Descriptions

The vantage6 technology enables to manage and deploy privacy enhancing technologies like Federated Learning (FL) and Multi-Party Computation (MPC). Nodes and servers get a ssh config by default that permits root login with password authentication. In a proper deployment, the SSH service is not exposed so there is no risk, but not all deployments are ideal. The default should therefore be less permissive. The vulnerability can be mitigated by removing the ssh part from the docker file and rebuilding the docker image. Version 4.2.0 patches the vulnerability.

La tecnología vantage6 permite gestionar e implementar tecnologías que mejoran la privacidad, como el Federated Learning (FL) y la Multi-Party Computation (MPC). Los nodos y servidores obtienen una configuración ssh de forma predeterminada que permite el inicio de sesión root con autenticación de contraseña. En una implementación adecuada, el servicio SSH no queda expuesto por lo que no hay riesgo, pero no todas las implementaciones son ideales. Por lo tanto, el valor predeterminado debería ser menos permisivo. La vulnerabilidad se puede mitigar eliminando la parte ssh del archivo docker y reconstruyendo la imagen de la ventana acoplable. La versión 4.2.0 parchea la vulnerabilidad.
