Re: Firefox 2.0.0.6 Remote Variable Leakage vulnerability

Any sensitive data being leaked? A browser giving away
its properties to a script should not be termed
vulnerability.

Is it causing any of these...

1.) Loss of confidentiality
2.) Loss of integrity
3.) Loss of availability

Firefox Remote Variable Leakage

It is possible to read all variables that are set
inside Firefox.
That's right: ALL variables and registered objects
that are present
inside Javascript files and on runtime. It's even
possible to call
certain functions. That ranges from local Mozilla
config files to all
extensions registered inside Firefox. The example
below will show you
a list of a couple variables that were set. Note: it
is possible to
actively scan variables and hijack them when you
need to. I've tested
this against my own Firefox extension called: Fire
Encrypter. And I
was able to steal a dynamically generated password
successfully.
