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.

AU-1 Policy and Procedures
addresses: CWE-117

Policy and procedures require sanitization and neutralization when generating audit logs to avoid injection issues.

SI-15 Information Output Filtering
addresses: CWE-117

Requiring output to conform to expected content prevents unneutralized data from reaching logs.

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 and coding standards directly require output sanitization for logs.

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 log injection flaws but does not prevent them at the source.

A.8.15 Logging partial match
degrades

Logging control directly requires proper log generation and handling, which mitigates improper output neutralization.

A.8.16 Monitoring activities partial match
finds

Monitoring activities rely on trustworthy logs but do not ensure log message integrity.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC includes coding standards that reduce log-related weaknesses but does not specifically address logging.

A.8.28 Secure coding partial match
prevents

Secure coding practices mandate input validation and output encoding, directly preventing log injection.
