    tftp

PROBLEM

    The  TFTP  (trivial  file  transfer  protocol)  service   provides
    remote  access  to  files,  without  asking  for a password. It is
    typically used for the initialization of diskless computers, of  X
    terminals, or of other dedicated hardware.

    When the TFTP  daemon does not  limit access to  specific files or
    hosts, a remote intruder can  use the service to obtain  copies of
    the  password  file  or  of  other  system  or  user  files, or to
    remotely overwrite files.
