FileTransfer : a non-logged user can access system drives !

Post by UltraSam »

That's right. A user that connects to the server and that is not logged in windows (then not Windows-authentified) can still access the server file system with full read/write access...

That's why we've added the possibility to forbid the FileTransfer in the WinVNC property page: "Enable File Transfer" option.

1. By default, always disable the FileTransfer
2. When you connect with UltraVNC viewer, login Windows then go to WinVNC properties and Enable FileTransfer (if you plan to do some FT, of course...)
3. Before disconnecting Ultr@VNC, first Disable FileTransfer again.

Note: in this case, it is recommended to use the "When last client disconnects - Logoff Worstation" option. This way you don't have to think about Loggoff before disconnecting.
