Executive ViewAI

Why It Matters

A high-severity vulnerability in the Online Reviewer System could allow unauthorized users to access or manipulate assessment questions and sensitive academic data. With no patch available and a public exploit in circulation, immediate action is required to protect student records and assessment integrity.

Business Impact: High
Compensating Controls

Implement Web Application Firewall (WAF) rules to restrict access to /system/system/admins/assessments/pretest/questions-view.php; apply IP whitelisting to limit access to administrative functions; disable the affected assessment feature if operationally feasible; enforce multi-factor authentication for admin accounts; isolate the application on a segmented network with restricted egress; implement real-time monitoring and alerting for suspicious access patterns; consider air-gapping or temporary offline backup of assessment data.
