An issue was discovered in CommScope Ruckus Unleashed prior to 200.15.6.212.27 and 200.18.7.1.323, and in Ruckus ZoneDirector prior to 10.5.1.0.282, where a path-traversal flaw in the web interface lets the server execute attacker-supplied EJS templates outside permitted directories, allowing a remote unauthenticated attacker who can upload a template (e.g., via FTP) to escalate privileges and run arbitrary template code on the controller.
