| 제목 | unitedbyai droidclaw <= v0.5.3 Improper Restriction of Excessive Authentication Attempts (CWE-307) |
|---|
| 설명 | # Technical Details
An Unauthenticated Authentication Bypass via Rate Limiter Evasion and IP Spoofing exists in the `/pairing/claim` endpoint in `server/src/routes/pairing.ts` of droidclaw.
The application fails to properly rate limit authentication attempts against 6-digit pairing codes because it trusts the highly spoofable `X-Forwarded-For` and `X-Real-IP` HTTP headers to track rate-limiting attempts. The `isRateLimited()` function caches request attempts using this spoofable IP address as the map key.
# Vulnerable Code
File: server/src/routes/pairing.ts
Method: /pairing/claim endpoint
Why: The logic extracts the user's IP directly from the untrusted `x-forwarded-for` and `x-real-ip` headers, and uses it as a key for the rate limiter.
# Reproduction
1. Set up a running instance of the Droidclaw server.
2. Execute the brute-force PoC exploit script against the target endpoint.
3. Observe that the rate limit is entirely bypassed due to the randomized `x-forwarded-for` header, and the pairing code is successfully guessed.
# Impact
- An unauthenticated attacker can steal any active user's API key.
- Full control over the victim's Android device by connecting to the WebSocket API. |
