SOFTWARE: mx_modsdb (module for MxBB Portal) 1.x - http://secunia.com/product/12884/

DESCRIPTION: Lu7k has discovered a vulnerability in the mx_modsdb module for MxBB Portal, which can be exploited by malicious people to compromise vulnerable systems.

Input passed to the "module_root_path" parameter in includes/common.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources. Successful exploitation requires that "register_globals" is enabled. The vulnerability is confirmed in version 1.0.0. Other versions may also be affected.
