Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly requires remediation of the specific software flaw enabling privilege escalation in Xagio SEO plugin versions through 7.1.0.30.

AC-6 Least Privilege good match
prevent

Enforces least privilege to prevent exploitation of incorrect privilege assignment allowing unauthenticated attackers to escalate privileges.

AC-3 Access Enforcement good match
prevent

Mandates enforcement of access authorizations to block unauthorized privilege escalations via the plugin's flawed logic.
