Reino: Input Validation and Representation

Los problemas de validación y representación de entradas están causados por metacaracteres, codificaciones alternativas y representaciones numéricas. Los problemas de seguridad surgen de entradas en las que se confía. Estos problemas incluyen: «desbordamientos de búfer», ataques de «scripts de sitios», "SQL injection" y muchas otras acciones.

Denial of Service: Routing

Abstract
Un atacante podría manipular patrones de enrutamiento con comodines, abarcando efectivamente un amplio espectro de URL o incluso lograr coincidencias para todas las URL, lo que potencialmente podría resultar en el inicio de un ataque de denegación de servicio (DoS).
Explanation
La deficiencia surge de la integración de patrones de enrutamiento comodín a través del método routes.Ignore en aplicaciones ASP.NET. Este método permite que la entrada externa defina comportamientos de enrutamiento. Específicamente, el uso de comodines, como {*allaspx}, proporciona a los atacantes un punto de apoyo para manipular las acciones de enrutamiento. El problema central surge cuando la entrada que controla estos patrones comodín no se valida o desinfecta meticulosamente.
Los actores malintencionados pueden aprovechar esta deficiencia para orquestar un ataque DoS. Al proporcionar información que incorpora patrones de comodines demasiado permisivos, un atacante puede hacer que el sistema de enrutamiento ignore categorías importantes de solicitudes de URL. En el peor de los casos, el atacante podría proporcionar información que abarque todas las URL, lo que provocaría una denegación de servicio generalizada en la que la aplicación se volvería inaccesible.
