Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-17611	DTOO176 - InfoPath	SV-33651r1_rule	ECSC-1	Medium

Description
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.
