Technical details

The vulnerability is a classic unauthenticated SQL injection (CWE-89) in the login component (/dets/index.php). The email parameter from the POST request is concatenated directly into a SQL query without sanitization or parameterized statements, while the password is hashed with MD5 before insertion. An attacker can inject SQL operators in the email field—such as `' OR '1'='1' LIMIT 1-- -`—to bypass authentication and login as the first user in the database or any known user. No server-side validation, escaping, or prepared statements are implemented. Network access is required and no authentication is needed to exploit this vulnerability. Remediation requires use of prepared statements with parameter binding and server-side input validation.
