Installing a plug in for Wordpress XML-RPC ping back

Description

In the XMLRPC module of any Wordpress installation, the pingback feature is enabled. This feature allows an attacker to send request to a vulnerable Wordpress site and use it to attack other websites. In other words, your Wordpress installation could be used in a Distributed Denial-of-Service (DDoS) attack without your knowledge.

The Fix

Wordpress has not released a fix for this problem, but there is a Wordpress plugin that will disable the pingback query (pingback.ping) from the XMLRPC module.

Note: The plugin needs to be installed on each Wordpress installation.
