Re: Internet Explorer Phishing mouseover issue
The "http-equiv" and "Gandalf" examples are very similar, but I think
there might be some important distinctions.
1) The http-equiv example (CVE-2004-1104) uses a BASE tag with an href
attribute. In the form, the A tag has an "href=" without a value.
The value of the BASE HREF is displayed on the status bar when the
user does a mouseover.
2) The Gandalf example (CVE-2006-0799) does not have a base href at
all. But the A HREF has a value.
The value of the A href is displayed on the status bar when the
user does a mouseover.
3) If you use a hybrid of the two previous examples, in which both
BASE and A tags specify an href, then the A HREF is displayed on
the status bar when the user does a mouseover.
NOTE that the following difference does not seem to have an impact:
4) the http-equiv example has the A tag outside of the form, but the
Gandalf example has the A tag inside the form. Switching these
around doesn't seem to affect what gets displayed.
Both examples have the same problem in which the form's "action" step
is not displayed in the status bar, but as we see above, there are two
separate vectors with slightly different results.
This was tested in IE 6.0.2900.2180 on XP.
