Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-25 Thin Nodes
addresses: CWE-489

Minimal functionality precludes inclusion of active debug code or diagnostic interfaces.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require removal of debug code before release, covering most of this weakness while the control addresses many other development issues.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
detects

Security testing in development and acceptance catches active debug code before deployment.

A.8.9 Configuration management mostly match
prevents

Configuration management can disable or remove debug features through hardened baselines.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates removal of debug code before release.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly prohibit leaving debug code active in production.

A.8.31 Separation of development, test and production environments partial match
prevents

Separation of environments reduces risk of debug code reaching production but does not directly address its removal.

A.8.32 Change management partial match
prevents

Change management can enforce removal of debug code as part of release gates.
