Vulnerabilidades de Cross-Site Scripting (XSS) son algunas de las vulnerabilidades más comunes en Internet, y han aparecido como respuesta directa a la creciente cantidad de interacción de los usuarios en las aplicaciones web actuales.
En esencia, un ataque XSS funciona aprovechando el hecho de que las aplicaciones web ejecutan scripts en los navegadores de los usuarios. Cualquier tipo de script creado dinámicamente que se ejecute pone en peligro una aplicación web si el script que se ejecuta puede ser contaminado o modificado de alguna manera, en particular por un usuario final.
Los ataques XXS se clasifican de varias maneras, siendo las tres principales:
