XSS Challenge I. October 17, 2016. November 3, 2018. Brute The Art of XSS Payload Building. Some weeks ago, a XSS challenge was launched: the goal was to pop an alert (1) box in latest Google Chrome at that time (version 53). Code was minified (made by just one continuous line) which always brings interesting possibilities to handle input. The reason of this problem is that you post some HTML tags to the server side, by default, asp.net will validate the posted content by the client to prevent XSS attack. For information about this, search ASP.NET MVC XSS, you'll find many results about this. For example: Preventing XSS Attacks in ASP.NET MVC using ValidateInput and AllowHTM In order to completely make your application armoured and protected against XSS, I would recommend using the ASP.NET's ValidateRequest filter along with a custom application-wide filter which encodes special characters in all requests. The application should not accept any script, special character or HTML in fields whenever not required
