The TFTP daemon must operate in "secure mode" which provides access only to a single directory on the host file system.

Description
Secure mode limits TFTP requests to a specific directory. If TFTP is not running in secure mode, it may be able to write to any file or directory and may seriously impair system integrity, confidentiality, and availability.

Check Text ( C-36593r1_chk )
Determine if the TFTP daemon is installed, started, and running in secure mode. # cat /etc/inetd.conf | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v "^#" | cut -f 6,7 -d " " | grep -i tftp If the tftpd process is not configured with exactly one path argument (example: "/usr/lbin/tftpd tftpd"), this is a finding.

Fix Text (F-31960r1_fix)
Edit /etc/inetd.conf and add one path argument, representing the TFTP root directory, to the tftpd command.
