When rendering `Environment=` entries, attacker-controlled values are not rejected for CR/LF, and `systemdEscapeArg()` uses an incorrect whitespace-matching regex. This allows newline injection to break out of an `Environment=` line and inject standalone systemd directives (for example, `ExecStartPre=`). On service restart, the injected command is executed, resulting in local arbitrary command execution (local RCE) under the gateway service user.</p> <p>---</p> <p>### Details The issue is in `src/daemon/systemd-unit.ts`:</p> <p>- `renderEnvLines(...)` builds: - `Environment=${systemdEscapeArg(`${key}=${value}`)}` - No CR/LF validation is enforced for environment keys/values before writing unit lines. - `systemdEscapeArg(...)` uses: - `/[\\s&#34;\\\\]/` - In this regex, `\\s` is interpreted as a literal backslash + `s`, not a whitespace character class. As a result, whitespace detection/quoting behavior is incorrect. Because systemd parses unit files line-by-line, a newline inside an environment value can inject an additional directive line. Example rendered output:</p> <p>```ini Environment=INJECT=ok ExecStartPre=/bin/touch /tmp/oc15789_rce ```</p> <p>At restart time, systemd executes `ExecStartPre`, enabling command execution.</p> <p>Relevant code path/components involved in exploitation chain: - `src/daemon/systemd-unit.ts` - `src/commands/daemon-install-helpers.ts` - `src/config/env-vars.ts` - `src/config/zod-…</p> <p><strong>Affected:</strong> npm: openclaw</p> <p>### Summary A command injection vulnerability exists in OpenClaw’s Linux systemd unit generation path.
