  The 'dir' command can be used to examine the filesystem of the machine and
  gather further information about the host by using relative directory listings
  (I.E. '../../../' or '\..\..\..').

  The 'delete' command can be used to delete any file on the server that the
  Platinum FTP server has permissions to.

  Issuing the command  'cd @/..@/..' will cause the
  Platinum FTP server to crash and consume all available CPU time on
  the server.");
