SV-32493r1_rule Remote Desktop Services will delete temporary folders when a session is terminated.

Vulnerability discussion

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

Check content

If the following registry value doesn’t exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Subkey: \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.
