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-862

Requiring an access control policy ensures authorization checks are defined and applied for critical functions.

AC-13 Supervision and Review — Access Control
addresses: CWE-862

Reviews of access controls detect missing authorization checks on critical functions or resources.

AC-14 Permitted Actions Without Identification or Authentication
addresses: CWE-862

Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.

AC-16 Security and Privacy Attributes
addresses: CWE-862

Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.

AC-17 Remote Access
addresses: CWE-862

Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.

AC-18 Wireless Access
addresses: CWE-862

Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.

AC-19 Access Control for Mobile Devices
addresses: CWE-862

The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.

AC-2 Account Management
addresses: CWE-862

Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.

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-04 full match
prevents

Protecting, conveying, and verifying identity assertions specifically prevents the spoofing that enables authentication bypass.

PR.AA-05 full match
prevents

Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing authorization checks.

PR.AA-03 mostly match
prevents

Requiring authentication of users/services/hardware directly counters spoofing-based bypass when strong methods are used.

PR.AA-02 partial match
prevents

Proofing and binding identities reduces spoofing opportunities during enrollment but does not address runtime authentication implementation flaws.

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.8.5 Secure authentication full match
degrades

Secure authentication control directly mitigates authentication bypass by spoofing.

A.5.17 Authentication information mostly match
degrades

Authentication information management directly addresses credential handling that prevents spoofing.

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

Security testing can detect spoofing vulnerabilities but does not prevent them by itself.

A.8.3 Information access restriction mostly match
prevents

Requiring authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.

A.5.15 Access control partial match
prevents

Access control policy reduces spoofing opportunities but does not prescribe authentication mechanisms.

A.5.16 Identity management partial match
prevents

Identity management supports unique identities but does not guarantee resistance to spoofing.
