  script_tag(name:"insight", value:"ftpd(8) is a general-purpose implementation of File Transfer Protocol (FTP)
server that is shipped with the FreeBSD base system.  It is not enabled
in default installations but can be enabled as either an inetd(8) server,
or a standard-alone server.

A cross-site request forgery attack is a type of malicious exploit that is
mainly targeted to a web browser, by tricking a user trusted by the site
into visiting a specially crafted URL, which in turn executes a command
which performs some privileged operations on behalf of the trusted user
on the victim site.

The ftpd(8) server splits long commands into several requests.  This
may result in the server executing a command which is hidden inside
another very long command.");
