Check: GEN003410

VMware ESX 3 Server: GEN003410 (in version v1 r2)

Title

The "at" directory must not have an extended ACL. (Cat II impact)

Discussion

If the "at" directory has an extended ACL, unauthorized users could be allowed to view or to edit files containing sensitive information within the "at" directory. Unauthorized modifications could result in Denial-of-Service to authorized "at" jobs.

Check Content

Check the permissions of the file. # ls -lLd /var/spool/cron/atjobs /var/spool/atjobs If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the "at" directory.
