// 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

$n_topic["email"]=$email;

$n_topic["title"]=$title;

$n_topic["date"]=$date;

$n_topic["ldate"]=$date;

$n_topic["name"]=htmlentities($name, ENT_QUOTES);

$n_topic["email"]=htmlentities($email, ENT_QUOTES);

$n_topic["title"]=htmlentities($title, ENT_QUOTES);
