Firefox seems to have trouble with defining the proper hostname when requesting a ssl connection. I was able to trick Firefox in thinking the hostname behind the at-sign is legit and the same as the URI that requested an ssl connection, and this without a warning. PoC: https://www.gmail.com%C0%AF%C0%AF%C0%C0%80 () roguehost com You can add as much garbage between .com and the @ sign. So what else can we do? PoC: www.cnn.com%C0%AF%C0%AF%C0%C0%80@google www.gmail.com%C0%AF%C0%AF%C0%C0%80@hotmail ah heck we don't need that at all: www.gmail.comxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@hotmail works fine also :) _______________________________________________ Full-Disclosure - We believe in it.
