When using ASP.net MVC the framework injects the current version that is running as a header in your response. This gives clients quite a overview of what version of MVC the server might be running, which allows malicious users to quite easily search for security vulnerabilities affecting the serving version of ASP.NET MVC.

It is recommended to disable this header to prevent any leaking of potential information that could aid a attacker.

How do I fix this ?

In your your Global.asax file on the root of your app, under the Application Start event add the following:

MvcHandler.DisableMvcResponseHeader = true;
