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.

Insecure Storage: S3 Write Anonymous Access

Java/JSP

Abstract

La aplicación concede acceso anónimo de escritura a un objeto o contenedor de AWS S3.

Explanation

La concesión de acceso anónimo de escritura a un objeto o contenedor permite que los usuarios malintencionados reemplacen el contenido o que carguen contenido malintencionado.

Ejemplo 1: El siguiente código define una Access Control Policy que concede acceso anónimo de escritura al contenedor foo.


    GetBucketAclRequest bucketAclReq = GetBucketAclRequest.builder().bucket("foo").build();
    GetBucketAclResponse getAclRes = s3.getBucketAcl(bucketAclReq);
    List<Grant> grants = getAclRes.grants();

    Grantee allusers = Grantee.builder().uri("http://acs.amazonaws.com/groups/global/AllUsers").build();
    Permission fc_permission = Permission.fromValue("Write");
    Grant grant = Grant.builder().grantee(allusers).permission(fc_permission).build();
    grants.add(grant);

    AccessControlPolicy acl = AccessControlPolicy.builder().grants(grants).build();
