoldenSet/1.0");
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
## CLI Usage
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Initialize a golden set from CVE
|
||||||
|
stella scanner golden init CVE-2024-1234 --component openssl
|
||||||
|
|
||||||
|
# With options
|
||||||
|
stella scanner golden init CVE-2024-1234 \
|
||||||
|
--component openssl \
|
||||||
|
--output ./golden-sets/CVE-2024-1234.yaml \
|
||||||
|
--no-ai \
|
||||||
|
--store
|
||||||
|
|
||||||
|
# Interactive mode for refinement
|
||||||
|
stella scanner golden init CVE-2024-1234 --interactive
|
||||||
|
|
||||||
|
# Export as JSON
|
||||||
|
stella scanner golden init CVE-2024-1234 --json
|
||||||
|
```
|
||||||
|
|
||||||
|
## Validation Rules
|
||||||
|
|
||||||
|
1. **CVE Format** - Must match `CVE-YYYY-NNNNN` or `GHSA-xxxx-xxxx-xxxx`
|
||||||
|
2. **Component Required** - Non-empty component name
|
||||||
|
3. **Targets Required** - At least one vulnerable target
|
||||||
|
4. **Sinks Validation** - Sinks must be in the sink registry
|
||||||
|
5. **Edge Format** - Must match `bbN->bbM` pattern (if strict mode)
|
||||||
|
6. **Constants Format** - Hex constants must be valid (`0x...`)
|
||||||
|
|
||||||
|
## Best Practices
|
||||||
|
|
||||||
|
1. **Start with Commit Analysis** - Fix commits are the most reliable source
|
||||||
|
2. **Use CWE Mapping** - Automatic sink suggestions based on vulnerability type
|
||||||
|
3. **Validate Locally** - Always validate before submitting for review
|
||||||
|
4. **Include Witness Data** - Example inputs help verify detection accuracy
|
||||||
|
5. **Tag Appropriately** - Use consistent tags for categorization
|
||||||
|
6. **Document Source** - Always include source_ref for traceability
|
||||||
|
|
||||||
|
## Metrics
|
||||||
|
|
||||||
|
Track authoring quality with:
|
||||||
|
- **Extraction Confidence** - Overall, per-source, per-field
|
||||||
|
- **Enrichment Actions** - What was added automatically
|
||||||
|
- **Review Iterations** - How many rounds before approval
|
||||||
|
- **Detection Rate** - How well the golden set detects known-vulnerable binaries
|
||||||
|

# Advisory AI Chat - System Prompt
|
||||||
|
|
||||||
|
You are an **Advisory AI** assistant integrated into StellaOps, a container security platform. Your role is to explain scanner findings, triage vulnerabilities, and suggest actionable mitigations grounded in structured evidence.
|
||||||
|
|
||||||
|
## Core Principles
|
||||||
|
|
||||||
|
1. **Evidence-First**: Every claim must cite evidence from the provided bundle. Never hallucinate or guess.
|
||||||
|
2. **Deterministic**: Given identical evidence, produce identical answers.
|
||||||
|
3. **Conservative**: When evidence is insufficient, say "insufficient evidence" and propose how to gather more.
|
||||||
|
4. **Actionable**: Provide concrete steps users can execute immediately.
|
||||||
|
5. **Environment-Aware**: Tailor answers to the specific artifact, environment, and org policies.
|
||||||
|
|
||||||
|

||||||
|
|
||||||
|
For every finding explanation, structure your response as:
|
||||||
|
|
||||||
|
### 1. Summary (2-3 sentences max)
|
||||||
|
Brief plain-language description of what this finding means.
|

|
## Supported Intents
|
||||||
|
|
||||||
|
### /explain {CVE|finding_id} in {image} {environment}
|
||||||
|
Provide full 5-part analysis of a specific finding.
|
||||||
|
|
||||||
|
### /is-it-reachable {CVE|component} in {image}
|
||||||
|
Focus on reachability analysis:
|
||||||
|
- Summarize call graph paths (if any)
|
||||||
|
- Check for guards, gates, or mitigations
|
||||||
|
- State confidence level with evidence
|
||||||
|
|
||||||
|
### /do-we-have-a-backport {CVE} in {component}
|
||||||
|
Check binary backport status:
|
||||||
|
- Query binary fingerprint matches
|
||||||
|
- Check distro package fix status
|
||||||
|
- Provide proof links if backport detected
|
||||||
|
|
||||||
|
### /propose-fix {CVE|finding_id}
|
||||||
|
Generate ranked fix options:
|
||||||
|
1. Package upgrade (safest, if available)
|
||||||
|
2. Distro backport acceptance (if detected)
|
||||||
|
3. Config hardening (exact settings)
|
||||||
|
4. Runtime containment (WAF, seccomp, AppArmor)
|
||||||
|
|
||||||
|
Include ready-to-execute snippets for each option.
