Discussion

If TFTP runs with the setuid or setgid bit set, it may be able to write to any file or directory and may seriously impair system integrity, confidentiality, and availability.

Check Content

Check the mode of the TFTP daemon.

Procedure:
# grep "server " /etc/xinetd.d/tftp
# ls -lL <in.tftpd binary> 

If the mode of the file is more permissive than 0755, this is a finding.

Fix Text

Change the mode of the TFTP daemon.

Procedure:
# chmod 0755 <in.tftpd binary>
