DescriptionCVE.org

A vulnerability has been found in SourceCodester Prison Management System 1.0. The impacted element is an unknown function of the component Login. The manipulation leads to session fixiation. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

Executive ViewAI

Why It Matters

A high-severity vulnerability in SourceCodester Prison Management System 1.0 affects the login component and poses immediate risk to user authentication and system access control. With a public exploit available and no vendor patch currently released, unauthorized access to sensitive correctional facility data and operations is a material risk that requires urgent containment measures.

Business Impact: Severe

Compensating Controls

Implement Web Application Firewall (WAF) rules to restrict login endpoint access; enforce network segmentation to limit access to the Prison Management System to authorized administrative networks only; disable remote access to the login component if operationally feasible; enforce multi-factor authentication at the network or application layer; increase login attempt rate-limiting and account lockout thresholds; deploy intrusion detection/prevention systems (IDS/IPS) with signatures for known exploit patterns; maintain enhanced audit logging of all authentication attempts.
