## IPB <=2.1.4 exploit (possibly 2.1.5 too)                                ##
## Brought to you by the Ykstortion security team.                         ##
##                                                                         ##
## The bug is in the pm system so you must have a registered user.         ##
## The exploit will extract a password hash from the forum's data base of  ##
## the target user.                                                        ##
## You need to know the target user's member ID but it's not difficult to  ##
## find out, just look under their avatar next to one of their posts.      ##
## Once you have the hash, simply unset all forum cookies and set          ##
## member_id to the target user's member id and pass_hash to the hash      ##
## obtained from the database by this script.                              ##
##                                                                         ##
## Usage:                                                                  ##

Hi, i am realy new at IPB, but over the past 3 months of using it i have been hacked time and time agian, to the point of were i want to change forums, i believe that this is how i was hacked this time, i understand that to use this script the hacker needed to use a remote include, but i dont see how it was done, i was wondering if someone could help me out by telling me how to exicute this script, i know that i need to create a file with the above script and upload it to a server, but what commands do i use from there?

Sorry for my stupid post, but I am new here.
Could you tell me please what to do with this code, where to put it.
I know that I need Perl 5 and LWP 5.64, but I don't know what to do with them.
And I want to ask does it work with IPB 2.1.2?
Thanks

As written in exploit - "IPB <=2.1.4 exploit" - so it should work with 2.1.2 too. How to use?

I assume, that you are using windows and have allready installed Activeperl:

http://www.activestate.com/Products/ActivePerl/?psbx=1

Create directory "c:/ipb" and new text file in it, called "ipb.pl".
Now copy/paste exploit text to new file.
Next, open command prompt (start->run->cmd) and navigate to ipb folder, using "cd" commands.
And when you are in ipb folder, issue command "perl ipb.pl".
That's all - perl script will question some input parameters, like target server url and other stuff. And next - happy haxing Smile

Yes I have the same problem Sad
Instead I got the md5 hash, I got 32 zeroes!
And when I check my inbox, i received a message with subject:
asdf
and a text in it:
jkl

but I can't find the md5 hash (it is not in the clipboard).
Maybe the problem is because I use ActivePerl(5.8.8 build 817) with Win2000, or the forum has some kind of security.
I would be very grateful if somebody has any idea about this problem.
