VMware ESX 3 Server: GEN003270 (in version v1 r2)

Title

The cron.deny file must be group-owned by root, bin, sys, or cron. (Cat II impact)

Discussion

Cron daemon control files restrict the scheduling of automated tasks and must be protected. Unauthorized modification of the cron.deny file could result in Denial-of-Service to authorized cron users or could provide unauthorized users with the ability to run cron jobs.

Check Content

Determine the cron.deny file's group owner. Procedure: # ls -lL cron.deny If the file is not group-owned by root, bin, sys, or cron, this is a finding.

Fix Text

Change the group owner of the cron.deny file to root, sys, bin, or cron. Procedure: # chown root /var/adm/cron/cron.deny
