Summary

Incorrect authorization in the issuer resolution logic in AWS Private CA Connector for Kubernetes (aws-privateca-issuer) before v1.10.1 might allow an authenticated remote user to obtain certificates, including subordinate CA certificates, signed by a cluster-scoped AWS Private CA issuer that their approval policy does not authorize. Remediation requires upgrading to v1.10.1 or the EKS add-on v1.10.1-eksbuild.1 and updating certificate requests, Certificate resources, or Ingress annotations whose issuerRef.kind is missing, incorrect, or does not match the referenced issuer.

Risk Assessment

An authenticated user could obtain unauthorized certificates, including subordinate CA certificates, undermining trust in the cluster PKI. This could enable impersonation of services or issuance of further certificates.

Recommendation

Upgrade aws-privateca-issuer to v1.10.1 or the EKS add-on to v1.10.1-eksbuild.1 and correct all issuerRef.kind references to exactly match AWSPCAIssuer or AWSPCAClusterIssuer.

Incorrect authorization in the issuer resolution logic in AWS Private CA Connector for Kubernetes (aws-privateca-issuer) before v1.10.1 might allow an authenticated remote user to obtain certificates, including subordinate CA certificates, signed by a cluster-scoped AWS Private CA issuer that their approval policy does not authorize. To remediate this issue, users should upgrade aws-privateca-issuer to version v1.10.1 or the AWS Private CA Connector for Kubernetes EKS add-on to version v1.10.1-eksbuild.1, and update any certificate requests, Certificate resources, or Ingress annotations whose issuerRef.kind is missing, incorrect, or does not match the referenced issuer, since v1.10.1 requires issuerRef.kind to be exactly AWSPCAIssuer or AWSPCAClusterIssuer and to match the issuer it references.
