Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation of file paths directly rejects or normalizes the special-character manipulations that create equivalent names.

AC-3 Access Enforcement partial match

Proper enforcement of file access authorizations structurally blocks disclosure when equivalent paths are presented.

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 prevent introduction of improper path-resolution logic in software.

PR.IR-01 partial match
prevents

Path-equivalence flaws enable unauthorized file access that network segmentation and logical access controls can partially block.

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.8.28 Secure coding mostly match
prevents

Secure coding standards directly require canonical path resolution and input sanitization to prevent equivalence attacks.

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

Security testing can detect path-equivalence flaws before release, partially fulfilling the control.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes path-handling requirements that reduce equivalence-based disclosure.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate canonicalization and input validation to block path equivalence.

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

Secure architecture principles call for safe file-system abstractions that mitigate path traversal risks.

A.8.3 Information access restriction none match
none

Information access restriction limits what files can be reached, indirectly reducing impact of path-equivalence exploits.
