Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces the access control policy that defines permissions on resources, thereby stopping incorrect assignments from remaining exploitable.

AC-6 Least Privilege good match

Directly requires assignment of only the minimum necessary permissions, preventing overly broad grants on critical resources.

CM-6 Configuration Settings good match

Establishes restrictive configuration settings that can define and lock down approved search paths.

CM-5 Access Restrictions for Change partial match

Restricts logical and physical access to change system configuration, including search-path settings and directories.

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 full match
prevents

Directly requires defining, enforcing, and reviewing access permissions and least privilege on resources.

PR.PS-01 mostly match
prevents

Hardened baselines and configuration management explicitly include correct permission settings for critical resources.

PR.PS-06 mostly match
prevents

Secure-development practices directly address design of search paths and resource loading.

PR.PS-05 partial match
prevents

Execution allow-listing can block malicious binaries placed in hijackable search locations.

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.5.15 Access control mostly match
prevents

By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.

A.5.18 Access rights mostly match
prevents

Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.

A.8.2 Privileged access rights mostly match
prevents

Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.

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

Security testing can detect uncontrolled search-path issues but does not prevent them by itself.

A.8.3 Information access restriction mostly match
prevents

Requiring explicit configuration of access controls and permissions for files, applications and services counters the assignment of overly permissive default or incorrect file-system rights.

A.8.4 Access to source code mostly match
prevents

Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.
