The remote host is using the PT News management system.

There is a flaw in this version which allows anyone to execute 
arbitrary admnistrative PTnews command on this host (such as deleting
news or editing a news) without having to know the administrator
password.

An attacker may use this flaw to edit the content of this website
or even to delete it completely.

Solution : Upgrade to PT News 1.7.8 or newer
Risk factor : High";
