Mitigating Controls (NIST 800-53 r5) AI

SI-11 Error Handling good match

SI-11 requires error messages (including debug/diagnostic output) to avoid exposing exploitable system details, directly stopping the described information leakage.

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 sanitizing or removing debug messages that leak internal information.

PR.PS-01 partial match
prevents

Configuration baselines can disable debug output in production, partially preventing exposure of sensitive details.

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
finds

Security testing can detect excessive debug information, but does not guarantee its prevention in production.

A.8.9 Configuration management mostly match
prevents

Configuration management can disable debug flags, providing partial mitigation without covering the control's broader scope.

A.8.15 Logging partial match
prevents

Logging control requires that only necessary information is recorded, directly mitigating debug messages that leak sensitive data.

A.8.28 Secure coding partial match
prevents

Secure coding practices mandate removal or protection of debug output containing sensitive information before release.

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

Separation of environments reduces risk of debug exposure in production but does not address the weakness itself.
