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.

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 •

CVE-2017-7481 – ansible: Security issue with lookup return not tainting the jinja2 environment

https://notcve.org/view.php?id=CVE-2017-7481

Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated. Ansible en versiones anteriores a la 2.3.1.0 y 2.4.0.0 no marca correctamente los resultados del plugin lookup como no seguros. Si un atacante pudiese controlar los resultados de las llamadas lookup(), podrían inyectar cadenas Unicode para que sean analizadas por el sistema de plantillas jinja2, resultando en una ejecución de código. • http://www.securityfocus.com/bid/98492 https://access.redhat.com/errata/RHSA-2017:1244 https://access.redhat.com/errata/RHSA-2017:1334 https://access.redhat.com/errata/RHSA-2017:1476 https://access.redhat.com/errata/RHSA-2017:1499 https://access.redhat.com/errata/RHSA-2017:1599 https://access.redhat.com/errata/RHSA-2017:2524 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-7481 https://github.com/ansible/ansible/commit/ed56f51f185a1ffd7ea57130d260098686fcc7c2 https://lists.deb • CWE-20: Improper Input Validation •

CVE-2016-8651 – 3: Pulling of any image is possible with it manifest

https://notcve.org/view.php?id=CVE-2016-8651

An input validation flaw was found in the way OpenShift 3 handles requests for images. A user, with a copy of the manifest associated with an image, can pull an image even if they do not have access to the image normally, resulting in the disclosure of any information contained within the image. S ha encontrado un error de validación de entradas en la forma en la que OpenShift 3 gestiona peticiones para imágenes. Un usuario, con una copia del manifiesto asociado con una imagen, puede extraer una imagen incluso aunque normalmente no cuente con acceso a la misma. Esto resulta en la divulgación de información contenida en la imagen. • http://www.securityfocus.com/bid/94935 https://access.redhat.com/errata/RHSA-2016:2915 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-8651 https://access.redhat.com/security/cve/CVE-2016-8651 https://bugzilla.redhat.com/show_bug.cgi?id=1397987 • CWE-20: Improper Input Validation •
