Upgrade Your WordPress
A new WP exploit has been reported- and a new release (2.6.5) issued to address it:
“The system does not properly filter HTML code from user-supplied input in the ‘HTTP_HOST’ header parameter before displaying the input. A remote user can submit a specially value to cause arbitrary scripting code to be executed by the target user’s browser. The code will originate from the site running the WordPress software and will run in the security context of that site. As a result, the code will be able to access the target user’s cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
The vulnerability resides in ‘wp-includes/feed.php’ and ‘wp-includes/version.php’.
Only systems running on IP-based virtual servers with Apache 2.x are affected.
Jeremias Reith reported this vulnerability.
Impact: A remote user can access the target user’s cookies (including authentication cookies), if any, associated with the site running the WordPress software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.”
Recommend that you upgrade your installations of WP.
