Thanks Steve.
This proves the value of Full Disclosure.
This seems to have changed within a few hours of my posting to Full
Disclosure rather than in the several weeks after I first alerted it.
Note that Wachovia still has not subsequently contacted me to thank me,
acknowledge my work, or to threaten me.
Yes, the page that consumers can get to by navigating Wachovia's web site
(or in response to the paper mail Wachovia sent out) now is the
following, which posts using https to provide strong encryption:
https://www.wachovia.com/personal/forms/privacy_optout
It has comments with time-stamps of late yesterday, after I disclosed
on the list:

I do note that the existing URL:
http://www.wachovia.com/personal/forms/privacy_optout
still exists and is accessible.
That http page still appears to post the SSN, etc. unencrypted.
Clearly, someone needs to delete the old page or only allow it as https.
Of course, this is a very minor issue as there is no way for a consumer
trip over this page accidentally.
I wonder if Wachovia will follow the California state breach security
policy.

Subject: [Full-disclosure] Wachovia Bank website sends confidential
information
Wachovia Bank website sends confidential information (social security
numbers, phone number, address, etc.) over the Internet without encryption.
Horizon Network Security Security Advisory 07/10/2007
http://VerySecureLinux.com/ Jul 10, 2007
I. BACKGROUND
Wachovia Bank's official web site offers the following URL to allow its
customers to change their privacy preferences:
http://www.wachovia.com/privacy
Wachovia also notified its customers by U.S. Mail that they can use that
same URL besides.
That URL has a link to the following to actually change one's
preferences:
http://www.wachovia.com/personal/forms/privacy_optout
Unfortunately, that page appears to be an ordinary HTML form whose filled
out data then is transmitted via the post method to an http (not https)
URL.
III. ANALYSIS
We inspected the page's source via our Opera browser. (We did not sniff the
web traffic so we are not absolutely sure that there is not some hidden
encryption method, though there appears to be none.)
IV. DETECTION
It is trivial to inspect the page source or sniff the data to demonstrate
the problem. The problem has not been corrected.
V. WORKAROUND
Use a method other than their web site to exercise one's preferences.
VI. VENDOR RESPONSE
The vendor (Wachovia Bank) was notified via their customer service phone
number on June 25. We were transferred to web support. The person
answering asked us to FAX the details to her and we did so, also on June 25.
We explained that we were reporting a severe security problem on their web
site.
We stated that that if we did not hear back from them within 7 days and the
problem was not fixed by then that we would post the problem on the Full
Disclosure list, following accepted industry practice.
To date we have received no response and the problem remains unfixed.
VII. CVE INFORMATION
There is no CVE number.
VIII. DISCLOSURE TIMELINE
