An issue was discovered in Mercedes Benz NTG (New Telematics Generation) 6 through 2021. A possible stack buffer overflow in the Service Broker service affects NTG 6 head units. To perform this attack, physical access to Ethernet pins of the head unit base board is needed. With a static IP address, an attacker can connect via the internal network to the Service Broker service. With prepared HTTP requests, an attacker can cause the Service-Broker service to fail.
