https://notcve.org/view.php?id=CVE-2021-32001
K3s in SUSE Rancher allows any user with direct access to the datastore, or a copy of a datastore backup, to extract the cluster's confidential keying material (cluster certificate authority private keys, secrets encryption configuration passphrase, etc.) and decrypt it, without having to know the token value. This issue affects: SUSE Rancher K3s version v1.19.12+k3s1, v1.20.8+k3s1, v1.21.2+k3s1 and prior versions; RKE2 version v1.19.12+rke2r1, v1.20.8+rke2r1, v1.21.2+rke2r1 and prior versions. K3s en SUSE Rancher permite a cualquier usuario con acceso directo al almacén de datos, o a una copia de seguridad del almacén de datos, extraer el material de clave confidencial del clúster (claves privadas de la autoridad de certificación del clúster, frase de contraseña de configuración de cifrado de secretos, etc.) y descifrarlo, sin tener que conocer el valor del token. Este problema afecta a: SUSE Rancher K3s versión v1.19.12+k3s1, v1.20.8+k3s1, v1.21.2+k3s1 y versiones anteriores; RKE2 versión v1.19.12+rke2r1, v1.20.8+rke2r1, v1.21.2+rke2r1 y versiones anteriores • https://bugzilla.suse.com/show_bug.cgi?id=1188453 • CWE-311: Missing Encryption of Sensitive Data •

Rancher 2 through 2.2.4 is vulnerable to a Cross-Site Websocket Hijacking attack that allows an exploiter to gain access to clusters managed by Rancher. The attack requires a victim to be logged into a Rancher server, and then to access a third-party site hosted by the exploiter. Once that is accomplished, the exploiter is able to execute commands against the cluster's Kubernetes API with the permissions and identity of the victim. Rancher versiones 2 hasta 2.2.4, es vulnerable a un ataque de tipo Cross-Site Websocket Hijacking, que permite a un explotador conseguir acceso a los clústeres administrados por Rancher. El ataque requiere que una víctima este registrada dentro de un servidor de Rancher y luego acceda a un sitio de terceros alojado por el explotador. • https://forums.rancher.com/c/announcements https://forums.rancher.com/t/rancher-release-v2-2-5-addresses-rancher-cve-2019-13209/14801 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

An issue was discovered that affects the following versions of Rancher: v2.0.0 through v2.0.13, v2.1.0 through v2.1.8, and v2.2.0 through 2.2.1. When Rancher starts for the first time, it creates a default admin user with a well-known password. After initial setup, the Rancher administrator may choose to delete this default admin user. If Rancher is restarted, the default admin user will be recreated with the well-known default password. An attacker could exploit this by logging in with the default admin credentials. • https://forums.rancher.com/c/announcements https://rancher.com/docs/rancher/v2.x/en/security • CWE-287: Improper Authentication •
