It would work where admin functions are done by constructing a url.
If a forum used a url like
http://www.site.com/functions.php?f=1337&function=lock_thread
to lock the thread with the number 1337 you would just have to have
location:http://www.site.com/functions.php?f=1337&function=lock_thread in your script to force the admin or moderator to lock the thread.
They would be redirected there, and would be authorised to perform the function, so the script would just do it. |

actually i may have offered not-so good way to patch this vulnearability.
i contacted one forum admin (of xmb), and he suggested as follows:
to make GET url unique.. like adding a must-be ID (which is validated via database) to urls. like: logout.php?action=logout&uniqid=afasdf.. and that id is different each time.. so the attacker doesnt know where to redirect victim exacly and prevents stuff from working. so if implemented right it would work. |

It was just an example of a possability.
On phpbb the most you can do it log them out by the looks of it. |

Hi, I'm trying to use this vulnerability to get the forum to open my web page in the forum users browser.
I have tried saving my page as index.htm and putting it into the signature.jpg folder but this does not work.
Now I am thinking that I should have some php code saved as my index.htm and that this code should open the page in their browser. It would be similar to the code that is being used to log users out, only it would load my page instead.
I do not know any PHP so could someone please help me and post some code that would do this. I want to open my page in the existing window, not in a new window. Thanks |

first of all,no need to fight or flaming just because of small thing.
releasing poc for it,for those dont believe it. try it out
make yourself a folder .. like darkclaw said.
rename the folder to signature.jpg
this will trick bbcode that its an image file.
example http://sitewithcode/signature.jpg
inside that folder .. put this code ..
and rename it to index file.
this will make every visitor getting logout when they viewing the thread that
have image linked to this or maybe delete the posting using admin privileage once admin view it. Always better to PM admin to make sure its work . |
is there anyway we can generate this code via avatar but with a valid picuture (embeded with the xss code) so we can get rid of the X when the code is generaded...
or, how do I make it invisible?

I dont think its possible because the headers sent would need to be for an image and not for a redierect.
as far as i know you wont be able to send both image AND redirect headers from the same script. |

you cant do it because it looks for an image, and dosnt find an image.
Its a function of the browser.
If the browser looks for an image and finds no image data or headers it displpays the red X.
You cant include image headers in the script because you need to send redirect headers. |
