I actually found this at a log in screen, but it's on an obscure sub domain= =20 so I don't beleive that much cookie stealing can be done from it. Phishing, however, oh good lord yes. The phishing possbilities for this XSS= =20 vulnerability are immense (did I mention the site was SSL'd?). Anyway, I informed citibank through e-mail (no response), posted it on my= =20 blog (no response, no fix..) and now I'll post it here. I've had luck on FD in contacting BankOfAmerica employees in the past, so= =20 maybe there are a few Citibank admins listening? Let's hope so.
