Summary
FrodoBots EarthRover Mini+ firmware contains a flaw in its MQTT message handling that lets an attacker run arbitrary shell commands as root on the device. The attack can be carried out remotely, and the only gate is shared IoT credentials rather than per-device authentication, so one set of credentials could expose the whole fleet.

Read the original description
FrodoBots EarthRover Mini+ firmware (version 6.2.4_6.2.5_0.614.0) is vulnerable to unauthenticated, remote code execution via MQTT. A firmware method accepts arbitrary shell commands delivered via Amazon Web Services Internet of Things Message Queuing Telemetry Transport (AWS IoT MQTT) messages and executes them as root. Access is gated only by shared Internet of Things (IoT) credentials, with no per‑device authentication, enabling remote code execution as root across the fleet.
