Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-1 Policy and Procedures
addresses: CWE-250

Policy promotes least privilege by defining necessary privileges and management commitment to them.

AC-13 Supervision and Review — Access Control
addresses: CWE-250

Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.

AC-2 Account Management
addresses: CWE-250

Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.

AC-5 Separation of Duties
addresses: CWE-250

Separation of duties prevents any single user from holding all privileges needed to complete a critical task, directly reducing execution with unnecessary privileges.

AC-6 Least Privilege
addresses: CWE-250

Directly prevents execution with more privileges than needed for assigned tasks.

AT-3 Role-based Training
addresses: CWE-250

Role-based training on least privilege principles reduces the chance personnel assign or retain unnecessary privileges.

AU-6 Audit Record Review, Analysis, and Reporting
addresses: CWE-250

Analysis of audit records can identify execution with unnecessary privileges through unusual activity patterns.

CA-9 Internal System Connections
addresses: CWE-250

Automatic termination after a defined period eliminates unnecessary privileges from persistent connections.

PR.AA-05 mostly match
prevents

PR.AA-05 directly enforces least privilege so largely eliminates CWE-250 at design time, yet the weakness can still arise from runtime escalation paths, third-party code, or misapplied role definitions outside this single control.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.18 Access rights mostly match
prevents

Requiring explicit justification and time-limited grants discourages the routine allocation of unnecessary privileges that would otherwise allow execution with more rights than required.

A.8.18 Use of privileged utility programs mostly match
prevents

Restricting privileged utilities to the fewest trusted users and requiring explicit authorization directly stops developers or operators from embedding or invoking code that runs with unnecessary elevated rights.

A.8.2 Privileged access rights mostly match
prevents

Mandating separate non-privileged identities for routine work and restricting privileged accounts to administrative tasks reduces the chance that everyday operations run with unnecessary elevated rights.

A.8.9 Configuration management mostly match
prevents

The control explicitly calls for minimizing privileged identities and disabling unnecessary accounts, thereby reducing the number of processes that run with unnecessary privileges.

A.5.15 Access control partial match
prevents

The requirement to restrict privileged access and apply segregation of duties limits the number of processes or accounts that must run with elevated rights, lowering the impact of unnecessary privilege assignments.

A.5.3 Segregation of duties partial match
mitigates

Forcing distinct roles for initiating versus executing changes reduces the chance that an individual will run with unnecessary privileges to perform both steps.
