The remote web server contains a PHP script that is prone to remote file inclusion attacks.
The remote host is running Nucleus CMS, an open-source content management system. The version of Nucleus CMS installed on the remote host fails to sanitize input to the 'DIR_LIBS' parameter before using it in a PHP include() function in the 'nucleus/libs/PLUGINADMIN.php' script. Provided PHP's 'register_globals' setting is enabled, an unauthenticated attacker may be able to exploit this flaw to view arbitrary files on the remote host or to execute arbitrary PHP code, possibly taken from third-party hosts.
Upgrade to version 3.23 or higher.
