Descriptions
openshift-ansible before versions 3.9.23, 3.7.46 deploys a misconfigured etcd file that causes the SSL client certificate authentication to be disabled. Quotations around the values of ETCD_CLIENT_CERT_AUTH and ETCD_PEER_CLIENT_CERT_AUTH in etcd.conf result in etcd being configured to allow remote users to connect without any authentication if they can access the etcd server bound to the network on the master nodes. An attacker could use this flaw to read and modify all the data about the Openshift cluster in the etcd datastore, potentially adding another compute node, or bringing down the entire cluster.
openshift-ansible en versiones anteriores a la 3.9.23 y 3.7.46 implementa un archivo etcd mal configurado que provoca que la autenticación del certificado de cliente SSL se deshabilite. Las comillas en los valores de ETCD_CLIENT_CERT_AUTH y ETCD_PEER_CLIENT_CERT_AUTH en etcd.conf resultan en que etcd se configura para permitir que usuarios remotos se conecten sin autenticación si pueden acceder al servidor etcd enlazado a la red en los nodos maestros. Un atacante puede emplear este error para leer y modificar todos los datos sobre el clúster Openshift en el almacén de datos etcd, añadiendo potencialmente otro nodo de ordenador o haciendo que caiga todo el clúster.
