## Overview

A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). A special maintenance mode can be activated via a physical key sequence during device boot, in which the device downloads and executes program code from a network server without verifying its authenticity or integrity. This could allow an attacker with physical access to the device to upload and execute arbitrary, unsigned code.
