Summary
JumpServer is an open source bastion host and an operation and maintenance security audit system. Prior to 4.8.0 and 3.10.18, an attacker with a low-privileged account can access the Kubernetes session feature and manipulate the kubeconfig file to redirect API requests to an external server controlled by the attacker. This allows the attacker to intercept and capture the Kubernetes cluster token. This can potentially allow unauthorized access to the cluster and compromise its security. This vulnerability is fixed in 4.8.0 and 3.10.18.

En versiones anteriores a la 4.8.0 y la 3.10.18, un atacante con una cuenta con privilegios bajos podía acceder a la función de sesión de Kubernetes y manipular el archivo kubeconfig para redirigir las solicitudes de la API a un servidor externo controlado por el atacante. Esto le permite interceptar y capturar el token del clúster de Kubernetes. Esto podría permitir el acceso no autorizado al clúster y comprometer su seguridad.
