How CVE-2025-4721 Works
This vulnerability exists in the `drive.php` file of Placement Management System 1.0 due to improper sanitization of the `ID` parameter. Attackers can inject malicious SQL queries via this parameter, leading to unauthorized database access. The flaw allows remote exploitation without authentication, enabling attackers to extract sensitive data, modify records, or execute administrative operations. The SQL injection occurs because user-supplied input is directly concatenated into SQL statements without proper validation or prepared statements.
