ASP.NET Misconfiguration: Header Checking Disabled

Abstract
Al deshabilitar la comprobación de encabezados se abre la puerta a los atacantes para que realicen ataques de manipulación de los encabezados.
Explanation
De forma predeterminada, .NET Framework impide el envío de nuevos caracteres a API que definen valores de encabezado HTTP. No obstante, este comportamiento se puede deshabilitar mediante programación configurando la propiedad EnableHeaderChecking en el objeto HttpRuntimeSection como false.

Ejemplo 1: El código siguiente deshabilita la comprobación de encabezados.

Configuration config = WebConfigurationManager.OpenWebConfiguration("/MyApp");
HttpRuntimeSection hrs = (HttpRuntimeSection) config.GetSection("system.web/httpRuntime");
hrs.EnableHeaderChecking = false;


Cuando se deshabilita esta comprobación, el código que permite las entradas de usuario para llegar a las API de configuración de encabezados es vulnerable a ataques como la división de respuesta de HTTP.
