Vulnerabilidad · Publicado 08/09/2026
Se encontró una flaw en hawtio-operator que permite la lectura no autorizada de la clave privada de firma de la autoridad certificadora (CA) de servicios de OpenShift desde el namespace openshift-service-ca. Un atacante con permisos de creación de recursos Hawtio en cualquier namespace puede falsificar certificados de cliente con CN arbitrario, escalando privilegios en clústeres OpenShift. Esta vulnerabilidad afecta directamente a empresas en LATAM que ejecutan plataformas de contenedores en OpenShift.
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.
