XSRF/CSRF Prevention in ASP.NET MVC and Web Pages By Rick Anderson
Cross-site request forgery (also known as XSRF or CSRF) is an attack against web-hosted applications whereby a malicious web site can influence the interaction between a client browser and a web site trusted by that browser. These attacks are made possible because web browsers will send authentication tokens automatically with every request to a web site. The canonical example is an authentication cookie, such as ASP.NET’s Forms Authentication ticket. However, web sites which use any persistent authentication mechanism (such as Windows Authentication, Basic, and so forth) can be targeted by these attacks.
