Description

Amazon S3 (Simple Storage Service) is a service that provides object storage from anywhere in the world through the AWS service interface. The object are stored in containers called buckets. We have detected that the S3 Bucket {AwsS3Bucket} contains a policy that allows cross account access to AWS accounts which are not in your organization. The AWS accounts are: [{AwsS3Bucket.UnknownCrossAccountFindings}]. Unauthorized access to a bucket can lead to abuse of the S3 service such as reading, deleting and altering the data stored in the bucket.
