Check: GEN003255

VMware ESX 3 Server: GEN003255 (in version v1 r2)

Title

The at.deny file must not have an extended ACL. (Cat II impact)

Discussion

The "at" daemon control files restrict access to scheduled job manipulation and must be protected. Unauthorized modification of the at.deny file could result in Denial-of-Service to authorized "at" users or provide unauthorized users with the ability to run "at" jobs.

Check Content

Determine if the at.deny file has an extended ACL. # ls -l at.deny If the file's permissions contain a '+', the file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the at.deny file.
