CVSS: 6.5EPSS: 0%CPEs: 9EXPL: 0CVE-2019-11249 – kubectl cp allows symlink directory traversal
https://notcve.org/view.php?id=CVE-2019-11249
The kubectl cp command allows copying files between containers and the user machine. To copy files from a container, Kubernetes runs tar inside the container to create a tar archive, copies it over the network, and kubectl unpacks it on the user’s machine. If the tar binary in the container is malicious, it could run any code and output unexpected, malicious results. An attacker could use this to write files to any path on the user’s machine when kubectl cp is called, limited only by the system permissions of the local user. Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.1, 1.2, 1.4, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11, 1.12. • https://access.redhat.com/errata/RHBA-2019:2794 https://access.redhat.com/errata/RHBA-2019:2816 https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHSA-2019:3239 https://access.redhat.com/errata/RHSA-2019:3811 https://github.com/kubernetes/kubernetes/issues/80984 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-2019-11249& • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-61: UNIX Symbolic Link (Symlink) Following •

Jenkins 2.191 and earlier, LTS 2.176.2 and earlier allowed users to obtain CSRF tokens without an associated web session ID, resulting in CSRF tokens that did not expire and could be used to bypass CSRF protection for the anonymous user. Jenkins 2.191 y anteriores, LTS 2.176.2 y anteriores permitieron a los usuarios obtener tokens CSRF sin un ID de sesión web asociado, lo que resultó en tokens CSRF que no caducaron y podrían usarse para omitir la protección CSRF para el usuario anónimo. A flaw was found in Jenkins. Users are allowed to obtain CSRF tokens without an associated web session ID, resulting in CSRF tokens that did not expire and could be used to bypass CSRF protection for the anonymous user. The highest threat from this vulnerability is to data confidentiality and integrity. • http://www.openwall.com/lists/oss-security/2019/08/28/4 https://access.redhat.com/errata/RHSA-2019:2789 https://access.redhat.com/errata/RHSA-2019:3144 https://jenkins.io/security/advisory/2019-08-28/#SECURITY-1491 https://www.oracle.com/security-alerts/cpuapr2022.html https://access.redhat.com/security/cve/CVE-2019-10384 https://bugzilla.redhat.com/show_bug.cgi?id=1747297 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-352: Cross-Site Request Forgery (CSRF) •

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: 4%CPEs: 44EXPL: 0CVE-2019-9515 – Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9515
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de configuraciones, lo que puede conducir a una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://seclists.org/fulldisclosure/2019/Aug/16 https://access.redhat.com/errata/RHSA-2019:2766 https://access.redhat.com/errata/RHSA-2019:2796 https://access.redhat.com/errata/RHSA-2019:2861 https://access.redhat.com/errata/RHSA-2019:2925 https://access.redhat.com/errata/RHSA-2019:2939 https://access.redhat.com/errata/RHSA-2019:2955 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
