Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly neutralizes '../' sequences in externally-supplied pathnames before they are resolved.

AC-3 Access Enforcement partial match

Enforced access authorizations can limit the damage even when path traversal succeeds.

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 partial match
blocks

Secure SDLC practices directly require input validation and path sanitization that prevent ../ traversal.

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.8.19 Installation of software on operational systems partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure SDLC mandates input validation and path canonicalization that directly block ../ traversal.

A.8.26 Application security requirements partial match
blocks

Application security requirements explicitly call for controls against path traversal in file-handling functions.

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

A.8.27 mandates security-by-design principles (least privilege, default-deny, distrust-external-input, fail-securely, hardening, design review against attack patterns) that reach a minority slice of path-traversal defects when applied to input handling and directory restrictions; most instances remain possible if the specific neutralization is omitted.

A.8.28 Secure coding partial match
prevents

Secure coding standards require neutralizing ../ sequences and canonicalizing paths before file operations.

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

Security testing in development catches path-traversal flaws before release.
