Is it possible for a remote user who is accessing a Terminal Server via RDP to have virus/spyware from their local computer infect the server they are logging into or have virus/spyware from the Terminal Server they are logged into infect their local PC? Assume there are no shared drives/mapped drives in the TS session. I know that while they are in their terminal session they could download 'bad' stuff and it could infect the server if not trapped. As well I know they could minimize their terminal session and go out to the Internet directly through their PC and get the local PC infected. But can any virus/spyware jump from either the local desktop to the remote desktop or vice versa during a terminal session?
