Anyone can walk up and ask for their order to get the number, and voila – access to the safe! An attacker could easily gain access to sensitive device settings, potentially leading to unauthorized control over the energy management system. This vulnerability may not be actively exploited, but leaving the door wide open can lead to absolutely devastating consequences down the road.
