Reino: Security Features

La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Access Control: ACL Manipulation

Java/JSP

Abstract

La aplicación permite que un usuario malintencionado manipule la política de control de acceso (ACP) de un objeto o contenedor de AWS S3

Explanation

La aplicación permite que un usuario malintencionado controle los permisos concedidos a un objeto o contenedor de AWS S3. El usuario malintencionado puede así definir una política débil que le permita leer el contenido o escribir en archivos arbitrarios.

Ejemplo 1: El siguiente código crea un nuevo contenedor mediante una política de control de acceso especificada por el usuario.



    String canned_acl = request.getParameter("acl");

    CreateBucketRequest createBucketRequest = CreateBucketRequest.builder()
        .bucket("foo")
        .acl(canned_acl)
        .createBucketConfiguration(CreateBucketConfiguration.builder().locationConstraint(region.id()).build())
        .build();

Incluso si la aplicación espera que se seleccione el parámetro acl en un grupo limitado, un usuario malintencionado puede definirlo como public-read-write y conceder acceso anónimo completo al contenedor.
