- Summary
- AWS CDK EKS overly permissive trust policies
- Details
-
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-lib2.0.0 until 2.80.0 and@aws-cdk/aws-eks1.57.0 until 1.202.0,eks.Clusterandeks.FargateClusterconstructs create two roles,CreationRoleanddefault 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.gKubernetesManifest,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 themastersRoleproperty isn't provided and has permissions to executekubectlcommands 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-eksv1.202.0 andaws-cdk-libv2.80.0. 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 thedefault MastersRole, use themastersRoleproperty to explicitly provide a role. - Database specific
