Security audit

Secucheck

Security checks for vulnerabilities and agentic risk

Overview

This security-audit skill has a coherent purpose, but it automatically exposes the OpenClaw workspace over the local network and leaves a background web server running.

Install only if you are comfortable with a security-audit skill that runs shell checks and generates reports. Do not use the dashboard feature on shared, office, VPN, or untrusted networks unless it is changed to bind to localhost, serve only the report file, and stop automatically. The publisher should also remove unused gateway and cron capabilities, declare write behavior accurately, make public-IP checks opt-in, and HTML-escape report data.

Unauthenticated LAN Exposure of the OpenClaw Workspace

/tmp/secucheck-server.log 2>&1 & SERVER_PID=$! ``` The Skill instructions automatically invoke this server and explicitly recommend the LAN address: ```markdown ### Step 4: Auto-Open Dashboard After text report, automatically generate and serve dashboard: bash ~/.openclaw/skills/secucheck/scripts/serve_dashboard.sh The script returns JSON with `url` (LAN IP) and `local_url` (localhost). **Use the `url` field** (not localhost) when telling the user — they may access from another device. ``` ### Technical Analysis `python3 -m http.server` serves the current directory recursively. Because the script changes its working directory to `~/.openclaw/workspace`, the server exposes the entire OpenClaw workspace rather than only `secucheck-report.html`. Binding to `0.0.0.0` makes the service reachable through every available network interface. The server implements no authentication or authorization. Consequently, any host that can reach port 8766 can request other workspace files directly. The workspace scan itself identifies files such as `AGENTS.md`, `SOUL.md`, `USER.md`, `IDENTITY.md`, `TOOLS.md`, `MEMORY.md`, and `HEARTBEAT.md`. These files may contain private user information, persistent agent context, operational instructions, project data, or security-sensitive configuration. ### Attack Path 1. A user requests a security audit. 2. The Skill automatically invokes `serve_dashboard.sh`. 3. The script changes directory to `~/.openclaw/workspace`. 4.

Automatic Persistent Background Server and Unsafe Process Termination

No timeout, shutdown routine, or lifecycle association with the audit is implemented. It can therefore remain active after the audit and the initiating session have ended. Before launching the server, the script executes: ```bash pkill -f "http.server $PORT" ``` The `-f` option matches against complete process command lines. This does not establish that the matching process belongs to secucheck. An unrelated Python HTTP server using the same port and command-line pattern can be terminated. This behavior exceeds the expectations created by the Skill's “read-only” description. The implementation writes a report, kills processes, writes a log under `/tmp`, and starts a detached network service. ### Attack Path 1. A user or automated trigger starts an audit. 2. Dashboard generation invokes `serve_dashboard.sh` without a separate approval step. 3. The script uses broad command-line matching to terminate every process matching `http.server `. 4. An unrelated service with that pattern may be terminated. 5. The script launches a replacement server through `nohup`. 6. The audit finish ...[truncated 808 chars]

Update the Skill documentation and metadata to accurately disclose report writes, process creation, and network-listener behavior. 7. Prefer generating a static report and returning its local file path without creating a server. ]]>

Treat all built-in audit output and configuration-derived data as untrusted, even when it originates locally. 5. Add a restrictive Content Security Policy, for example: ```html ``` 6. Avoid inline event handlers in templates so a strong `script-src` policy can be applied. 7. Add regression tests using values that contain quotes, HTML elements, event handlers, ampersands, newlines, and backslashes. 8. Serve the report from a directory that contains no other sensitive files. ]]>

    Automatic Third-Party Public-IP Requests Disclose Audit Host Metadata

    /dev/null || curl -s --max-time 5 https://api.ipify.org 2>/dev/null || echo "") if [ -z "$external_ip" ]; then external_ip="unknown" failed_checks+=("external_ip") fi ``` ### Technical Analysis Every runtime audit attempts to contact `ifconfig.me`, falling back to `api.ipify.org`. The request has a legitimate functional purpose: comparing the public IP with local addresses to estimate whether the host is behind NAT. However, the network communication occurs automatically and is not clearly disclosed by the Skill's “read-only” description. Although the request body does not explicitly upload local files or credentials, the external provider receives the source public IP, request time, TLS and transport metadata, and potentially standard HTTP client characteristics. This behavior may be inappropriate in privacy-sensitive, air-gapped, or regulated environments where a local security audit is expected not to contact external services. ### Attack Path 1. A user requests a local OpenClaw security audit. 2. `full_audit.sh` invokes `runtime_check.sh`. 3. `runtime_check.sh` automatically sends an HTTPS request to `ifconfig.me`. 4. If the first request fails, it sends another request to `api.ipify.org`. 5. The third-party service records or processes the audit host's network metadata. 6. The returned address is placed into the audit output and generated dashboard. ### Impact Assessment The disclosed information is limited primarily to network metadata, but it can reveal: - The audit host's public IP address - The approximate time an audit was performed - The use of a command-line HTTP client - Organizational or geographic information inferable from the source networ ...[truncated 129 chars]
