//                                  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']);
$message = preg_replace("/>/","&gt;",$_POST['message']);
$message = preg_replace("/</","&lt;",$_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);
$message = preg_replace("/>/","&gt;",$message);
$message = preg_replace("/</","&lt;",$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*

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
