CVE-2023-1167

Documented procedures facilitate correct implementation and ongoing management of authorization decisions.

Periodic reviews identify and correct flaws in authorization decisions or enforcement.

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

Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.

Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.

The control explicitly requires authorization of each wireless access type prior to permitting connections.

Mandating explicit authorization of mobile device connections reduces the risk of improper authorization decisions for system access.

Specifying access authorizations for each account and requiring approvals for account requests enforces proper authorization decisions.

A.5.1 only requires the existence of an overarching policy and topic-specific policies (including on access control); it does not itself perform or enforce any authorization check, so the CWE-285 weakness can still be exploited.

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.

By requiring managers to verify that authorization decisions match policy and to remediate deviations, the control limits the persistence of incorrect or missing authorization checks.

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.
