Executive brief

The Ebyte NE2-D11 is a network gateway device used in industrial and energy infrastructure to manage critical communications and configurations. A low-privileged authenticated user can bypass authorization controls to access administrative functions, modify security settings, and compromise the integrity and availability of the device and the networks it protects.

Technical details
