DTOO164 - Beaconing UI shown for opened forms must be configured.
Malicious users can create InfoPath forms with embedded Web beacons that can be used to contact an external server when the user opens the form. Information could be gathered by the form, or information entered by users could be sent to an external server and cause them to be vulnerable to additional attacks. By default, InfoPath warns users about potential Web beaconing threats.
Set the policy value for User Configuration -> Administrative Templates -> Microsoft InfoPath 2013 -> Security -> 'Beaconing UI for forms opened in InfoPath' to 'Enabled (Always show beaconing UI)'.
