Description

A flaw was found in hawtio-operator. The operator reads the OpenShift Service CA private signing key from the openshift-service-ca namespace and uses it to mint client certificates with a Subject Common Name (CN) supplied by the author of a namespaced Hawtio custom resource. Because the operator ships a ClusterRole that aggregates Hawtio CR permissions into the edit and admin roles, any user with edit access in any namespace can obtain a Service-CA-signed certificate with an arbitrary subject. This certificate can be used to impersonate any in-cluster service identity to peers that trust the Service CA for client authentication, including Jolokia agents and other Service-CA-trusting components.
