CVSS: 8.1EPSS: 0%CPEs: 8EXPL: 0CVE-2019-11247 – Kubernetes kube-apiserver allows access to custom resources via wrong scope
https://notcve.org/view.php?id=CVE-2019-11247
The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges). Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.7, 1.8, 1.9, 1.10, 1.11, 1.12. El kube-apiserver de Kubernetes permite por error el acceso a un recurso personalizado de ámbito de clúster si la solicitud se realiza como si el recurso estuviera con espacio de nombres. Las autorizaciones para el recurso al que se tiene acceso de esta manera se aplican mediante roles y enlaces de roles dentro del espacio de nombres, lo que significa que un usuario con acceso solo a un recurso en un espacio de nombres podría crear, ver actualizar o eliminar el recurso de ámbito de clúster (según sus privilegios de rol de espacio de nombres). • https://access.redhat.com/errata/RHBA-2019:2816 https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHSA-2019:2690 https://access.redhat.com/errata/RHSA-2019:2769 https://github.com/kubernetes/kubernetes/issues/80983 https://groups.google.com/d/msg/kubernetes-security-announce/vUtEcSEY6SM/v2ZZxsmtFQAJ https://security.netapp.com/advisory/ntap-20190919-0003 https://access.redhat.com/security/cve/CVE-2019-11247 https://bugzilla.redhat.com/show_bug.cgi?id=1 • CWE-20: Improper Input Validation CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
CVSS: 7.8EPSS: 79%CPEs: 55EXPL: 0CVE-2019-9514 – Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9514
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de reinicio, lo que puede conducir a una denegación de servicio. El atacante abre una serie de secuencias y envía una solicitud no válida sobre cada secuencia que debería solicitar una secuencia de tramas RST_STREAM del par. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

A reflected XSS vulnerability exists in authorization flow of OpenShift Container Platform versions: openshift-online-3, openshift-enterprise-3.4 through 3.7 and openshift-enterprise-3.9 through 3.11. An attacker could use this flaw to steal authorization data by getting them to click on a malicious link.

OpenShift Container Platform before version 4.1.3 writes OAuth tokens in plaintext to the audit logs for the Kubernetes API server and OpenShift API server. A user with sufficient privileges could recover OAuth tokens from these audit logs and use them to access other resources. OpenShift Container Platform anterior a versión 4.1.3, escribe tokens OAuth en texto plano en los registros de auditoría para el servidor de la API Kubernetes y el servidor de la API OpenShift. Un usuario con privilegios suficientes podría recuperar tokens OAuth de estos registros de auditoría y usarlos para acceder a otros recursos. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10165 https://github.com/openshift/cluster-kube-apiserver-operator/pull/499 https://github.com/openshift/cluster-openshift-apiserver-operator/pull/205 https://access.redhat.com/security/cve/CVE-2019-10165 https://bugzilla.redhat.com/show_bug.cgi?id=1719092 • CWE-532: Insertion of Sensitive Information into Log File •
