CVE-2023-30840

Periodic review and update of procedures reduces incorrect authorization implementations over time.

Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.

Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.

The authorization process and usage restrictions help prevent incorrect authorization for remote access types.

Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.

Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.

Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.

Ensures authorization decisions for external system use are correctly implemented and enforced.

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

A.5.18's provisioning, revocation, review and adjustment of access rights (incl. before role changes/termination, with segregation and owner approval) directly stops incorrect authorization decisions from being exploitable in the vast majority of cases; the bounded remainder is incorrectness inside the authorization logic itself (e.g. flawed conditional or missing check) rather than rights that were wrongly granted.

A.8.3 directly mandates restricting access to information per policies via configuration, identity/group controls, isolation, and dynamic techniques that enforce correct authorization decisions, addressing most but not all slices of CWE-863 (e.g., remainder in non-access-decision authorization errors like timing or environmental factors).
