Trivial File Transfer Protocol (TFTP) is a simple file transfer protocol, typically used to automatically transfer configuration or boot machines from a boot server. The packages tftp and atftp are both used to define and support a TFTP server.
Rationale:
TFTP does not support authentication nor does it ensure the confidentiality or integrity of data. It is recommended that TFTP be removed, unless there is a specific need for TFTP. In that case, extreme caution must be used when configuring the services.
Fix:
Remove or comment out any tftp lines in /etc/inetd.conf:
#tftp stream tcp nowait root internal
Parameter:
[no/yes]
Technical Mechanism:
Remove or comment out any tftp lines in /etc/inetd.conf:
#tftp stream tcp nowait root internal
