SCA: security update for @aws-cdk/aws-eks, aws-cdk-lib (GHSA-rx28-r23p-2qc3)

high Tenable Self-Hosted Container Security Plugin ID 418980

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - AWS Cloud Development Kit (AWS CDK) is an open-source software development framework to define cloud
 infrastructure in code and provision it through AWS CloudFormation. In the packages `aws-cdk-lib` 2.0.0
 until 2.80.0 and `@aws-cdk/aws-eks` 1.57.0 until 1.202.0, `eks.Cluster` and `eks.FargateCluster`
 constructs create two roles, `CreationRole` and `default MastersRole`, that have an overly permissive
 trust policy. The first, referred to as the `CreationRole`, is used by lambda handlers to create the
 cluster and deploy Kubernetes resources (e.g `KubernetesManifest`, `HelmChart`, ...) onto it. Users with
 CDK version higher or equal to 1.62.0 (including v2 users) may be affected. The second, referred to as the
 `default MastersRole`, is provisioned only if the `mastersRole` property isn't provided and has
 permissions to execute `kubectl` commands on the cluster. Users with CDK version higher or equal to 1.57.0
 (including v2 users) may be affected. The issue has been fixed in `@aws-cdk/aws-eks` v1.202.0 and `aws-
 cdk-lib` v2.80.0. These versions no longer use the account root principal. Instead, they restrict the
 trust policy to the specific roles of lambda handlers that need it. There is no workaround available for
 CreationRole. To avoid creating the `default MastersRole`, use the `mastersRole` property to explicitly
 provide a role. (CVE-2023-35165)
