The "Rich Filemanager" feature of Artica Proxy provides a web-based interface for file management capabilities. When the feature is enabled, it does not require authentication by default, and runs as the root user.

Services that are running and bound to the loopback interface on the Artica Proxy are accessible through the proxy service. In particular, the "tailon" service is running, running as the root user, is bound to the loopback interface, and is listening on TCP port 7050. Security issues associated with exposing this network service are documented at gvalkov's 'tailon' GitHub repo. Using the tailon service, the contents of any file on the Artica Proxy can be viewed.
