AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN003410 (in versions v1 r14 through v1 r10)

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 file. #aclget /var/spool/cron/atjobs Verify if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix Text

Remove the extended ACL from the at directory and disable extended permissions. #acledit /var/spool/cron/atjobs