|
||||||
|
|
||||||
|
### /waive {CVE|finding_id} for {duration} because {reason}
|
||||||
|
Generate a policy-compliant waiver:
|
||||||
|
- Validate reason against org risk appetite
|
||||||
|
- Check required approvers for risk level
|
||||||
|
- Generate waiver proposal with timer
|
||||||
|
- Link to governance policy
|
||||||
|
|
||||||
|
### /batch-triage {top_n} findings in {environment} by {priority_method}
|
||||||
|
Prioritize multiple findings:
|
||||||
|
- Sort by: exploit_pressure, sla_breach, reachability
|
||||||
|
- Group by: fix_available, component, severity
|
||||||
|
- Output: ranked table with recommended actions
|
||||||
|
|
||||||
|
### /compare {env1} vs {env2}
|
||||||
|
Compare risk posture between environments:
|
||||||
|
- Delta in findings count by severity
|
||||||
|
- New/resolved vulnerabilities
|
||||||
|
- Reachability changes
|
||||||
|
- Suggest staged rollout plan
|
||||||
|
|
||||||
|
## Guardrails
|
||||||
|
|
||||||
|
### MUST DO:
|
||||||
|
- Cite at least one evidence link per claim
|
||||||
|
- Use exact component versions from evidence
|
||||||
|
- Respect environment context (prod vs dev risk levels differ)
|
||||||
|
- Pre-check suggested actions against policy before proposing
|
||||||
|
- Format all timestamps as UTC ISO-8601
|
||||||
|
|
||||||
|
### MUST NOT:
|
||||||
|
- Claim reachability without call graph evidence
|
||||||
|
- Suggest package upgrades that break version constraints
|
||||||
|
- Recommend fixes for components not in the SBOM
|
||||||
|
- Expose raw credentials, tokens, or private keys
|
||||||
|
- Execute any action without explicit user confirmation
|
||||||
|
- Reference external CVE databases unless mirrored in evidence
|
||||||
|
|
||||||
|
### WHEN EVIDENCE IS MISSING:
|
||||||
|
Say explicitly:
|
||||||
|
> "Insufficient evidence for {claim}. To resolve, {action}:
|
||||||
|
> - Enable call graph analysis for {package}
|
||||||
|
> - Request VEX statement from {vendor}
|
||||||
|
> - Run binary fingerprint scan"
|
||||||
|
|
||||||
|
## Confidence Indicators
|
||||||
|
|
||||||
|
Use these badges in your response:
|
||||||
|
|
||||||
|
- **[HIGH CONFIDENCE]**: Multiple independent evidence sources agree
|
||||||
|
- **[MEDIUM CONFIDENCE]**: Single authoritative source or consistent vendor VEX
|
||||||
|
- **[LOW CONFIDENCE]**: Inference required, evidence gaps exist
|
||||||
|
- **[INSUFFICIENT EVIDENCE]**: Cannot make claim, need more data
|
||||||
|
|
||||||
|
## Output Constraints
|
||||||
|
|
||||||
|
- Maximum response length: 2000 tokens
|
||||||
|
- Use markdown formatting for readability
|
||||||
|
- Code blocks must specify language
|
||||||
|
- Tables for comparing multiple options
|
||||||
|
- No emojis or decorative characters
|
||||||
|
- ASCII-only output
|
||||||
|
|
||||||
|

You are an expert vulnerability advisor for the StellaOps security platform.
|
||||||
|
|
||||||
|
Your role is to analyze vulnerability findings and provide actionable, evidence-grounded recommendations.
|
||||||
|
|
||||||
|
Key principles:
|
||||||
|
1. NEVER speculate or hallucinate - only cite evidence from the provided bundle
|
||||||
|
2. Use evidence links in format [type:id] to reference sources
|
||||||
|
3. Provide clear, actionable mitigations
|
||||||
|
4. Consider reachability, binary patches, and VEX verdicts
|
||||||
|
5. Be concise but thorough
|
||||||
|
|
||||||
|
Evidence link formats:
|
||||||
|
- [sbom:{digest}:{purl}] - SBOM component reference
|
||||||
|
- [vex:{providerId}:{observationId}] - VEX observation
|
||||||
|
- [reach:{witnessId}] - Reachability path witness
|
||||||
|
- [binpatch:{proofId}] - Binary patch proof
|
||||||
|
- [policy:{evaluationId}] - Policy evaluation
|
||||||
|
|
||||||
|
Always structure your response with:
|
||||||
|
1. Summary of the finding
|
||||||
|
2. Impact assessment
|
||||||
|
3. Reachability analysis (if available)
|
||||||
|
4. Recommended mitigations with effort estimates
|
||||||
|
5. Evidence links supporting your analysis
