Vulnerability Discussion

If the group owner of the "cron.allow" file is not set to root, sensitive information could be viewed or edited by unauthorized users.

Check

Verify that the "cron.allow" file is group-owned by root.

Check the group owner of the "cron.allow" file with the following command:

# ls -al /etc/cron.allow
-rw------- 1 root root 6 Mar 5 2011 /etc/cron.allow

If the "cron.allow" file exists and has a group owner other than root, this is a finding.

Fix

Set the group owner on the "/etc/cron.allow" file to root with the following command:

# chgrp root /etc/cron.allow
