WordPress 'xmlrpc.php' pingback.ping Server-Side Request Forgery

Medium Nessus Plugin ID 64453

Synopsis

The remote web server contains a PHP application that is affected by a
server-side request forgery vulnerability.

Description

The WordPress install hosted on the remote web server is affected by a
server-side request forgery vulnerability because the 'pingback.ping'
method used in 'xmlrpc.php' fails to properly validate source URIs
(Uniform Resource Identifiers). A remote, unauthenticated attacker can
exploit this issue to disclose sensitive information and conduct
remote port scanning against a remote host.

Solution

Upgrade to WordPress 3.5.1 or later.
