Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Directly requires validation of path inputs, stopping the acceptance of backslash dot-dot sequences that escape the restricted directory.

AC-3 Access Enforcement partial match

Enforces authorization checks on file/resource access, blocking exploitation of a traversed path even if the malformed name is accepted.

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 input validation and path sanitization that block this weakness.

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 discover traversal flaws but does not prevent them at the source.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and path sanitization that directly blocks directory traversal sequences.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against path traversal and other injection flaws.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific coding fix.

A.8.28 Secure coding partial match
prevents

Secure coding standards require canonicalization and whitelist validation that eliminate CWE-31.
