ASP.NET MVC Bad Practices: Form Without AntiForgery Token
Abstract
La vista de Razor contiene un formulario, pero no incluye un token antifalsificación con ese formulario y, por tanto, puede ser más susceptible a la falsificación de solicitud entre sitios.
Explanation
ASP.NET MVC es un método fácil para proteger mejor las aplicaciones contra la falsificación de solicitud entre sitios, ya que agrega un token antifalsificación en el formulario HTML y valida dicho token antifalsificación en el controlador. Si se usa, este token suele estar incluido como campo de formulario oculto y se valida cuando se envía el formulario, lo que hace que aumenten las probabilidades de que una solicitud proceda de la aplicación y no sea una falsificación.
Por lo general, el programador deberá incluir este token antifalsificación porque aumenta el coste de los scripts malintencionados en relación con una aplicación.
Ejemplo 1:El siguiente código de Razor crea un formulario en el HTML resultante sin la defensa integrada contra la falsificación de solicitudes entre sitios:

Ejemplo 1:El siguiente código de Razor crea un formulario en el HTML resultante sin la defensa integrada contra la falsificación de solicitudes entre sitios:
Example 2::The following Razor code creates a form in the resulting HTML without the built-in defense against cross-site request forgery. Note that parameter
@using (Html.BeginForm(new { ReturnUrl = ViewBag.ReturnUrl })) {
// ... form elements
}
antiforgery
is set to either false
or null
:
@using (Html.BeginForm("actionName", "controllerName", routeValues, FormMethod.Post, antiforgery: false, htmlAtts)) {
// ... form elements
}
