Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

AC-3 Access Enforcement partial match

Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.

AC-6 Least Privilege partial match

Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

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.AA-05 partial match
prevents

Least-privilege file authorization directly limits damage from externally controlled paths.

PR.PS-06 partial match
prevents

Secure SDLC practices include input validation and path sanitization that eliminate 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.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

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

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

A.8.28 Secure coding partial match
prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

A.8.29 Security testing in development and acceptance partial match
finds

Security testing can detect path-traversal issues but does not itself implement preventive controls.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
