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 with the following command:
$ sudo systemctl edit tftp.service

In the editor enter:
[Service]
ExecStart=/usr/sbin/in.tftpd -s /var/lib/tftpboot

After making changes, reload the systemd daemon and restart the TFTP service as follows:
$ sudo systemctl daemon-reload
$ sudo systemctl restart tftp.service
