Because all the docker containers share a network, users can execute specially crafted scripts to bypass the API permissions check and perform administrative actions, including reading and modifying data inside the Redis database, which can be used to read secrets and change COSMOS settings, as well as read and write to the buckets service, which holds configuration, log, and plugin files. These actions are normally only available from the Admin Console or with administrative privileges. Any user with permission to create and run scripts can connect to any service in the docker network. \n \n\"image\"\n\nFigure 1: Environment variables, including Redis credentials, found in the Script Runner container\nA Ruby script is used to expose the Redis username, password, hostname, and port.
