Description
boneIO Black exposes a Node-RED instance without authentication at the /nodered/ path through a Caddy reverse proxy. The Node-RED Admin API allows deploying flows that can execute arbitrary system commands. An unauthenticated attacker on the local network can deploy a malicious flow to achieve remote code execution and gain full control over the home automation system. This issue was fixed in version 1.6.0.
Attack Chain
Attacker identifies vulnerable service instances using Shodan, Censys, or active scanning
