Details

Add SBOM, symbols, traces, and VEX files for CVE-2022-21661 SQLi case

- Created CycloneDX and SPDX SBOM files for both reachable and unreachable images.
- Added symbols.json detailing function entry and sink points in the WordPress code.
- Included runtime traces for function calls in both reachable and unreachable scenarios.
- Developed OpenVEX files indicating vulnerability status and justification for both cases.
- Updated README for evaluator harness to guide integration with scanner output.

Raw Blame History

Crypto Routing Audit — 07 Nov 2025

Scope. Inventory direct uses of System.Security.Cryptography (and related primitives) outside the StellaOps.Cryptography* stack to identify callers that must be routed through sovereign-aware providers (default, PKCS#11, CryptoPro, future PQC).

Method. rg -l "using System.Security.Cryptography" src | grep -Ev "__Tests|\.Tests/" (filtered for runtime code). Counts reflect unique files per top-level module.

Configuring `crypto.regionalProfiles`

All hosts can now express provider ordering and profile overrides via configuration:

Crypto:
  registry:
    preferredProviders:
      - default
      - ru.pkcs11
    activeProfile: ru-offline
    profiles:
      ru-offline:
        preferredProviders:
          - ru.cryptopro.csp
          - ru.pkcs11
  pkcs11:
    keys:
      - keyId: ru-slot-token
        libraryPath: /usr/local/lib/librutokenecp.so
        slotId: "0x1"
        privateKeyLabel: signing-key
        certificateThumbprint: "<thumbprint>"
  cryptopro:
    keys:
      - keyId: ru-csp-token
        libraryPath: /opt/cprocsp/lib/libcapi20.so
        containerLabel: KRYPTO_PRO_KEY
        certificateThumbprint: "<thumbprint>"

Each deployment picks a profile (activeProfile) that resolves to a deterministic provider order, and individual services call into ICryptoProviderRegistry rather than new-ing crypto stacks directly.

Inspecting providers from the CLI

stellaops crypto providers now lists the registered providers, signing algorithms, certificate metadata, and the current preferred order. Use --json for machine-readable output or --profile <name> to preview another profile (e.g., ru-offline) before flipping configuration.

High-priority hotspots

Concelier (ingestion + mirror connectors)

src/Concelier/StellaOps.Concelier.WebService/Services/OpenApiDiscoveryDocumentProvider.cs – builds SHA256 hashes for discovery docs inline.
src/Concelier/__Libraries/StellaOps.Concelier.Connector.StellaOpsMirror/Security/MirrorSignatureVerifier.cs – performs RSA verification directly.
src/Concelier/__Libraries/StellaOps.Concelier.Connector.Ru.Nkcki/RuNkckiConnector.cs and .Ru.Bdu – local hash/signature handling for regional advisories.

Action: Introduce ICryptoProviderRegistry consumption inside connector/lib assemblies (probably through lightweight adapter service). File follow-up tasks in src/Concelier/StellaOps.Concelier.WebService/TASKS.md and connector TASK boards to migrate hashing/signing to the new PKCS#11/CryptoPro providers (priority for RU feeds to unblock RootPack_RU).

Scanner (web service, worker, Sbomer plug-ins)

src/Scanner/StellaOps.Scanner.WebService/Utilities/ScanIdGenerator.cs – direct SHA256 for id derivation.
src/Scanner/StellaOps.Scanner.WebService/Services/ReportSigner.cs – uses ECDsa.Create() directly for DSSE hand-off.
src/Scanner/StellaOps.Scanner.Worker/Processing/Surface/SurfaceManifestPublisher.cs – manual digesting before CAS writes.

Action: Create shared IScanCryptoService backed by ICryptoProviderRegistry so both web service and worker reuse sovereign providers. Add tasks under src/Scanner/StellaOps.Scanner.WebService/TASKS.md and src/Scanner/StellaOps.Scanner.Worker/TASKS.md.

Authority (plugins + signing host)

StellaOps.Authority/Signing/* classes still load PEM/PKCS#12 directly via X509Certificate2 and RSA.
AuthoritySecretHasher and AuthorityClientCertificateValidator maintain custom hashing.

Action: Wire Authority signing/loading paths to ICryptoProviderRegistry so active keys can point to ru.cryptopro.csp or ru.pkcs11. Open tasks in src/Authority/StellaOps.Authority/TASKS.md covering: signing key loading, JWKS generation, secret hashing migration.

Excititor / Attestor

Excititor connectors (e.g., src/Excititor/__Libraries/StellaOps.Excititor.Connectors.Ghsa/GhsaConnector.cs) re-hash payloads in place.
Attestor submission cache uses SHA256 for bundle ids.

Action: Introduce shared hashing helper that internally calls ICryptoProviderRegistry.ResolveOrThrow(CryptoCapability.Signing, SignatureAlgorithms.GostR3410_2012_256) for digest+sign combos; log follow-ups in respective TASK boards.

Evidence Locker / Export Center

Export packaging code manually builds SHA/V1 digests before signing manifests.

Action: Add backlog tasks for both modules to replace SHA256.Create() usage with provider-backed hashing (especially for offline bundle sealing).

Next steps

Open remediation tasks per module referencing this audit (minimum: Concelier, Scanner, Authority, Excititor, Attestor, Evidence Locker, Export Center). Each task should specify which files to migrate and target provider (default vs sovereign).
Provide shared helpers (e.g., ICryptoDigestService, ICasSigner) in StellaOps.Cryptography to ease adoption and avoid each module talking to the registry manually.
Follow-up audit once migrations land; rerun the command and ensure only StellaOps.Cryptography* and vetted crypto libraries contain direct System.Security.Cryptography usage.
RootPack validation runbook — see docs/security/rootpack_ru_validation.md for deterministic tests, hardware validation, and required audit artifacts before shipping RootPack_RU.
