Descriptions

Spinnaker is an open source, multi-cloud continuous delivery platform. Spinnaker has improper permissions allowing pipeline creation & execution. This lets an arbitrary user with access to the gate endpoint to create a pipeline and execute it without authentication. If users haven't setup Role-based access control (RBAC) with-in spinnaker, this enables remote execution and access to deploy almost any resources on any account. Patches are available on the latest releases of the supported branches and users are advised to upgrade as soon as possible. Users unable to upgrade should enable RBAC on ALL accounts and applications. This mitigates the ability of a pipeline to affect any accounts. Block application access unless permission are enabled. Users should make sure ALL application creation is restricted via appropriate wildcards.

Spinnaker es una plataforma de entrega continua multi-nube de código abierto. Spinnaker presenta permisos inapropiados que permiten la creación y ejecución de canalizaciones. Esto permite que un usuario arbitrario con acceso al endpoint de la puerta cree una canalización y la ejecute sin autenticación. Si los usuarios no han configurado el control de acceso basado en roles (RBAC) en Spinnaker, esto permite la ejecución remota y el acceso para desplegar casi cualquier recurso en cualquier cuenta. Los parches están disponibles en las últimas versiones de las ramas soportadas y se recomienda a usuarios que actualicen lo antes posible. Los usuarios que no puedan actualizar deberían habilitar RBAC en TODAS las cuentas y aplicaciones. Esto mitiga la capacidad de una tubería para afectar a cualquier cuenta. Bloquee el acceso a las aplicaciones a menos que los permisos estén habilitados. Los usuarios deben asegurarse de que TODA la creación de aplicaciones está restringida por medio de los comodines apropiados
