WordPress < 2.3.3 XML-RPC Unauthenticated Post Modification

Medium

Synopsis

The remote host is vulnerable to a flaw that allows for unauthorized access to data.

Description

The version of WordPress installed on the remote host is vulnerable to an unauthorized access attack. An attacker exploiting this flaw would need the ability to authenticate as a valid user. Upon authentication, the user would be able to manipulate data sent to the 'xmlrpc.php' script which would allow for editing of other user posts.

Solution

Upgrade to WordPress 2.3.3, or later.
