Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Timely identification, reporting, and correction of the authentication bypass flaw in the SetSail Membership plugin prevents unauthenticated attackers from logging in as any user including administrators.

IA-2 Identification and Authentication (Organizational Users) good match

prevent

Requires systems to uniquely identify and authenticate users before granting access, directly addressing the plugin's failure to properly verify identity through social login.

SI-4 System Monitoring partial match

detect

Monitors the system for unauthorized connections and access attempts, enabling detection of account takeovers resulting from the authentication bypass.
