Once the user arrives at the fake site they are usually prompted to enter personal information, and then that personal information can be used by the attacker in a variety of bad ways.

This is an RCE vulnerability in OpenSSL and all versions are technically vulnerable. However this is more of a concern with SSL VPN protocols than with HTTPS.
