security: fix auth account enumeration and add per-account lockout - #224
Crackhead-gsk wants to merge 1 commit into
Conversation
- ForgotPasswordController: return an identical generic response whether or not the submitted email exists, instead of leaking EMAIL_DOES_NOT_EXIST. - LoginController: unify "unknown user" and "wrong password" into a single INVALID_CREDENTIALS response, with a dummy password_verify() call in the unknown-user path to reduce the timing gap between the two cases. - LoginController: add per-account (not just per-IP) lockout after repeated failed logins, so credential stuffing can't be trivially bypassed by rotating source IPs. - TwoFactorController: add a tighter per-account lockout on 2FA code verification (5 attempts / 15 min), since a 6-digit TOTP code has a much smaller keyspace than a password and needs stronger brute-force protection than IP-based rate limiting alone provides. - New AccountLockoutHelper: Redis-backed, fails open (does not block login) if Redis is unavailable, consistent with the existing rate limiter's fail-open behavior. Found during an internal security review of the authentication flow.
WalkthroughAuthentication flows now use generic credential and password-reset responses. Login and two-factor verification now enforce Redis-backed per-account lockouts with retry information and failure-state cleanup. ChangesAuthentication security hardening

In `@backend/app/Controllers/User/Auth/ForgotPasswordController.php`:
- Line 148: Update the OpenAPI response documentation for the forgot-password
endpoint to match the 200 responses returned by the generic-success paths for
unknown emails and User::updateUser() failures. Revise the documented status
codes and descriptions near the endpoint definition, while leaving the
controller behavior unchanged.
- Line 148: Update ForgotPasswordController so unknown-email requests use the
same asynchronous work path or bounded timing equalization as existing-account
requests, without waiting for SMTP delivery; preserve genericSuccess for the
normalized response. Add repeated timing tests covering both account-existence
paths, and update the OpenAPI contract to match the controller’s explicit
responses instead of documenting 404 and 500 outcomes.
In `@backend/app/Controllers/User/Auth/LoginController.php`:
- Line 245: Update the OpenAPI declaration for the login route in
LoginController to document the HTTP 429 response, including the ACCOUNT_LOCKED
response payload and retry_after field, so the declared contract matches the
route behavior.
- Around line 242-247: The locked-account branch in LoginController should match
the unauthenticated invalid-credentials response: use the same status, error
code, and response shape, and remove the lockout message and retry_after
metadata. Preserve lockout enforcement internally without exposing
account-specific information before authentication succeeds.
- Line 240: Update the login flow around
AccountLockoutHelper::getLockoutRemaining, password_verify(), and
recordFailure() to reserve a lockout attempt atomically before verification,
then finalize that reservation without clearing reservations owned by other
concurrent requests. Preserve lockout enforcement and add a concurrent
regression test proving parallel requests cannot exceed the configured
verification limit.
In `@backend/app/Controllers/User/Auth/TwoFactorController.php`:
- Around line 280-281: Update the OpenAPI documentation for the
TwoFactorController post() operation to include the new 429 ACCOUNT_LOCKED
response, documenting its retry_after payload field so generated clients can
handle lockouts; leave the existing response definitions unchanged.
- Around line 275-276: Make the lockout flow around TwoFactorController’s
getLockoutRemaining, verifyKey, and recordFailure operations atomic per account
by adding an atomic attempt gate or serializing the lockout check, verification,
and failure update. Ensure concurrent requests cannot all pass the lockout check
before the failure threshold is recorded, while preserving the existing lockout
behavior.
- Line 299: Add a server-side pre-authentication gate in
TwoFactorController::post before AccountLockoutHelper::recordFailure, requiring
proof that the password authentication step for the resolved account was
completed; reject raw email/code requests that lack this prerequisite so they
cannot increment lockout failures or lock accounts.
In `@backend/app/Helpers/AccountLockoutHelper.php`:
- Line 53: Update AccountLockoutHelper methods ttl(), recordFailure(), and
clear() to catch RedisException around each Redis command: return 0 when ttl()

