DescriptionCVE.org

A vulnerability was determined in itsourcecode School Management System 1.0. This affects an unknown function of the file /ramonsys/inquiry/index.php. This manipulation of the argument txtsearch causes sql injection. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized.

Executive ViewAI

Why It Matters

A high-severity vulnerability in School Management System 1.0 allows unauthenticated attackers to exploit the inquiry module, potentially compromising student and institutional data. With active public exploits available and no vendor patch released, immediate action is required to prevent unauthorized access to sensitive educational records and system compromise.

Business Impact: High

Compensating Controls

Implement WAF rules to block/monitor access to /ramonsys/inquiry/index.php; restrict network access to the application via IP whitelisting; disable the inquiry module if operationally feasible; segment affected systems behind VPN or firewall; enforce multi-factor authentication; enable and monitor security logs for exploitation attempts; consider deploying a reverse proxy with input validation rules.
