CVE-2020-27833
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') •
CVE-2020-10712 – openshift/cluster-image-registry-operator: secrets disclosed in logs
https://notcve.org/view.php?id=CVE-2020-10712
A flaw was found in OpenShift Container Platform version 4.1 and later.

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 •
CVE-2019-3889 – atomic-openshift: reflected XSS in authentication flow
https://notcve.org/view.php?id=CVE-2019-3889
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. Se presenta una vulnerabilidad de tipo XSS reflejada en el flujo de autorización de OpenShift Container Platform versiones: openshift-online- versión 3, openshift-enterprise- versiones 3.4 hasta 3.7 y openshift-enterprise- versiones 3.9 hasta 3.11. Un atacante podría utilizar este defecto para robar datos de autorización logrando que hagan clic en un enlace malicioso.

CVE-2019-10165 – openshift: OAuth access tokens written in plaintext to API server audit logs
https://notcve.org/view.php?id=CVE-2019-10165
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 •
CVE-2019-10150 – atomic-openshift: OpenShift builds don't verify SSH Host Keys for the git repository
https://notcve.org/view.php?id=CVE-2019-10150
It was found that OpenShift Container Platform versions 3.6.x - 4.6.0 does not perform SSH Host Key checking when using ssh key authentication during builds. An attacker, with the ability to redirect network traffic, could use this to alter the resulting build output. Se encontró que OpenShift Container Platform versiones 3.6.x hasta 4.6.0, no realizan la comprobación de clave del host SSH cuando es usada la autenticación de la clave ssh durante las compilaciones. Un atacante, con la capacidad de redireccionar el tráfico de la red, podría usar esto para alterar la salida de compilación resultante.
