Check: GEN002990

AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN002990 (in versions v1 r14 through v1 r10)

Title

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

Discussion

A cron.allow file that is readable and/or writable by other than root could allow potential intruders and malicious users to use the file contents to help discern information, such as who is allowed to execute cron programs, which could be harmful to overall system and network security.

Check Content

Check the permissions of the cron.allow file. #aclget /var/adm/cron/cron.allow Verify if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix Text

Remove the extended ACL from the cron.allow file and disable extended permissions. #acledit /var/adm/cron/cron.allow
