Descriptions

The elasticsearch-operator does not validate the namespace where kibana logging resource is created and due to that it is possible to replace the original openshift-logging console link (kibana console) to different one, created based on the new CR for the new kibana resource. This could lead to an arbitrary URL redirection or the openshift-logging console link damage. This flaw affects elasticsearch-operator-container versions before 4.7.

Elasticsearch-operator no comprueba el espacio de nombres donde el recurso de registro de kibana es creado y, debido a eso, es posible reemplazar el enlace de la consola de registro de openshift original (consola de kibana) por uno diferente, creado en base al nuevo CR para el nuevo recurso de kibana. Esto podría conllevar al redireccionamiento de una URL arbitraria o daños en el enlace de la consola de registro de openshift. Este fallo afecta a elasticsearch-operator-container versiones anteriores a 4.7
