Here’s the scenario:
We have users login on a secure connection. Could an unathorized user capture packets sent from the users machine to the server and then resend them? Would this allow them to login?
This is a homegrown login system running on coldfusion.
No.
Because the attacker in this scenario will still need to negotiate his own SSL handshake with the server, he will be unable to replay the victim’s packet verbatim.
