Check: GEN003490

VMware ESX 3 Server: GEN003490 (in version v1 r2)

Title

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

Discussion

If the group owner of the at.deny file is not set to root, bin, sys, or cron, unauthorized users could be allowed to view or edit sensitive information contained within the file. Unauthorized modification could result in Denial-of-Service to authorized "at" users or provide unauthorized users with the ability to run "at" jobs.

Check Content

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

Fix Text

Change the group owner of the at.deny file to root, bin, sys, or cron. Procedure: # chgrp root at.deny
