| 제목 | github.com/Travisun/Opptrix Opptrix Server v0.4.0 Command Injection |
|---|
| 설명 | A self-hosted Opptrix server (open source, github.com/Travisun/Opptrix) exposes all API endpoints without authentication from first launch until the owner completes account setup, which is the default claimed:false state of a fresh deployment. In this setup window, POST /api/auth/setup is first-come-first-served: whoever reaches it first receives the single administrator account permanently, while the legitimate owner is locked out with HTTP 409.
The schedule API then accepts a job of kind shell_script whose argv may be ["node","-e","<arbitrary JavaScript>"]; the command blocklist only rejects shell wrappers and the exact -c / /c arguments. Running the job via POST /api/schedule/jobs/{id}/run executes that argv with the privileges of the service process, and a non-zero exit code routes the command's stdout into the run record, giving the attacker output readback (demonstrated with whoami, hostname, and reading the key-vault key file).
The APIs carry no CORS headers, but JSON POSTs against a locally running instance can be reached same-origin through DNS rebinding because the server performs no Host header validation, so a malicious web page can drive the entire chain against a victim's local deployment with no interaction beyond browsing.
Verified against v0.4.0 (current main branch, self-reported via /api/health) on Windows. Impact: permanent takeover of fresh deployments, arbitrary command execution with service privileges, and command output disclosure; the executed code reaches the data directory including the user database and key vault.
