Description
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.
