VCENTER-000021 - The use of Linux-based clients must be restricted.

Information

Although SSL-based encryption is used to protect communication between client components and vCenter Server or ESXi, the Linux versions of these components do not perform certificate validation. Even if the self-signed certificates are replaced on vCenter and ESXi with legitimate certificates signed by the local root certificate authority or a third party, communications with Linux clients are still vulnerable to MiTM attacks.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Replace all Linux-based clients connecting to the vCenter Server with non-Linux-based clients.
