Fastream NETFile FTP/Web Server HTTP HEAD DoS
------------------------------------------------------------------------
SUMMARY
" <http://www.fastream.com/netfileserver.htm>; Fastream NETFile FTP/Web
Server is a secure FTP server and Web-based file server combined together
in one program. Our claim is that it is the "easiest to setup and
administer server" on the Internet!"
Due to improper handling of keepalive in HTTP HEAD requests, it is
possible to cause a denial of service to Fastream NETFile FTP/Web Server.
DETAILS
Vulnerable Systems:
* Fastream NETFile FTP/Web Server 7.1.2 Professional
Fastream NETfile FTP/Web Server improperly handles the timeout on
"keepalive" connections after making a HEAD request to the web server.
When a remote user sends a HEAD request, the web server doesn't close the
connection with the client. This makes it possible for a remote user to
use all the available connections and thus make the software deny service
to other users.
