Information

Protection from zone elevation must be enabled in all Office programs.

GROUP ID: V-223304
RULE ID: SV-223304r960921

Internet Explorer places restrictions on each web page users can use the browser to open. Web pages on a user's local computer have the fewest security restrictions and reside in the Local Machine zone, making this security zone a prime target for malicious users and code. Disabling or not configuring this setting could allow pages in the Internet zone to navigate to pages in the Local Machine zone to then run code to elevate privileges. This could allow malicious code or users to become active on user computers or the network.

Solution

Set the policy value for

Computer Configuration >> Administrative Templates >> Microsoft Office 2016 (Machine) >> Security Settings >> IE Security >> Protection from Zone Elevation to 'Enabled'

and select the check boxes for all installed Office programs.
