Title

Disabling email forms from the Internet Security Zone must be configured. (Cat II impact)

Discussion

InfoPath e-mail forms can be designed by an external attacker and sent over the Internet as part of a phishing attempt. Users might fill out such forms and provide sensitive information to the attacker. By default, forms that originate from the Internet can be opened, although those forms cannot access content stored in a different domain.
