Reino: Encapsulation
La encapsulación consiste en crear límites fuertes. En un explorador web esto puede suponer la seguridad de que tu codificación móvil no se vea comprometido por otro código móvil. En el servidor puede significar la diferenciación entre los datos validados y los que no lo están, entre los datos de un usuario y los de otro, o entre los diferentes usuarios, los datos que pueden ver y los que no.
Cross-Site Scripting: Untrusted HTML Downloads
Abstract
Deshabilitar el encabezado
X-Download-Options que se define como noopen permite que las páginas HTML descargadas se ejecuten en el contexto de seguridad del sitio que las proporciona.Explanation
Cuando los sitios deben proporcionar descargas a los usuarios, la opción para abrirlos indica que los archivos proporcionados que se ejecuten en el explorador se podrán abrir en el explorador actual en el mismo contexto de seguridad que el sitio.
Si un atacante consigue manipular los archivos descargados, podrá insertar HTML o scripts que se ejecutan en el explorador para que actúen como ataques de Cross-Site Scripting y roben o manipulen información en la sesión actual.
Ejemplo 1: El siguiente ejemplo deshabilita de forma explícita las protecciones frente a las descargas proporcionadas que se ejecutan en el explorador:
