// XSS in shoutbox //
//----------------------------------------------------------------------
--------//
Self explanitory... in the message body put: <script>alert('hi')</script>
Error: module/shout/jafshout.php
Line: 168 - 202
187 - 191 {
$message = preg_replace('/"/','',$_POST['message']);
$message = preg_replace("/>/",">",$_POST['message']);
$message = preg_replace("/</","<",$_POST['message']);
$message = str_replace("onmouse","",$_POST['message']);
$message = str_replace("//","edited",$_POST['message']);
}
change the relevent lines to look like the following, bar the first $_POST['message'].
187 - 191 {
$message = preg_replace('/"/','',$message);
$message = preg_replace("/>/",">",$message);
$message = preg_replace("/</","<",$message);
$message = str_replace("onmouse","",$message);
$message = str_replace("//","edited",$message);
}
etc etc.
*note*
This should be implemented on all of the variables stored to the flat-file
module/files/shout
*end note*

// PHP execution //

Yet again in the shoutbox type something like:
Windoze) <?php system(dir); ?>
Linux) <?php system(ls -la); ?>
you could see how usefull this could be ;) possably overwright admin/data_inc.php
(where the admin's password hash is) :p
