Short explanation
An incorrect authorization vulnerability in the issuer resolution logic of AWS Private CA Connector for Kubernetes (aws-privateca-issuer) may allow authenticated remote users to obtain certificates not authorized by their approval policy.
This security flaw could enable unauthorized users to acquire sensitive certificates, including subordinate CA certificates, potentially leading to integrity breaches.
What should be done?
- Upgrade aws-privateca-issuer to version v1.10.1
- Update the AWS Private CA Connector for Kubernetes EKS add-on to version v1.10.1-eksbuild.1
- Update any certificate requests, Certificate resources, or Ingress annotations with missing or mismatched issuerRef.kind
Chain of evidence and sources
v1.10.1 öncesi sürümlerdeki hatalı yetkilendirme, kullanıcıların onay verilmeyen sertifikaları almasına yol açabilir.
Kullanıcılar aws-privateca-issuer bileşenini v1.10.1 sürümüne yükselterek bu sorunu giderebilir.
Show the technical text from the sources
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.
