Access Control: ACL Manipulation

Java/JSP

Abstract

应用程序允许攻击者篡改 AWS S3 存储桶或对象的访问控制策略 (ACP)。

Explanation

应用程序允许攻击者控制授予给 AWS S3 存储桶或对象的权限。这样，攻击者就可以设置低安全性策略，以便他们可以读取内容或写入任意文件。

示例 1：以下代码将使用用户指定的访问控制策略来创建新存储桶。



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

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

即使应用程序会从有限的集合中选择 acl 参数，攻击者也可以将其设置为 public-read-write 并授予对存储桶的完全匿名访问权限。
