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 partial match
blocks

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
blocks

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
blocks

A.5.18 governs the provisioning, review, and revocation of access rights based on authorization and policy; it does not verify resource ownership and cannot stop exploitation of unverified ownership.

A.8.19 Installation of software on operational systems partial match
removes
A.8.2 Privileged access rights partial match
blocks

A.8.2 controls the allocation, review, expiry and use of privileged rights via authorization and least-privilege rules; it has no bearing on whether a resource's ownership is verified before use, so the CWE-283 weakness can still be present and exploited.

A.8.26 Application security requirements partial match
removes
