CVE-2026-77059

The boneIO Black web interface lacks proper clickjacking protections. A remote attacker can embed the control panel in an iframe on a malicious page and trick an authenticated user on the internal network into clicking buttons that activate relays, open gates, or control blinds. Due to CVE-2026-77053 (authentication disabled by default), any user on the same internal network can trigger attacker-controlled actions by visiting the malicious website.

boneIO Black excludes several API endpoints from authentication. An unauthenticated remote attacker on the local network can retrieve system logs, firmware version, serial number, MQTT username, configuration file listings, and API documentation. This data aids reconnaissance and enables targeted attacks against the device.

boneIO black_debian_images stores the Mosquitto MQTT broker password file at /etc/mosquitto/passwd with world-readable permissions. Any local user can read the password hashes for all MQTT accounts and perform offline dictionary attacks.

boneIO Black is vulnerable to Cross-Site Request Forgery (CSRF) on all state-changing API endpoints because it lacks CSRF tokens and does not validate Origin or Referer headers. A remote attacker can craft a malicious webpage that, when visited by a user on the internal network, sends cross-origin requests to the device, allowing the attacker to reboot the controller, toggle relay circuits, control gates and blinds, or shut down the device. Due to CVE-2026-77053 (authentication disabled by default), any user on the same internal network can trigger attacker-controlled actions.

boneIO Black does not limit authentication attempts on its web interface (POST /api/login) or SSH service, and does not enforce password complexity. An unauthenticated remote attacker can make unlimited brute-force login attempts, potentially compromising user accounts and gaining unauthorized access to the device.

The boneIO black_debian_images ships with a Mosquitto MQTT broker that uses the same default credentials on all devices. These credentials are publicly documented on GitHub, and there is no indication in the instructions to change them. A remote attacker can use them to gain full read and write access to the broker, allowing control of connected relays, blinds, and gates, and injection of fake entities into a linked Home Assistant installation. This issue was fixed in version 1.6.0.

boneIO Black stores passwords, including the MQTT broker and web panel passwords, in cleartext. The GET /api/config endpoint returns the full configuration with sub-service passwords exposed, and any authenticated user can retrieve the administrative passwords in cleartext. Critically, due to CVE-2026-77053 (authentication disabled by default), an unauthenticated attacker on the same local network can retrieve all passwords.

boneIO Black firmware ships with authentication disabled by default. Its management web API listens on all network interfaces and exposes all endpoints without requiring credentials. An unauthenticated remote attacker can fully control the device, causing denial of service, modifying configuration, and operating connected physical circuits. This issue was fixed in version 1.6.0.

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.

The boneIO black_debian_images gives the boneio service account excessive privileges, including full passwordless sudo access and membership in the docker group. A local attacker who compromises the boneio user can use these privileges to escalate to root. This issue was fixed in version 1.6.0.
