VMware vCenter / vRealize Orchestrator 4.2.x / 5.x / 6.x Java Object Deserialization RCE (VMSA-2015-0009)

Synopsis :

The remote host has a virtualization application installed that is
affected by a remote code execution vulnerability.

Description :

The version of VMware vCenter / vRealize Orchestrator installed on the
remote host is 4.2.x, 5.x, or 6.x and includes the Apache Commons
Collections (ACC) library version 3.2.1. It is, therefore, affected by
a remote code execution vulnerability due to unsafe deserialize calls
of unauthenticated Java objects to the ACC library. An
unauthenticated, remote attacker can exploit this, by sending a
crafted request, to execute arbitrary code on the target host.
