소프트웨어 보안은 보안 소프트웨어가 아닙니다. 여기서는 인증, 액세스 제어, 기밀성, 암호화, 권한 관리 등의 항목에 대해 설명합니다.

Access Control: ACL Manipulation

Abstract
응용 프로그램은 공격자가 AWS S3 버킷 또는 개체의 ACP(액세스 제어 정책)를 조작할 수 있도록 허용합니다.
Explanation
응용 프로그램은 공격자가 AWS S3 버킷 또는 개체에 대해 부여된 권한을 조작할 수 있도록 허용합니다. 이를 통해 공격자는 콘텐트를 읽거나 임의의 파일을 쓸 수 있는 약한 정책을 설정할 수 있습니다.

예제 1: 다음 코드는 사용자가 지정한 액세스 제어 정책을 사용하여 새 버킷을 생성합니다.



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

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



응용 프로그램이 제한된 집합에서 acl 매개 변수를 선택한다고 해도 공격자는 이를 public-read-write로 설정하고 버킷에 대한 전체 익명 액세스 권한을 부여할 수 있습니다.
