CVE-2023-20274

Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments.

Access supervision ensures privileges are assigned and managed without improper escalation or retention.

Assigning group/role memberships and access authorizations (privileges) while reviewing accounts addresses improper privilege management.

Enforces proper privilege management by requiring all decisions through the verified reference monitor.

By mandating division of duties across roles, the control enforces proper privilege management and prevents a single entity from controlling an entire sensitive process.

Implements core proper privilege management by restricting to only required rights.

Policy requires training on privilege management and least privilege, making it harder to exploit improper privilege management weaknesses.

Training covers proper privilege management practices, making incorrect privilege assignments less likely.

A.5.15 directly mandates determining access requirements, defining/enforcing topic-specific access control policy, assigning rights/restrictions by entity/role, consistency with classification, need-to-know, privileged access restrictions, segregation, formal authorization, and dynamic rules — which stops most improper privilege management from being exploitable; bounded remainder is flawed implementation of those rules (e.g. incorrect mapping or enforcement bugs).

A.5.18 directly governs the provisioning, review, modification and timely revocation of access rights (including for role changes, termination and privilege levels), which stops most improper privilege spheres from being exploitable even if the assignment flaw exists; the bounded remainder is flaws in the underlying enforcement mechanism itself (e.g. AC-3/A.8.3)

Defining and communicating authorization levels for each role limits the assignment of excessive or unnecessary privileges.

Logging every use of privileges and protecting those records makes it harder for an attacker who has obtained elevated rights to operate without leaving evidence.

A.8.2 directly controls the identification, allocation, review, expiry, temporary use, and separation of privileged rights per policy, which prevents most improper privilege management (CWE-269) by design; the bounded remainder is flawed tracking/checking logic inside the product's own enforcement code (the AC-3 slice of 269).

A.8.27 mandates security-by-design principles including least privilege, default deny, fail securely, defence in depth, security architecture integration, hardening, and zero-trust verification of every request; these directly stop most improper privilege spheres from being exploitable even if the assignment flaw remains, with a bounded remainder (e.g. certain legacy or safety-overridden controls).
