CVE-2023-52139

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

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

The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.

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.

Mapping access rights to information classification and business requirements forces correct enforcement of authorization decisions, blocking the incorrect authorization weakness at the policy and implementation stage.

Independent reviewers evaluate whether authorization logic matches policy, thereby reducing the window in which incorrect or missing authorization checks remain in production.

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.

Requiring authorization processes and privilege assignments to be specified during project initiation prevents downstream components from receiving overly broad or incorrect rights that would allow unauthorized actions.

A.8.3 directly mandates and configures the authorization mechanisms (identity/group rights, dynamic access rules, isolation, credential enforcement) that stop CWE-285 exploitation; the bounded remainder is non-authorization exposure vectors such as error messages or observable discrepancies.
