Descriptions

A Cleartext Storage of Sensitive Information vulnerability in SUSE Rancher allows authenticated Cluster Owners, Cluster Members, Project Owners, Project Members and User Base to use the Kubernetes API to retrieve plaintext version of sensitive data. This issue affects: SUSE Rancher Rancher versions prior to 2.5.16; Rancher versions prior to 2.6.7.

Una vulnerabilidad de Almacenamiento en Texto sin Cifrar de Información confidencial en SUSE Rancher permite a propietarios de clústeres, los miembros de clústeres, los propietarios de proyectos, los miembros de proyectos y la base de usuarios autenticados usar la API de Kubernetes para recuperar una versión en texto sin cifrar de datos confidenciales. Este problema afecta a: SUSE Rancher versiones anteriores a 2.5.16; Rancher versiones anteriores a 2.6.7

An issue was discovered in Rancher versions up to and including 2.5.15 and 2.6.6 where sensitive fields, like passwords, API keys and Ranchers service account token (used to provision clusters), were stored in plaintext directly on Kubernetes objects like Clusters, for example cluster.management.cattle.io. Anyone with read access to those objects in the Kubernetes API could retrieve the plaintext version of those sensitive data.
