Detailsinfo

A vulnerability was found in Amazon AWS Harmonix up to 0.4.1. It has been rated as critical. This issue affects an unknown code block. The manipulation with an unknown input leads to a privileges assignment vulnerability. Using CWE to declare the problem leads to CWE-266. A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An overly-permissive IAM trust policy in the Harmonix on AWS framework may allow IAM principals in the same AWS account to escalate privileges via role assumption. The sample code for the EKS environment provisioning role is configured to trust the account root principal, which may enable any IAM principal in the same AWS account with sts:AssumeRole permissions to assume the role with administrative privileges. We recommend customers upgrade to Harmonix on AWS v0.4.2 or later if you have deployed the framework using versions v0.3.0 through v0.4.1.
