CVSS: 6.3EPSS: 0%CPEs: 1EXPL: 0CVE-2020-8563 – Secret leaks in logs for vSphere Provider kube-controller-manager
https://notcve.org/view.php?id=CVE-2020-8563
In Kubernetes clusters using VSphere as a cloud provider, with a logging level set to 4 or above, VSphere cloud credentials will be leaked in the cloud controller manager's log. This affects < v1.19.3. En los clústeres de Kubernetes que utilizan VSphere como proveedor de nube, con un nivel de registro establecido en 4 o superior, las credenciales de la nube de VSphere se filtrarán en el registro del administrador del controlador de nube. Esto afecta a versiones anteriores a v1.19.3 A flaw was found in kubernetes. Clusters running on VSphere, using VSphere as a cloud provider a with logging level set to 4 or above, VSphere cloud credentials will be leaked in the cloud controller manager's log. • https://github.com/kubernetes/kubernetes/issues/95621 https://groups.google.com/g/kubernetes-security-discuss/c/vm-HcrFUOCs/m/36utxAM5CwAJ https://security.netapp.com/advisory/ntap-20210122-0006 https://access.redhat.com/security/cve/CVE-2020-8563 https://bugzilla.redhat.com/show_bug.cgi?id=1886635 • CWE-117: Improper Output Neutralization for Logs CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-8565 – Incomplete fix for CVE-2019-11250 allows for token leak in logs when logLevel >= 9
https://notcve.org/view.php?id=CVE-2020-8565
In Kubernetes, if the logging level is set to at least 9, authorization and bearer tokens will be written to log files. This can occur both in API server logs and client tool output like kubectl. This affects <= v1.19.3, <= v1.18.10, <= v1.17.13, < v1.20.0-alpha2. En Kubernetes, si el nivel de registro se establece en al menos 9, los tokens de autorización y portador se escribirán en los archivos de registro. Esto puede ocurrir tanto en los registros del servidor API como en la salida de la herramienta cliente como kubectl. • https://github.com/kubernetes/kubernetes/issues/95623 https://groups.google.com/g/kubernetes-security-discuss/c/vm-HcrFUOCs/m/36utxAM5CwAJ https://access.redhat.com/security/cve/CVE-2020-8565 https://bugzilla.redhat.com/show_bug.cgi?id=1886638 • CWE-117: Improper Output Neutralization for Logs CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-8566 – Ceph RBD adminSecrets exposed in logs when loglevel >= 4
https://notcve.org/view.php?id=CVE-2020-8566
In Kubernetes clusters using Ceph RBD as a storage provisioner, with logging level of at least 4, Ceph RBD admin secrets can be written to logs. This occurs in kube-controller-manager's logs during provisioning of Ceph RBD persistent claims. This affects < v1.19.3, < v1.18.10, < v1.17.13. En los clústeres de Kubernetes que usan Ceph RBD como aprovisionador de almacenamiento, con un nivel de registro de al menos 4, los secretos de administración de Ceph RBD se pueden escribir en los registros. Esto ocurre en los registros de kube-controller-manager durante el aprovisionamiento de notificaciones persistentes de Ceph RBD. • https://github.com/kubernetes/kubernetes/issues/95624 https://groups.google.com/g/kubernetes-security-discuss/c/vm-HcrFUOCs/m/36utxAM5CwAJ https://security.netapp.com/advisory/ntap-20210122-0006 https://access.redhat.com/security/cve/CVE-2020-8566 https://bugzilla.redhat.com/show_bug.cgi?id=1886640 • CWE-117: Improper Output Neutralization for Logs CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-8564 – Docker config secrets leaked when file is malformed and loglevel >= 4
https://notcve.org/view.php?id=CVE-2020-8564
In Kubernetes clusters using a logging level of at least 4, processing a malformed docker config file will result in the contents of the docker config file being leaked, which can include pull secrets or other registry credentials. This affects < v1.19.3, < v1.18.10, < v1.17.13. En los clústeres de Kubernetes que usan un nivel de registro de al menos 4, el procesamiento de un archivo de configuración de docker malformado dará como resultado la filtración del contenido del archivo de configuración de docker, que puede incluir secretos de extracción u otras credenciales de registro. Esto afecta versiones anteriores a v1.19.3, versiones anteriores a v1.18.10, versiones anteriores a v1.17.13 A flaw was found in kubernetes. In Kubernetes, if the logging level is to at least 4, processing a malformed docker config file will result in the contents of the docker config file being leaked, which can include pull secrets or other registry credentials. • https://github.com/kubernetes/kubernetes/issues/95622 https://groups.google.com/g/kubernetes-security-discuss/c/vm-HcrFUOCs/m/36utxAM5CwAJ https://security.netapp.com/advisory/ntap-20210122-0006 https://access.redhat.com/security/cve/CVE-2020-8564 https://bugzilla.redhat.com/show_bug.cgi?id=1886637 • CWE-117: Improper Output Neutralization for Logs CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-8557 – Kubernetes node disk Denial of Service by writing to container /etc/hosts
https://notcve.org/view.php?id=CVE-2020-8557
The Kubernetes kubelet component in versions 1.1-1.16.12, 1.17.0-1.17.8 and 1.18.0-1.18.5 do not account for disk usage by a pod which writes to its own /etc/hosts file. The /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager when calculating ephemeral storage usage by a pod. If a pod writes a large amount of data to the /etc/hosts file, it could fill the storage space of the node and cause the node to fail. El componente kubelet de Kubenetes versiones 1.1-1.16.12, 1.17.0-1.17.8 y 1.18.0-1.18.5, no cuenta para el uso del disco por parte de un pod que escribe en su propio archivo /etc/hosts. El archivo /etc/hosts montado en un pod para kubelet no esta incluido para el administrador de desalojo de kubelet al calcular el uso de almacenamiento efímero por un pod. • https://github.com/kubernetes/kubernetes/issues/93032 https://groups.google.com/g/kubernetes-security-announce/c/cB_JUsYEKyY/m/vVSO61AhBwAJ https://security.netapp.com/advisory/ntap-20200821-0002 https://access.redhat.com/security/cve/CVE-2020-8557 https://bugzilla.redhat.com/show_bug.cgi?id=1835977 • CWE-400: Uncontrolled Resource Consumption •
