Secure-site spoof (requires security warning dialog)


Tristor reports that it was possible to spoof the browser's secure-site
indicators (the lock icon, the site name in the URL field, the gold URL
field background in Firefox) by first loading the target secure site in a
pop-up window, then changing its location to a different site.

If the user has turned on the "Entering secure site" modal warning dialog
then the window location can be changed while that dialog is displayed and
the secure-browsing indicators from the original site will remain.

These dialogs are turned off by default in Firefox, and most Suite users
click the checkbox to turn them off.

Workaround

Turn  off the "Entering encrypted site" warning dialog if you have not
already.
