The Blackmagic ATEM Mini Pro 2.7 exposes an undocumented Telnet service on TCP port 9993, which accepts unauthenticated plaintext commands for controlling streaming, recording, formatting storage devices, and system reboot. This interface, referred to as the ATEM Ethernet Protocol 1.0, provides complete device control without requiring credentials or encryption. An attacker on the same network (or with remote access to the exposed port) can exploit this interface to execute arbitrary streaming commands, erase disks, or shut down the device - effectively gaining full remote control.
The product does not properly control the allocation and maintenance of a limited resource.
Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
