Vulnerability details
The vulnerability allows a remote user to execute arbitrary operating-system commands on the Roxy-WI controller with the authority of its Ansible worker.
The vulnerability exists due to improper neutralization of template expressions in the nginx_section Ansible role when recursively rendering user-supplied Nginx configuration values. A remote user can submit a proxy-pass header value containing {{ lookup('pipe', 'id') }} through the generate=1 API path, using role-3 Nginx access to a same-group server, to execute commands on the controller.
