Hotfix Release: 11/09/2013

Local File Inclusion
This script does not properly sanitize user input before including the
language settings file in index.php.

An attacker can exploit this vulnerability by sending a malicious "lang"
$_POST string. Versions <=1.3 prior to hotfix are affected.

Vulnerable Code
Line 90:
if ($_SESSION["lang"] == "" || isset($_POST["lang"]))

setLangFile();



include("languages/".$_SESSION["lang"]);

Line 3771:
function setLangFile() {



// The order of these determines the proper display

if ($_COOKIE["lang"] != "")

$lang = $_COOKIE["lang"];

if ($_SESSION["lang"] != "")

$lang = $_SESSION["lang"];

if (isset($_POST["lang"]))

$lang = $_POST["lang"];



if ($lang == "") {



$dir = "languages";



if (is_dir($dir)) {

if ($dh = opendir($dir)) {

while (($file = readdir($dh)) !== false) {

if ($file != "." && $file != "..") {



include("languages/".$file);



if ($file_lang_default == 1)

$lang = $file;

}

}

closedir($dh);

}

}

}



// Sanitize file path

$lang = santizePath($lang);



$_SESSION["lang"] = $lang;

}
