Executive ViewAI

Why It Matters

A high-severity vulnerability in the Online Examination System's login component (CVE-2026-1422) poses a significant risk to user authentication and data security. With public exploits available and no vendor patch currently released, unauthorized attackers could potentially compromise user accounts and access sensitive examination data, impacting institutional credibility and regulatory compliance.

Business Impact: High

Compensating Controls

Deploy Web Application Firewall (WAF) rules to detect and block exploitation patterns targeting /index.php; implement rate limiting on login endpoints; enforce multi-factor authentication; restrict network access to login functionality via IP whitelisting; enable detailed logging and SIEM alerts for authentication anomalies; consider temporarily disabling the affected system if alternative examination platforms are available; isolate affected systems to a segregated network segment with enhanced monitoring.