Update the OpenAPI response contract.
Line 148 now returns HTTP 200 for an unknown email. Line 198 returns HTTP 200 when User::updateUser() fails. However, Lines 65-67 still document a 404 for unknown emails and describe update failures as HTTP 500. Generated clients and operators will follow an outdated contract.
Proposed documentation update
- new OA\Response(response: 404, description: 'Not found - Email does not exist'),
- new OA\Response(response: 500, description: 'Internal server error - Failed to send reset email or update user'),

Equalize the unknown-email path before returning.
The existing-account path performs synchronous database, queue, event, and activity work before returning. Unknown accounts return after the lookup and optional failed event. Repeated unauthenticated requests can infer account existence from this timing difference.
Use the same asynchronous job path for both branches, or apply bounded timing equalization without waiting for SMTP delivery. Add repeated existing-account and unknown-account timing tests.
Update the OpenAPI contract. The documented 404 for unknown emails and 500 for update failures no longer match the controller’s explicit responses.

Make the lockout decision atomic.
getLockoutRemaining() runs before password_verify(), while recordFailure() runs afterward. Parallel requests can therefore perform more than 10 password verifications before Redis creates the lock.
Use an atomic Redis reservation and finalization flow. Ensure a successful request cannot clear reservations belonging to other in-flight requests. Add a concurrent regression test.

Use a generic unauthenticated response for locked accounts.

Return the same status, code, and response shape as invalid credentials until authentication succeeds. Do not expose retry metadata before account possession.

phpredis Redis::OPT_THROW_EXCEPTIONS default command failure disconnected connection RedisException official documentation
💡 Result:
In the phpredis extension, the Redis::OPT_THROW_EXCEPTIONS option is enabled by default [1][2][3]. When this option is active, phpredis is designed to throw a RedisException object specifically when it cannot reach or communicate with the Redis server (e.g., connectivity issues, service downtime, or overloaded hosts) [2][3][4]. For other types of failures—such as a key not existing or an invalid command—the library typically returns FALSE rather than throwing an exception [2][3][4]. While the extension aims to throw a RedisException during connection-related failures, there are rare edge cases where it may return FALSE instead [3][4]. You can manually toggle this behavior using the setOption method: $redis->setOption(Redis::OPT_THROW_EXCEPTIONS, true); // Ensure exceptions are enabled $redis->setOption(Redis::OPT_THROW_EXCEPTIONS, false); // Disable exceptions The RedisException class itself extends the built-in RuntimeException class [5]. Internal implementation details in the phpredis library confirm that the extension explicitly checks for connection status and throws these exceptions to signal that the server has gone away [1][6][7].

immediately from recordFailure() if incr(), expire(), or setex() fails, and
return immediately from clear() if del() fails, preserving fail-open
authentication behavior. Affected site
backend/app/Helpers/AccountLockoutHelper.php lines 53-53 requires the ttl()
fallback; lines 74-80 require handling recordFailure() command failures; line 94
requires handling del() failure.

Summary
Found during an internal security review of the authentication flow.
ForgotPasswordControllerreturnedEMAIL_DOES_NOT_EXISTfor unknown emails, letting an attacker enumerate the entire user base (including admins) by scripting requests. Now returns an identical generic response whether or not the account exists.LoginControllerdistinguishedINVALID_USERNAME_OR_EMAILvsINVALID_PASSWORD. Unified into a singleINVALID_CREDENTIALSresponse, plus a dummypassword_verify()call on the unknown-user path to reduce the timing gap between the two branches.RateLimitMiddleware), so credential stuffing / 2FA brute-forcing could bypass it entirely via IP rotation (proxy/botnet). Added a newAccountLockoutHelper(Redis-backed, fails open if Redis is unavailable - consistent with the existing rate limiter) and wired it into both login (10 attempts / 15 min) and 2FA verification (5 attempts / 15 min, tighter since a 6-digit TOTP code has a much smaller keyspace).Testing
Tested live against a running instance:

RateLimitMiddleware, so both layers apply together.Summary by CodeRabbit
