| タイトル | man-group dtale <=3.22.0 Improper Restriction of Excessive Authentication Attempts |
|---|
| 説明 | When authentication is enabled, D-Tale exposes a /login route that accepts username/password via an HTML form. On failure it simply re-renders the login template with an error and permits an immediate retry. The implementation contains:
-No rate limiting (no per-IP or per-account request throttling),
-No account lockout after repeated failures,
-No incremental delay / exponential backoff,
-No CAPTCHA or challenge-response,
-No attempt counter of any kind.
An attacker can therefore submit credential guesses as fast as the network and server allow. At a conservative 50–500 requests/second, a 1,000,000-entry wordlist (e.g. rockyou) is exhausted in roughly 5.6 hours down to ~36 minutes. Because credentials are stored and compared in plaintext (no hashing/salting), and the comparison uses Python's non-constant-time ==, any weak or default password is recovered quickly. The plaintext storage means the configured password is also directly disclosed by any read of the config file (~/.config/dtale.ini or DTALE_CONFIG), and the non-constant-time compare is a theoretical timing side channel (largely masked by network jitter in practice, hence listed as compounding rather than primary).
Once a valid username/password is found, the attacker logs in normally, the server sets session["logged_in"] = True / session["username"], and the requires_auth decorator grants full access to all protected routes. |
