Executive ViewAI

Why It Matters

A high-severity vulnerability exists in the SourceCodester Online Class Record System's admin login functionality that could allow attackers to compromise administrative accounts and gain unauthorized access to student records and system controls. This poses a significant risk to data confidentiality, institutional liability, and operational continuity for any organization using this system.

Business Impact: High

Compensating Controls

Implement Web Application Firewall (WAF) rules to monitor and block suspicious authentication attempts; enforce multi-factor authentication (MFA) on all admin accounts; restrict admin login access to whitelisted IP addresses or VPN only; increase logging and alerting on failed login attempts; consider disabling remote admin access and requiring local network access only; conduct regular credential rotation; deploy intrusion detection system (IDS) monitoring for exploitation patterns. Contact vendor for patch timeline as no patch is currently available.
