Title

The "at" directory must not have an extended ACL. (Cat II impact)

Discussion

If the "at" directory has an extended ACL, unauthorized users could be allowed to view or to edit files containing sensitive information within the "at" directory. Unauthorized modifications could result in Denial of Service to authorized "at" jobs.

Check Content

Check the permissions of the directory. # ls -lLdD /var/spool/cron/atjobs If the directory has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the file. # chmod A- /var/spool/cron/atjobs
