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-1 Policy and Procedures
addresses: CWE-863

Periodic review and update of procedures reduces incorrect authorization implementations over time.

AC-13 Supervision and Review — Access Control
addresses: CWE-863

Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.

AC-16 Security and Privacy Attributes
addresses: CWE-863

Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.

AC-17 Remote Access
addresses: CWE-863

The authorization process and usage restrictions help prevent incorrect authorization for remote access types.

AC-18 Wireless Access
addresses: CWE-863

Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.

AC-19 Access Control for Mobile Devices
addresses: CWE-863

Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.

AC-2 Account Management
addresses: CWE-863

Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.

AC-20 Use of External Systems
addresses: CWE-863

Ensures authorization decisions for external system use are correctly implemented and enforced.

PR.AA-05 mostly match
prevents

Enforcing defined access permissions and authorizations directly prevents missing ownership verification for resources.

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 partial match
prevents

Access control policies can require ownership verification before granting access to critical resources.

A.5.16 Identity management partial match
degrades

Identity management processes can include verification of resource ownership during provisioning and access decisions.

A.5.18 Access rights partial match
prevents

Access rights reviews can enforce checks that only legitimate owners retain privileges over critical assets.

A.8.2 Privileged access rights partial match
prevents

Privileged access rights assignment should verify ownership to prevent unauthorized elevation on critical resources.

A.8.3 Information access restriction partial match
mitigates

Information access restriction mechanisms can implement ownership checks before allowing operations on protected resources.

A.8.5 Secure authentication partial match
degrades

Secure authentication can be extended to verify resource ownership in addition to user identity.
