Access Control: ACL Manipulation
Abstract
O aplicativo permite que um invasor manipule a Access Control Policy (ACP) de um bucket ou objeto AWS S3.
Explanation
O aplicativo permite que um invasor controle as permissões concedidas a um bucket ou objeto do AWS S3. Isso permite que o invasor defina uma política fraca que possa permitir que eles leiam o conteúdo ou escrevam arquivos arbitrários.
Exemplo 1: O código a seguir cria um novo bucket usando uma Access Control Policy especificada pelo usuário.
Mesmo que o aplicativo espere que o parâmetro
Exemplo 1: O código a seguir cria um novo bucket usando uma Access Control Policy especificada pelo usuário.
String canned_acl = request.getParameter("acl");
CreateBucketRequest createBucketRequest = CreateBucketRequest.builder()
.bucket("foo")
.acl(canned_acl)
.createBucketConfiguration(CreateBucketConfiguration.builder().locationConstraint(region.id()).build())
.build();
Mesmo que o aplicativo espere que o parâmetro
acl
seja selecionado em um conjunto limitado, um invasor pode defini-lo como public-read-write
e conceder acesso anônimo completo ao bucket. References
