Rating: Less/Moderately critical
Impact: Spoofing
Where: From remote
======================================================================
3) Description of Vulnerabilities
Vulnerability "A":
It is possible for a inactive tab to spawn dialog boxes e.g. the
JavaScript "Prompt" box or the "Download dialog" box, even if the user
is browsing/viewing a completely different web site in another tab.
The problem is that the browsers does not indicate, which tab launched
the dialog boxes, which therefore could lead the user into disclosing
information to a malicious web site or to download and run a program,
which the user thought came from another trusted web site e.g. their
bank.
Demonstration:

Vulnerability "A" Affects:
Mozilla 1.7.3
Mozilla Firefox 0.10.1
Camino 0.8
Opera 7.54
Konqueror 3.2.2-6
Netscape 7.2
Avant Browser 9.02 build 101
Avant Browser 10.0 build 029
Maxthon (MyIE2) 1.1.039
Vulnerability "B":
It is possible for a inactive tab to always gain focus on a form field
in the inactive tab, even if the user is browsing/viewing a completely
different web site in another tab.
This is escalated a bit by the fact that most people do not look at
the monitor while typing data into a form field, and therefore might
send data to the site in the inactive tab, instead of the
intended/viewed tab.
Demonstration:

Vulnerability "B" Affects:
Mozilla 1.7.3
Mozilla Firefox 0.10.1
Netscape 7.2
