Description
An attacker might target InfoPath 2003 forms to try and compromise an organization's security. InfoPath 2003 did not write a published location for email forms, which means forms could open without a corresponding published location. By default, InfoPath sends all forms via email using InfoPath email forms integration, including forms created using the InfoPath 2003 file format.
