SV-25266r2_rule Remote Desktop Services must be configured to use session-specific temporary folders.

Vulnerability discussion

If a communal temporary folder is used for remote desktop sessions, it might be possible for users to access other users' temporary folders. If this setting is enabled, only one temporary folder is used for all remote desktop sessions. Per session temporary folders must be established.

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: PerSessionTempDir 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 use temporary folders per session” 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.
