Title
Cron and crontab directories must not have extended ACLs. (Cat II impact)
Discussion
To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured. ACLs on cron and crontab directories may provide unauthorized access to these directories. Unauthorized modifications to these directories or their contents may result in the addition of unauthorized cron jobs or deny service to authorized cron jobs.
Check Content
Check the permissions of the crontab directories. # ls -ld /var/spool/cron/crontabs/ If the permissions include a "+", the directory has an extended ACL and this is a finding.
Fix Text
Remove the extended ACL from the directory. # getfacl [crontab directory] Remove each ACE returned. # setfacl -d [ACE] [crontab directory]
