Description

Druva inSync client for Windows exposes a network service on TCP
port 6064 on the local network interface. inSync versions 6.6.3
and prior do not properly validate user-supplied program paths
in RPC type 5 messages, allowing execution of arbitrary commands
as SYSTEM.

This module has been tested successfully on inSync versions
6.5.2r99097 and 6.6.3r102156 on Windows 7 SP1 (x64).
