MVC 5 ASP.Net aplpication protect against HTTP Parameter pollution

In the scope of web security reviews, we got a security scan assessment result from our provider which mentions HPP (Http Parameter Polution) as a vulnerability in the application. In our case, we are building a MVC5 application and i would like to have some advices on how to fix this. I know, it is about validating and checking the URL, but it would be great if i get a solution example. I want to centralize it in the application. Many thanks for your help.
