Reino: API Abuse

Un API es un contrato entre un autor de llamada y un receptor de llamada. Las formas de abuso de API más comunes los produce el autor de llamada cuando no consigue atender su fin de este contrato. Por ejemplo, si un programa no consigue llamar chdir() después de llamar chroot(), se viola el contrato que especifica cómo cambiar el directorio de origen activo de una forma segura. Otro buen ejemplo de un abuso de manual es esperar que el receptor devuelva una información de DNS de confianza al autor de llamada. En este caso, el autor de llamada abusa el API del receptor haciendo determinadas suposiciones sobre su comportamiento (que el valor de retorno se puede usar con fines de autenticación). También se puede violar el contrato entre el autor de llamada y el receptor desde el otro lado. Por ejemplo, si un codificador envía SecureRandom y devuelve un valor no aleatorio, se viola el contrato.

ASP.NET Middleware Out of Order: Default Cookie Configuration

C#/VB.NET/ASP.NET

Abstract

La aplicación especifica incorrectamente el middleware de la política de cookies de ASP.NET.

Explanation

El middleware ASP.NET Core que no se agrega a la canalización de middleware en el orden correcto no funcionará según lo previsto, dejando la aplicación expuesta a una variedad de problemas de seguridad.

Ejemplo 1: El método UseCookiePolicy() agrega el middleware de política de cookies a la canalización de middleware, lo que permite políticas de cookies personalizadas. Cuando se especifica en el orden incorrecto, como se muestra, se ignorará cualquier política de cookies establecida por el programador.


...
var builder = WebApplication.CreateBuilder(...);
var app = builder.Build(...);
app.UseStaticFiles();
app.UseRouting();
app.UseSession();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    ...
}

app.UseCookiePolicy();
...
