Vulnerability discussion

By default, InfoPath 2007 caches form templates when they are attached to a mail item that is recognized as an InfoPath e-mail form. When users fill out forms that open with a restricted security level, InfoPath uses the cached version of the mailed template, rather than any published version.To circumvent users filling out a published form, an attacker could e-mail an alternate version of the form, which would return the data to the sender as part of a phishing attack and could be used to gain access to confidential information.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
