Add comprehensive security tests for OWASP A03 (Injection) and A10 (SSRF)
- Implemented InjectionTests.cs to cover various injection vulnerabilities including SQL, NoSQL, Command, LDAP, and XPath injections. - Created SsrfTests.cs to test for Server-Side Request Forgery (SSRF) vulnerabilities, including internal URL access, cloud metadata access, and URL allowlist bypass attempts. - Introduced MaliciousPayloads.cs to store a collection of malicious payloads for testing various security vulnerabilities. - Added SecurityAssertions.cs for common security-specific assertion helpers. - Established SecurityTestBase.cs as a base class for security tests, providing common infrastructure and mocking utilities. - Configured the test project StellaOps.Security.Tests.csproj with necessary dependencies for testing.

# SCA Failure Catalogue Fixtures (Placeholder)
|
||||
# SCA Failure Catalogue Fixtures
|
||||
|
||||
This directory hosts deterministic fixtures for the five regressions in
|
||||
`docs/product-advisories/29-Nov-2025 - SCA Failure Catalogue for StellaOps Tests.md`.
|
||||
This directory hosts deterministic fixtures for scanner failure mode regression testing.
|
||||
Each fixture documents a real-world failure pattern that StellaOps must handle correctly.
|
||||
|
||||
Cases (to be populated):
|
||||
- FC1 credential leak (Grype)
|
||||
- FC2 Trivy offline DB schema mismatch
|
||||
- FC3 SBOM parity drift
|
||||
- FC4 Grype version divergence
|
||||
- FC5 inconsistent detection
|
||||
## Catalogue Overview
|
||||
|
||||
| ID | Name | Failure Mode | Added |
|
||||
|----|------|--------------|-------|
|
||||
| FC1 | Credential Leak | Grype credential leak in environment | 2025-11-30 |
|
||||
| FC2 | Trivy DB Schema | Trivy offline DB schema mismatch | 2025-11-30 |
|
||||
| FC3 | SBOM Parity | SBOM parity drift between tools | 2025-11-30 |
|
||||
| FC4 | Grype Version | Grype version divergence | 2025-11-30 |
|
||||
| FC5 | Inconsistent Detection | Inconsistent detection across runs | 2025-11-30 |
|
||||
| FC6 | Java Shadow JAR | Fat/uber JARs with shaded dependencies | 2025-12-16 |
|
||||
| FC7 | .NET Transitive Pinning | Transitive dependency version conflicts | 2025-12-16 |
|
||||
| FC8 | Docker Multi-Stage Leakage | Build-time deps leaking into runtime | 2025-12-16 |
|
||||
| FC9 | PURL Namespace Collision | Same package name in different ecosystems | 2025-12-16 |
|
||||
| FC10 | CVE Split/Merge | CVE split/merge tracking issues | 2025-12-16 |
|
||||
|
||||
## Fixture Structure
|
||||
|
||||
Each fixture directory (`fc1/`, `fc2/`, etc.) contains:
|
||||
|
||||
- `expected.json` - Expected scanner output and test assertions
|
||||
- `input.txt` - Input description and configuration
|
||||
- `manifest.dsse.json` - DSSE-signed manifest for integrity verification
|
||||
|
||||
## Usage
|
||||
|
||||
```bash
|
||||
# Run all catalogue tests
|
||||
dotnet test --filter "Category=ScaCatalogue"
|
||||
|
||||
# Run specific fixture
|
||||
dotnet test --filter "FullyQualifiedName~FC6"
|
||||
```
|
||||
|
||||
## Constraints
|
||||
|
||||
- All fixtures are deterministic and offline-capable
|
||||
- Pinned tool versions and feeds are recorded in `inputs.lock`
|
||||
- No network access; rely on bundled caches only
|
||||
- All outputs must be normalized before comparison
|
||||
|
||||
- Pinned tool versions and feeds are recorded in `inputs.lock`.
|
||||
- Each case will include DSSE-signed manifests and normalized expected outputs.
|
||||
- No network access; rely on bundled caches only.

# Security Testing Framework
|
||||
|

This directory contains systematic security tests covering OWASP Top 10 vulnerabilities for StellaOps modules.

## OWASP Top 10 Coverage
|
||||
|
||||
| Rank | Category | Priority | Status |
|
||||
|------|----------|----------|--------|
|
||||
| A01 | Broken Access Control | CRITICAL | ✓ |
|
||||
| A02 | Cryptographic Failures | CRITICAL | ✓ |
|
||||
| A03 | Injection | CRITICAL | ✓ |
|
||||
| A05 | Security Misconfiguration | HIGH | ✓ |
|
||||
| A07 | Authentication Failures | CRITICAL | ✓ |
|
||||
| A08 | Integrity Failures | HIGH | ✓ |
|
||||
| A10 | SSRF | HIGH | ✓ |
|
||||
|
||||
## Running Tests
|
||||
|
||||
```bash
|
||||
# Run all security tests
|
||||
dotnet test tests/security/StellaOps.Security.Tests --filter "Category=Security"
|
||||
|
||||
# Run specific OWASP category
|
||||
dotnet test --filter "FullyQualifiedName~A01_BrokenAccessControl"
|
||||
|
||||
# Run with detailed output
|
||||
dotnet test tests/security/StellaOps.Security.Tests -v normal
|
||||
```
|
||||
|
||||
## Adding New Tests
|
||||
|
||||
1. Create test class in appropriate category directory
|
||||
2. Inherit from `SecurityTestBase`
|
||||
3. Use `MaliciousPayloads` for injection payloads
|
||||
4. Use `SecurityAssertions` for security-specific assertions
|
||||
|
||||
## CI Integration
|
||||
|
||||
Security tests run as part of the CI pipeline:
|
||||
- All PRs: Run critical security tests (A01, A02, A03, A07)
|
||||
- Nightly: Full OWASP Top 10 coverage
|
||||
- Pre-release: Full suite with extended fuzzing
