Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Requires identification, reporting, and timely correction of the specific flaw in GreaterWMS <=2.1.49 that enables credential disclosure via the /staff route.

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations to block unauthenticated remote access to the vulnerable /staff route, preventing authentication bypass and privilege escalation.

AC-6 Least Privilege partial match

prevent

Limits damage from disclosed staff credentials by restricting privileges to the minimum necessary, mitigating escalation impact.
