Vulnerability discussion

This check verifies that file attachments are marked with their zone of origin allowing Windows to determine risk.

Check content

If the following registry value doesn’t exist or is not configured as specified, this is a finding: Registry Hive: HKEY_Current_User Subkey: \Software\Microsoft\Windows\CurrentVersion\Policies\Attachments\ Value Name: SaveZoneInformation Type: REG_DWORD Value: 2

Fix text

Configure the policy value for User Configuration -> Administrative Templates -> Windows Components -> Attachment Manager -> “Do not preserve zone information in file attachments” 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.
