Hinduism isn't very concerned with imposing laws on people. It offers advice and guidelines, teaching us how to live a good life, how to bring about positive outcomes based on fundamental truths, but then leaves people to decide what to do. The idea is that we learn from mistakes and become better, wiser individuals in the future...even though that generally means it can take multiple life times to gain such advancement.
Adultery is considered very bad in Hinduism. We are taught that it can destroy the family unit. It is advised that people do not have sex outside of marriage.
We are not taught to punish one another. However we are taught about Karma. If we cause misery to another, misery will come back to us. If we bring joy, we receive joy. Therefore cheating our spouse will inevitably bring negative consequences, whether immediate or sometime later. However if someone were to, for example, beat or kill a person for committing adultery, they too would eventually receive negative karma for their act of violence.
