- 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
