Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of software flaws like the unsafe privilege actions in the Drupal Role Delegation module, directly preventing exploitation via patching to version 1.5.0.

AC-6 Least Privilege good match

prevent

Enforces least privilege by limiting user roles to only essential permissions, mitigating privilege escalation from unsafe actions defined in the vulnerable module.

AC-2 Account Management partial match

prevent

Provides processes for managing accounts, roles, and privileges, enabling review and restriction of unsafe permissions granted by the Role Delegation module.
