Unauthenticated Command Execution (CVE-2016-6646)

based user interface that uses the AMF protocol to communicate with the 
server. There are 2 classes, GetSymmCmdRequest and RemoteServiceHandler, that
perform no input validation and require no authentication and may be leveraged
by an attacker to run arbitrary code on the system with root privileges.

CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

Authenticated Command Execution (CVE-2016-6645)

execution vulnerability. The vApp Manager runs on port 5480 and has a Flash 
based user interface that uses the AMF protocol to communicate with the 
server. There are 3 classes, GeneralCmdRequest, PersistantDataRequest and 
GetCommandExecRequest, that perform no input validation and may be leveraged 
by an authenticated attacker to run arbitrary code on the system with root 
privileges.

CVSS v3 Base Score: 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
