allow an attacker to obtain a dump of the remote database.  PHP-Fusion
has the ability to create database backups and store them on the web
server, in the directory '/fusion_admin/db_backups/'.  Since there is no
access control on that directory, an attacker may guess the name of a
backup database and download it.");
