Details

Malicious users could send e-mail InfoPath forms with embedded Web beacons that can be used to track when recipients open the form and provide confirmation that recipients’ e-mail addresses are valid. Additional information gathered by the form or information entered by users could also be sent to an external server and leave the users vulnerable to additional attacks. By default, InfoPath users are only warned of a beaconing threat if the form originates from the Internet.

Solution

Set the policy value for User Configuration -> Administrative Templates -> Microsoft InfoPath 2010 -> Miscellaneous ‘Email Forms Beaconing UI’ to ‘Enabled (Always show UI)’.
