Mitigating Controls (NIST 800-53 r5) AI

AC-6 Least Privilege good match
prevent

Least privilege on the End-User Notifications process directly limits the files it can delete, blocking exploitation of the CWE-59 link-following flaw.

SI-10 Information Input Validation good match
prevent

Input validation of file paths and link targets prevents the tool from resolving and deleting unintended files via symbolic links.

SI-7 Software, Firmware, and Information Integrity partial match
detect

Integrity verification of critical files can detect unauthorized deletions resulting from the arbitrary-file-delete vulnerability.

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 code to validate paths and avoid unsafe link following.

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
detects

Security testing can detect link-following flaws before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC practices can mandate link-resolution checks and canonicalization before file access.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly require safe handling of symbolic links and path traversal.

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

Secure architecture principles include input validation and safe file-access design patterns.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address canonicalization and symlink attacks during implementation.

A.8.3 Information access restriction none match
none

Access-control rules can limit which files are reachable, reducing exposure to malicious links.
