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.

Setting Manipulation: User-Controlled Allow List

Abstract
La aplicación permite a un usuario definir una lista de permitidos, lo que puede habilitarlo para marcar la entrada malintencionada como segura.
Explanation
Los marcos a menudo tienen listas blancas de validación para ofrecer protección contra vulnerabilidades.

Ejemplo 1: Lo siguiente permite a un usuario malintencionado configurar la lista de permitidos que utiliza AngularJS para determinar qué tipos de vínculos pueden recuperar las imágenes.

myModule.config(function($compileProvider){
    $compileProvider.imgSrcSanitizationWhitelist(userInput);
});


Esto puede parecer correcto, pero si el usuario establece la expresión regular en /^(http(s)?|javascript):.*/, la aplicación permitirá el uso de JavaScript en línea en las direcciones URL de origen de la imagen, lo que puede provocar ataques de scripts entre sitios.
Otras instancias de listas de permitidos pueden prevenir todos los diferentes tipos de ataques, especialmente ataques de Cross-Site Scripting, Command Injection y SQL Injection, junto con fallos en la lógica empresarial.
