Technical details
The web interface signs JWT access tokens using the SSL certificate instead of a secret key, and uses a default certificate that is publicly known or easily predicted. An attacker can forge valid JWT tokens to bypass authentication and gain administrative privileges. An attacker needs network access to the web interface; no user interaction or pre-existing authentication is required.
