AIX7-00-002149 - The AIX /var/spool/cron/atjobs directory must have a mode of 0640 or less permissive.

Information

Incorrect permissions of the /var/spool/cron/atjobs directory could permit unauthorized users the ability to alter atjobs and run automated jobs as privileged users. Failure to set proper permissions of the /var/spool/cron/atjobs directory provides unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.

Solution

Change the mode of the /var/spool/cron/atjobs directory:
# chmod 640 /var/spool/cron/atjobs
