287153 - Detect insecure fill-in/submission of SSNs

Status: RESOLVED EXPIRED

(Core :: DOM: Core & HTML, enhancement)

Description

[Ram Moskovitz]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1
Build Identifier: 

Warn the user when they type a number into an insecure form which looks like a
social security number if not submitting to a TLS/SSL protected site.

Rationale: this is another bit of anti-phishing bar-raising, and user protection.

If we check submitted values, it's possible that a page author may use
JavaScript to scramble the values before submission. So we may want to run the
checking code onblur, and warn the user at that point.

Very similar to https://bugzilla.mozilla.org/show_bug.cgi?id=287092


Reproducible: Always

Is this something you want as part of _Gecko_, or as part of the app?  The app
can already register as a form submit observer if it wishes....  And certainly
Gecko is not going to be running random onblur handlers on everything in sight.

Even typing your numbers into a dodgy site could be enough to have them
captured. You don't need a form submission. The site could send each character
to the server as it's typed using XMLHttpRequest. 

IMO, a better approach is for the browser to have a heuristic-based phishing
detector, and if it's suspicious of a site, disable all form controls until the
user has followed the procedure to dismiss the yellow bar and enable them.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
