Title

The cron.deny file must not have an extended ACL. (Cat II impact)

Discussion

If there are excessive file permissions for the cron.deny file, sensitive information could be viewed or edited by unauthorized users.

Check Content

Check the permissions of the file. # ls -lL /etc/cron.deny 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/cron.deny
