In a server room with KVMs, all of the computers would be logged off and locked.It stems from Network Level Authentication (NLA), which is a feature that you can use to protect Windows installations that have the Remote Desktop Protocol (RDP) enabled.NLA stops anyone from remotely logging into the Windows computer by requiring them to authenticate first.Now, the authentication mechanism caches the clients login credentials on the RDP host so that it can quickly log the client in again if it loses connectivity.
The change enables an attacker to circumvent a Windows lock screen, warns CERTCC, which disclosed the issue, in an advisory. Then, you lock that remote desktop to stop an attacker from accessing it from your machine while you leave the room. This means that the remote system unlocks without requiring any credentials to be manually entered. Duo Security admits that its MFA products are affected, adding that the issue isnt its fault. We use a unique technology which allows us to enforce MFA on top of the authentication protocol itself (e.g. What you are observing is Windows Server 2019 honoring Network Level Authentication (NLA). Network Level Authentication requires user creds to allow connection to proceed in the earliest phase of connection. Those same creds are used logging the user into a session (or reconnecting). As long as it is connected, the client will cache the credentials used for connecting and reuse them when it needs to auto-reconnect (so it can bypass NLA). Microsoft doesnt plan to change this behavior, so do not use the Lock feature over RDP. Log out when done or away pic.twitter.comfevq4LvA3V Will Dormann (wdormann) June 4, 2019. You can also disconnect RDP sessions when you go and visit the loo. Windows Ce 6 0 Rdp Client Intosh Windows 10 And WindowsFor one thing, this unexpected behavior only exists on Windows 10 and Windows Server 2019. I, for one, have done that, under the theory that the server is the important one and it should be locked, rather than the one that Im sitting at. Having a security feature disabled, even though the condition may not come up often, seems to me to be the wrong way to treat security. Even if I tell the remoteapp server to lock, all you would have to do is close the session and double click the shortcut and it has my credentials cached. Youve got much larger problems than your RDP session if youre leaving your local computer unlocked.

I can do a lot more with all of your passwords than I could with access to your remote session. ![]()
