DescriptionCVE.org

A vulnerability was identified in code-projects Online Examination System 1.0. Affected by this issue is some unknown functionality of the file login.php. The manipulation of the argument username/password leads to sql injection. The attack may be initiated remotely.

Executive ViewAI

Why It Matters

A high-severity vulnerability in the Online Examination System's login functionality could allow attackers to gain unauthorized access to student and staff accounts, potentially compromising sensitive academic records and personal information. With no patch currently available, immediate interim protections are required to prevent exploitation while awaiting vendor remediation.

Business Impact: High

Compensating Controls

Implement WAF rules to monitor and block suspicious login patterns; enable rate limiting on login.php; restrict login.php access via network segmentation to authorized IP ranges only; enforce multi-factor authentication (MFA) if supported by the application; increase logging and alerting on authentication failures; consider temporarily disabling the online examination feature and reverting to alternative assessment methods until patch is available.
