Description
InfoPath makes it possible to host InfoPath forms in other applications as ActiveX controls. Such controls are known as InfoPath form controls. A malicious user could insert a Web beacon into one of these controls which could 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 form controls warn users about potential Web beaconing threats.
