VMware ESX 3 Server: GEN003245 (in version v1 r2)

Title

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

Discussion

File system extended ACLs provide access to files beyond what is allowed by the mode numbers of the files. Unauthorized modification of the at.allow file could result in Denial-of-Service to authorized "at" users and the granting of the ability to run "at" jobs to unauthorized users.

Check Content

Determine if the at.allow file has an extended ACL. If it does, this is a finding.

Fix Text

Remove the extended ACL from the at.allow file.
