默认情况下，ASP.NET MVC 4是否需要额外的XSS处理 [英] Does ASP.NET MVC 4 require extra XSS handling by default

问题描述

默认情况下，ASP.NET MVC 4忽略帖子消息中的HTML输入.如果我不明确接受HTML，我需要编写任何代码来保护自己的网站免受XSS攻击吗?我不会使用[AllowHtml]或[ValidateInput(false)].我只是想找出是否应该担心XSS攻击.我正在使用Razor作为视图引擎.

ASP.NET MVC 4 by default ignores HTML input in a post message. If I don't explicitly accept HTML, is there any code I need to write to defend my site against XSS attacks? I won't be using [AllowHtml] or [ValidateInput(false)]. I'm just trying to find out if I should worry about XSS attacks or not. I'm using Razor as my view engine.

我发现 Amir Ismail 一个解决您所有问题的方法. http://miroprocessordev.blogspot.com/2012/03/save-aspnet-mvc-application-against.html

I found an excellent blog post by Amir Ismail that addresses all of your concerns. http://miroprocessordev.blogspot.com/2012/03/save-aspnet-mvc-application-against.html

总结他写的东西. 除非使用Html.Raw，否则剃刀默认编码. Html.AntiForgeryToken()可用于创建随机令牌，以防止CSRF，但是它要求用户接受Cookie.

To summarize what he writes. Razor is encoded default unless Html.Raw is used. Html.AntiForgeryToken() can be used to create a random token that will protect against CSRF however it requires the user to accept cookies.
