Technical details
The /authenticate endpoint in the Node.js ZTP web service passes unsanitized username and password parameters to shell execution via child_process.exec(). An incomplete sanitizer removes regex metacharacters but allows newline injection, enabling command chaining. An unauthenticated attacker can obtain a CSRF token from an unauthenticated page load and inject newline characters to execute arbitrary commands as the versa OS user.
