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.

SI-10 Information Input Validation
addresses: CWE-73

Rejects externally supplied file or resource identifiers that fail validity checks.

SI-22 Information Diversity
addresses: CWE-610

Limits impact of an externally controlled reference to a primary information resource by switching to an identified alternative.

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 full match
prevents

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

PR.AA-05 mostly match
prevents

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

DE.CM-09 partial match
prevents

Runtime monitoring of software and data flows can detect anomalous external resource accesses that result from this weakness.

PR.IR-01 partial match
prevents

Network segmentation and access controls limit the blast radius when an external reference escapes its intended sphere.

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 path-traversal issues but does not itself implement preventive controls.

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.8.3 Information access restriction partial match
mitigates

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