I think you just log in with your own account, then edit the cookie and you will be the mod or admin.
But im not sure how you get the sid. |

You should clear your cookies and replace your session ID with the exploited session. Refresh the page and you *should* be logged in with the username of whoever closed the thread. |

Remember, sessions time out after about 30 minutes - after which time they become useless. You need a fresh session for session hijacking to work.
I also noticed that the session ID "SID" has not been changed since you changed it. Make sure you get rid of "&sid=blablabla" in the URL before you refresh the page. |

meh can't get it to work
I edit the cookie and make it just like it was, when I was logged in
as admin and still doesn't work. :/
The session is a few seconds old.
I don't get it. |

Hmmm.... well make sure you don't log out from admin before you try the exploit. If the admin logs out, then the session will be automatically invalidated
best way to get around this when testing exploits like this is to use two different browsers - for example firefox and safari Use firefox as your pretend victim logged in as admin, and on safari dont login until you have the session |

jeeeeeeeeeeeej finally werx, thx dude
This is gonna be tough to exploit .
If I would get the SID from an admin I would have to guess what his/her user ID is or is there a better way?
I would have to edit the user ID in this part of the cookie?
a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%222%22%3B%7D
Also the referrer info is updated every hour on awardspace.com :/
So I think im gonna have to use my server at localhost, but I really dont like the idea of that! |

ah found the user ID part
a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%222%22%3B%7D
admin user ID in this case is 2
I made a new normal user and this is the cookie:
a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%223%22%3B%7D
user ID is 3 |

just one more question:
Is there a way to host a picture that doesnt get caches, like a broken or not existing image. Will you still get the referer info? Maybe some other trick?
Because if the picture gets cashed I wont get the referer info when its loaded? |

Ive tested this, and its better to use a non existing image because
it cant be cached by the victims browser, giving you a bigger chance of succeeding
Exploit works great, only a little social engineering is needed |

For the people who may be interested, I have written a little C++ app.
that checks the apache access_log for SID's every 5 seconds and outputs
them the command line and writes them to a file. |
