https://notcve.org/view.php?id=CVE-2020-27833
A Zip Slip vulnerability was found in the oc binary in openshift-clients where an arbitrary file write is achieved by using a specially crafted raw container image (.tar file) which contains symbolic links. The vulnerability is limited to the command `oc image extract`. If a symbolic link is first created pointing within the tarball, this allows further symbolic links to bypass the existing path check. This flaw allows the tarball to create links outside the tarball's parent directory, allowing for executables or configuration files to be overwritten, resulting in arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. • https://access.redhat.com/security/cve/CVE-2020-27833 https://bugzilla.redhat.com/show_bug.cgi?id=1905945 • CWE-20: Improper Input Validation CWE-59: Improper Link Resolution Before File Access ('Link Following') •

A flaw was found in OpenShift Container Platform version 4.1 and later. Sensitive information was found to be logged by the image registry operator allowing an attacker able to gain access to those logs, to read and write to the storage backing the internal image registry. The highest threat from this vulnerability is to data integrity. Se encontró un fallo en OpenShift Container Platform versiones 4.1 y posteriores. Una información confidencial fue encontrada para ser registrada por el operador del registro de imagen permitiendo a un atacante conseguir acceso a esos registros, leer y escribir en el almacenamiento que respalda el registro de imágenes interno. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10712 https://access.redhat.com/security/cve/CVE-2020-10712 https://bugzilla.redhat.com/show_bug.cgi?id=1825161 • CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 7.5EPSS: 1%CPEs: 8EXPL: 1CVE-2019-11253 – Kubernetes API Server JSON/YAML parsing vulnerable to resource exhaustion attack
https://notcve.org/view.php?id=CVE-2019-11253
Improper input validation in the Kubernetes API server in versions v1.0-1.12 and versions prior to v1.13.12, v1.14.8, v1.15.5, and v1.16.2 allows authorized users to send malicious YAML or JSON payloads, causing the API server to consume excessive CPU or memory, potentially crashing and becoming unavailable. Prior to v1.14.0, default RBAC policy authorized anonymous users to submit requests that could trigger this vulnerability. Clusters upgraded from a version prior to v1.14.0 keep the more permissive policy by default for backwards compatibility. La comprobación de entrada inapropiada en el servidor API de Kubernetes en las versiones v1.0 hasta 1.12 y versiones anteriores a v1.13.12, v1.14.8, v1.15.5 y v1.16.2, permite a los usuarios autorizados enviar cargas maliciosas de YAML o JSON, causando que el servidor API consuma demasiada CPU o memoria, fallando potencialmente y dejando de estar disponible. En versiones anteriores a v1.14.0, la política predeterminada de RBAC autorizaba a los usuarios anónimos para enviar peticiones que pudieran desencadenar esta vulnerabilidad. • https://access.redhat.com/errata/RHSA-2019:3239 https://access.redhat.com/errata/RHSA-2019:3811 https://access.redhat.com/errata/RHSA-2019:3905 https://github.com/kubernetes/kubernetes/issues/83253 https://groups.google.com/forum/#%21topic/kubernetes-security-announce/jk8polzSUxs https://security.netapp.com/advisory/ntap-20191031-0006 https://access.redhat.com/security/cve/CVE-2019-11253 https://bugzilla.redhat.com/show_bug.cgi?id=1757701 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion') •

A flaw was found during the upgrade of an existing OpenShift Container Platform 3.x cluster. Using CRI-O, the dockergc service account is assigned to the current namespace of the user performing the upgrade. This flaw can allow an unprivileged user to escalate their privileges to those allowed by the privileged Security Context Constraints.

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 •
