Discussion

The Internet service daemon configuration files must be protected as malicious modification could cause Denial of Service or increase the attack surface of the system.

Check Content

Check the permissions of the xinetd configuration files. 

Procedure:
# ls -alL /etc/xinetd.conf
If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file.
# setfacl --remove-all /etc/xinetd.conf
