PHP-Nuke 'Seminars' Module - 'Filename' Local File Inclusion

source: https://www.securityfocus.com/bid/28089/info

The PHP-Nuke 'Seminars' module is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.

Exploiting this issue may allow an unauthorized remote user to view files and execute local scripts in the context of the webserver process.
