Open Biller 0.1 Blind SQLi exploit

The vulnerability exists due to insufficient sanitization of the 'username' parameter in the 'login.php' script. An attacker can inject arbitrary SQL commands and gain access to the application. The exploit is achieved by sending a specially crafted HTTP request with the malicious 'username' parameter.

Mitigation:

Input validation should be used to prevent SQL injection attacks.
