Check: GEN005770

VMware ESX 3 Server: GEN005770 (in version v1 r2)

Title

The NFS exports configuration file must not have an extended ACL. (Cat III impact)

Discussion

File system extended ACLs provide access to files beyond what is allowed by the mode numbers of the files. Excessive permissions on the NFS export configuration file could allow unauthorized modification of the file, which could result in Denial-of-Service to authorized NFS exports and the creation of additional unauthorized exports.

Check Content

Determine if the NFS exports configuration file has an extended ACL. If it does, this is a finding.

Fix Text

Remove the extended ACL from the NFS export configuration file.
