RHEL-08-040350 - If the Trivial File Transfer Protocol (TFTP) server is required, the RHEL 8 TFTP daemon must be configured to operate in secure mode.

Information

Restricting TFTP to a specific directory prevents remote users from copying, transferring, or overwriting system files.

Solution

Configure the TFTP daemon to operate in secure mode by adding the following line to '/etc/xinetd.d/tftp' (or modify the line to have the required value):

server_args = -s /var/lib/tftpboot
