CVE-2018-1085 – openshift-ansible: Incorrectly quoted values in etcd.conf causes disabling of SSL client certificate authentication
https://notcve.org/view.php?id=CVE-2018-1085
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. • https://access.redhat.com/errata/RHSA-2018:2013 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1085 https://access.redhat.com/security/cve/CVE-2018-1085 https://bugzilla.redhat.com/show_bug.cgi?id=1557822 • CWE-287: Improper Authentication CWE-592: DEPRECATED: Authentication Bypass Issues •
CVE-2018-1070 – Routing: Malicous Service configuration can bring down routing for an entire shard.
https://notcve.org/view.php?id=CVE-2018-1070
routing before version 3.10 is vulnerable to an improper input validation of the Openshift Routing configuration which can cause an entire shard to be brought down. A malicious user can use this vulnerability to cause a Denial of Service attack for other users of the router shard. routing en versiones anteriores a la 3.10 es vulnerable a una validación de entradas incorrecta de la configuración de Openshift Routing que puede permitir que una partición entera se caiga. Un usuario malicioso puede emplear esta vulnerabilidad para provocar un ataque de denegación de servicio (DoS) para otros usuarios de la partición del router. Improper input validation of the Openshift Routing configuration can cause an entire shard to be brought down. A malicious user can use this vulnerability to cause a Denial of Service attack for other users of the router shard. • https://access.redhat.com/errata/RHSA-2018:2013 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1070 https://access.redhat.com/security/cve/CVE-2018-1070 https://bugzilla.redhat.com/show_bug.cgi?id=1553035 • CWE-20: Improper Input Validation •
CVE-2017-12195 – 3: authentication bypass for elasticsearch with external routes
https://notcve.org/view.php?id=CVE-2017-12195
A flaw was found in all Openshift Enterprise versions using the openshift elasticsearch plugin. An attacker with knowledge of the given name used to authenticate and access Elasticsearch can later access it without the token, bypassing authentication. This attack also requires that the Elasticsearch be configured with an external route, and the data accessed is limited to the indices. Se ha encontrado un fallo en todas las versiones de Openshift Enterprise que utilizan el plugin openshift elasticsearch. Un atacante con conocimiento del nombre usado para autenticar y acceder a Elasticsearch puede acceder a él más tarde sin el token, evitando la autenticación. • https://access.redhat.com/errata/RHSA-2017:3188 https://access.redhat.com/errata/RHSA-2017:3389 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-12195 https://access.redhat.com/security/cve/CVE-2017-12195 https://bugzilla.redhat.com/show_bug.cgi?id=1501986 • CWE-287: Improper Authentication CWE-295: Improper Certificate Validation •
