The remote host is running WordPress BLOG, a web blog manager written
in PHP.

The remote version of this software is vulnerable to an HTTP-splitting attack
wherein an attacker can insert CR LF characters and then entice an unsuspecting
user into accessing the URL. The client will parse and possibly act on the
secondary header which was supplied by the attacker.

Solution : Upgrade to the latest version of this software
Risk factor : Medium";
