CVE-2022-31076

Estado: ModificadaMedia (5.7)—

KubeEdge is built upon Kubernetes and extends native containerized application orchestration and device management to hosts at the Edge. In affected versions a malicious message can crash CloudCore by triggering a nil-pointer dereference in the UDS Server. Since the UDS Server only communicates with the CSI Driver on the cloud side, the attack is limited to the local host network. As such, an attacker would already need to be an authenticated user of the Cloud. Additionally it will be affected only when users turn on the unixsocket switch in the config file cloudcore.yaml.

En versiones afectadas, un mensaje malicioso puede bloquear CloudCore al desencadenar una desreferencia de puntero nil en el servidor UDS. Dado que el servidor UDS sólo es comunicado con el controlador CSI en el lado de la nube, el ataque es limitado a la red local del host. Como tal, un atacante ya necesitaría ser un usuario autenticado de la Nube. Además, sólo será afectado cuando los usuarios activen el interruptor unixsocket en el archivo de configuración cloudcore.yaml. Este error ha sido corregido en Kubeedge versiones 1.11.0, 1.10.1 y 1.9.3. Los usuarios deben actualizar a estas versiones para resolver el problema.
