- Unauthenticated Exposure of Household State on All Network Interfaces<![CDATA[ ## Vulnerability Details **File Location**: `SKILL.md:40-44` **Additional Location**: `README.md:96-101` **Vulnerability Type**: Unauthenticated network exposure and insufficient interface binding **Risk Level**: Medium ### Vulnerable Code ```bash cd {baseDir}/VisuoSpatialSketchpad && python3 -m http.server 8000 ``` The corresponding setup instructions in `README.md` use the same server configuration: ```bash cd VisuoSpatialSketchpad python -m http.server 8000 ``` ### Technical Analysis Python's `http.server` binds to all available network interfaces by default when no `--bind` argument is supplied. Consequently, this command does not restrict the dashboard to `localhost`, even though the project describes the service as locally hosted. The server exposes the entire `VisuoSpatialSketchpad` directory without authentication or authorization. After setup, that directory includes `earl_mind.json`, which may contain: - Precise latitude, longitude, and timezone - Household name - Room occupancy and security status - Household reminders and activities - Behavioral observations and long-term patterns - Mood, notes, and other private household information Any host able to reach TCP port 8000 can request these files directly. The issue is particularly significant on shared, untrusted, or poorly segmented local networks. ### Attack Path 1. A user follows the documented command and starts `python3 -m http.server 8000`. 2. The server listens on all available interfaces rather than only loopback. 3. An attacker on a reachable network scans the host or otherwise discovers port 8000. 4. The attacker requests: ```text http://HOST_IP:8000/earl_mind.json ``` 5. The server returns the household state without requesting authentication. 6. The attacker can repeatedly retrieve the file to monitor changes in occupancy, reminders, and other household activity. ### Impact Assessment An attacker does not gain operating-system command execution from this ...[truncated 575 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Bind the server explicitly to the loopback interface: ```bash python3 -m http.server 8000 --bind 127.0.0.1 ``` 2. Update every operating-system-specific instruction and example to use the restricted binding. 3. Do not serve private state from the same unauthenticated document root as public static assets. Place the dashboard assets in a dedicated public directory. 4. If remote display access is required, replace `http.server` with an application server that provides: - Authentication and authorization - TLS - Explicit route allowlisting - Secure response headers - Access logging and rate limiting 5. Configure host firewall rules to reject inbound connections to port 8000 from non-loopback interfaces. 6. Minimize the data returned to the browser. Avoid exposing precise coordinates, room status, or long-term household observations unless those fields are required by the display. ]]>
