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.

AC-20 Use of External Systems
addresses: CWE-668

Controls whether organization resources are exposed to external system spheres by permitting or prohibiting their use.

AC-21 Information Sharing
addresses: CWE-668

The control ensures information is not released into a security sphere where the recipient lacks matching access authorizations.

AC-22 Publicly Accessible Content
addresses: CWE-668

The control ensures information resources are not exposed to the incorrect (public) sphere through review and authorization.

AC-23 Data Mining Protection
addresses: CWE-668

Protects against data mining that would expose resources to unauthorized spheres by enforcing detection and controls.

AC-4 Information Flow Enforcement
addresses: CWE-668

Restricts information flows to ensure resources are not exposed to incorrect or unauthorized spheres.

CA-9 Internal System Connections
addresses: CWE-668

Controlling internal connections prevents exposure of resources to unintended internal spheres.

CM-12 Information Location
addresses: CWE-668

Knowing exact processing and storage locations helps avoid exposure of resources to incorrect spheres.

MP-2 Media Access
addresses: CWE-668

The control prevents exposure of the media resource to the wrong security sphere.

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-05 full match
prevents

Preventing execution of unauthorized code directly blocks the malicious binaries that an untrusted search path would load.

PR.AA-05 mostly match
prevents

Enforcing least-privilege authorizations directly prevents resources from being exposed outside their intended control sphere.

PR.PS-06 mostly match
prevents

Secure development practices include avoiding or sanitizing externally influenced search paths in application code.

PR.IR-01 partial match
prevents

Network segmentation and unauthorized-access protections reduce the chance of resources being reachable by the wrong sphere.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce safe search paths and restrict environment variables that enable the weakness.

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 discover search-path issues but does not itself prevent them in production code.

A.8.19 Installation of software on operational systems partial match
degrades

Restricting software installation reduces the chance that untrusted binaries or libraries are placed in search paths.

A.8.22 Segregation of networks partial match
mitigates

Placing systems of differing trust levels into separate domains prevents resources from being placed in a sphere where they are reachable by unintended actors.

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

Secure architecture principles include hard-coded or validated search paths and avoiding reliance on untrusted directories.

A.8.28 Secure coding partial match
prevents

Secure coding standards require absolute paths or integrity-checked search paths, directly mitigating CWE-426.

A.5.9 Inventory of information and other associated assets none match
none

Requiring owners to manage the full asset life cycle and remove assets from the inventory upon secure disposal helps prevent resources from being inadvertently exposed outside their intended security sphere.
