Vulnerability discussion

Remote desktop session temporary folders must always be deleted after a session is over to prevent hard disk clutter and potential leakage of information. This setting controls the deletion of the temporary folders when the session is terminated.

Check content

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Policies\Microsoft\Windows NT\Terminal Services\ Value Name: DeleteTempDirsOnExit Type: REG_DWORD Value: 1

Fix text

Configure the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Temporary Folders -> "Do not delete temp folder upon exit" to "Disabled".

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
