Vulnerability: Open redirect

Vulnerability: Open redirect: ASP.NET MVC 5 Identity: Authentication and Authorization
Vulnerability: Open redirect: ASP.NET MVC 5 Identity: Authentication and Authorization

Sometimes it’s necessary to redirect from one controller to another within the application. There is no risk on doing that if no user input is involved in the process. But, as soon as any external data is used for the redirection, vulnerabilities may appear. To prevent yourself from these kinds of attacks, try to maximally avoid the usage of open redirects. But, if you have to really use them, make sure that you have a whitelist of sites that can be used for this purpose. Also, ASP.NET MVC 5 has built-in methods for identifying internal URLs via the URL helper object on the controller class. The solution in this experiment is to verify the redirect string with URL object’s IsLocalUrl method before performing the redirect.
