VMware vCenter Server Appliance BlazeDS AMF3 RCE (VMSA-2017-0007)
High Nessus Plugin ID 99474
A virtualization appliance installed on the remote host is affected by a remote code execution vulnerability.
The version of VMware vCenter Server Appliance installed on the remote host is 6.0 prior to Update 3b or 6.5 prior to Update c. It is, therefore, affected by a flaw in FlexBlazeDS when processing AMF3 messages due to allowing the instantiation of arbitrary classes when deserializing objects. An unauthenticated, remote attacker can exploit this, by sending a specially crafted Java object, to execute arbitrary code.
Upgrade to VMware vCenter Server Appliance 6.0 Update 3b / 6.5 Update c or later. Alternatively, apply the vendor-supplied workaround.
