  - It is possible to inject malicious script through the DHCP HOSTNAME option. The malicious script
  code is injected into the device's `DHCP Monitor` page (System->Monitor->DHCP Monitor) on the
  web-based interface which is accessible by the webui administrators.

  - The FortiOS webui accepts a user-controlled input that specifies a link to an external site, and
  uses that link in a redirect. The redirect input parameter is also prone to a cross site scripting.");
