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.

Impact

The vulnerability in the Hawtio operator allows an attacker who has edit access in any namespace to generate Service‑CA‑signed client certificates with an arbitrary Subject Common Name (CN). By supplying a custom Hawtio resource, the operator uses the OpenShift Service‑CA private signing key to mint a certificate that can impersonate any in‑cluster service identity. This can be used to subvert clients that trust the Service‑CA for authentication, such as Jolokia agents and other Service‑CA‑trusting components. The flaw therefore provides a path to covertly impersonate privileged services and potentially conduct further attacks on the cluster.

Affected Systems

Red Hat builds of Apache Camel – HawtIO 4 deployed in OpenShift environments. No specific version numbers are listed, so all instances of this operator are potentially affected.

Risk and Exploitability

The CVSS score of 9.9 marks this flaw as critical. The EPSS score is not available, so the likelihood of widespread exploitation is unknown, but the flaw is listed in no KEV catalog, implying no publicly known exploits yet. The attack vector likely requires an edit‑level user to create or modify a Hawtio custom resource; this inference is based on the description and is not directly stated in the input.

Remediation

Vendor Workaround

Do not set spec.routeHostName to values outside the operator's own namespace service names. Restrict which users can create or modify Hawtio custom resources via RBAC. Audit existing Hawtio CR instances for unexpected routeHostName values and rotate any TLS certificates that may have been issued with incorrect Common Names.


OpenCVE Recommended Actions

  • Apply the vendor‑supplied patch or upgrade to a fixed version of the Hawtio operator.
  • Limit RBAC so that only trusted users can create or modify Hawtio custom resources, and remove the aggregation of Hawtio CR permissions into the namespace edit and admin roles.
  • Do not set spec.routeHostName to values outside the operator’s own namespace service names; audit existing Hawtio CR instances for unexpected routeHostName values and rotate any TLS certificates that may have been issued with incorrect Common Names.
