Check: GEN002990

VMware ESX 3 Server: GEN002990 (in version v1 r2)

Title

The cron.allow file must not have an extended ACL. (Cat II impact)

Discussion

A cron.allow file that is readable and/or writable by other than root could allow potential intruders and malicious users to use the file contents to help discern information, such as who is allowed to execute cron programs, which could be harmful to overall system and network security.

Check Content

Check the permissions of the cron.allow file. # ls -l /etc/cron.allow If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the cron.allow file.
