## 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: ##
## $ ./ipb ##
## IPB Forum URL ? forums.example.com/forums ##
## Your username ? krypt_sk1dd13 ##
## Your pass ? if_your_on_nix_this_gets_hidden ##
## Target userid ? 3637 ##
## ##
## Attempting to extract password hash from database... ##
## 537ab2d5b37ac3a3632f5d06e8e04368 ##
## Hit enter to quit. ##
## ##
## Requirements: ##
## o Perl 5 ##
## o LWP 5.64 or later ##
## o Internet access ##
## o A forum you hate/dislike ##
## o A user on said forum ##
## o 32+ PMs left till your inbox is full, if not you can still delete ##
## PMs from your inbox as the successful ones come through ##
## ##
## Credit to: Nuticulus for finding the SQL injection ##
## ##
## Have fun, you dumb skiddie. ##

| 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  |

Yes I have the same problem 
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. |
