Kingdom: Security Features

Software security is not security software. Here we're concerned with topics like authentication, access control, confidentiality, cryptography, and privilege management.

Access Control: ACL Manipulation

Abstract
The application allows an attacker to manipulate the Access Control Policy (ACP) on an AWS S3 bucket or object.
Explanation
The application allows an attacker to control the permissions granted to an AWS S3 bucket or object. This allows the attacker to set a weak policy that can enable them to read the content or write arbitrary files.

Example 1: The following code creates a new bucket using an Access Control Policy specified by the user.



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

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



Even if the application expects the acl parameter to be selected from a limited set, an attacker can set it to public-read-write and grant full anonymous access to the bucket.
