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.

addresses: CWE-668

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

addresses: CWE-668

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

addresses: CWE-668

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

addresses: CWE-668

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

addresses: CWE-668

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

addresses: CWE-668

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

addresses: CWE-668

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

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.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 SDLC practices directly require input neutralization and query parameterization that prevent XPath injection.

PR.IR-01 partial match
prevents

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

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.

prevents

Secure coding standards require proper neutralization of untrusted input in XPath expressions.

finds

Security testing in development catches XPath injection vulnerabilities before release.

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.

prevents

Secure SDLC mandates input validation and query parameterization that directly prevent XPath injection.

prevents

Application security requirements explicitly call for defenses against injection flaws including XPath injection.

prevents

Secure architecture principles reduce the likelihood of unsafe dynamic query construction.
