That does not necessarily require TLS to mitigate (although TLS does help, anyways). There are other issues with financial transactions, whether or not TLS is used. (I had idea, and wrote a draft specification of, "computer payment file", to try to improve security of financial transactions and avoid some kinds of dishonesty; it has its own security and does not require TLS (nor does it require any specific protocol), although using TLS with this is still helpful.) (There are potentially other ways to mitigate the problems as well, but this is one way that I think would be helpful.)
