tag_summary = "According to its version number, the remote version of the Home Web Server is
  prone to a denial-of-service vulnerability because it fails to adequately
  handle malformed HTTP requests.

  Attackers can exploit this issue to cause the graphical interface of
  the server to stop responding, denying service to the administrator.

  Home Web Server 1.7.1.147 is vulnerable; other versions may also be
  affected.";
