CVE-2023-3124

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

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

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

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

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

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

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

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

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

A.5.18's provisioning, review, revocation and activation steps (incl. owner approval, SoD, timely removal on role/termination change) directly stop exploitation of missing authorization checks by ensuring no actor receives or retains rights to resources they should not access; the bounded remainder is that it cannot stop missing-authorization defects inside the enforcement mechanism itself once rights have been granted (e.g. flawed code that ignores the rights table).

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

A.5.8 integrates risk assessment, requirements elicitation and governance into the project lifecycle so that authorization needs can be identified and specified; it does not itself perform or enforce authorization checks, so the missing-authorization weakness can still be present and exploitable.

Security checkpoints and explicit authorization requirements in the design phase ensure that every sensitive function is paired with an access-control check, reducing missing-authorization defects.

A.8.27 mandates security-by-design principles (least privilege, default deny, security architecture integration, zero-trust never-trust/always-verify, dynamic access control) plus design reviews that directly specify and enforce authorization checks before access; this stops most missing-authorization cases from being exploitable, with a bounded remainder in non-architectural or legacy components where the principles were documented but not fully applied.
