security: secure session cookie flags + expiring password-reset tokens - #225
Crackhead-gsk wants to merge 2 commits 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 secure remember-token cookies, expiring password-reset tokens, generic credential errors, and Redis-backed per-account lockouts for login and 2FA verification. ChangesAuthentication hardening

- Line 98: Update the invalid-token branch in AuthLogoutController so
SessionCookieHelper::clear() executes before returning when
User::getUserByRememberToken() returns null. Preserve the existing
cookie-clearing behavior for valid tokens, ensuring both logout paths remove the
remember_token.
In `@backend/app/Controllers/User/Auth/LoginController.php`:
- Line 246: Update the OpenAPI declaration associated with LoginController to
include a 429 response contract for the lockout path, matching the existing
response documentation structure and preserving all current response
definitions.
- Around line 243-248: Update the lockout response in the login flow of
LoginController so unauthenticated requests receive the same generic
invalid-credentials response as unknown accounts, removing the ACCOUNT_LOCKED
code, timing message, and retry_after metadata from the public response while
preserving internal lockout enforcement.
- Line 272: Update the known-account failure handling around LoginController and
AccountLockoutHelper::recordFailure so repeated failed passwords no longer
create a universal account lockout that denies the owner authentication. Replace
the hard lock with an escalating challenge or delay applied without blocking
every client, while preserving password verification and addressing
distributed-request abuse rather than relying only on IP-based limits.
In `@backend/app/Helpers/AccountLockoutHelper.php`:
- Around line 74-76: Update the counter-increment logic in AccountLockoutHelper
so the initial creation/increment of countKey and its ATTEMPT_WINDOW_SECONDS
expiry occur atomically, using the existing Redis client and preserving the
current first-increment-only TTL behavior. Replace the separate incr and expire
sequence while keeping subsequent increments from resetting the window.
- Around line 53-55: Extend the \Throwable handling in AccountLockoutHelper so
Redis command calls, including ttl(), incr(), expire(), setex(), and del(), are
covered by the same fail-open boundary as getRedis(). Ensure command failures
return the helper’s existing safe fallback rather than propagating exceptions
into authentication, while preserving normal successful Redis behavior.

Clear the cookie on the invalid-token path.
User::getUserByRememberToken() can return null, and that branch returns before this SessionCookieHelper::clear() call. Logout then leaves a stale remember_token in the browser. Move the clear before that return so valid and invalid tokens are both removed.

Keep lockout state indistinguishable before authentication.
A known account returns ACCOUNT_LOCKED with retry_after, while an unknown account returns INVALID_CREDENTIALS. This exposes account existence through the public login endpoint.
Return the same generic credential response during lockout. Do not expose lockout metadata before authentication.

Denial of Service (CWE-799)
Reachability: External · Exploitability: Moderate
Do not make a known account identifier an availability kill switch.
For a known account, ten failed passwords within 15 minutes create a 15-minute account lock before password verification. An attacker can repeat this cycle and block the account owner from logging in. Replace the hard lock with an escalating challenge or delay that does not deny authentication to every client. IP-only controls do not stop distributed requests.

phpredis official documentation Redis OPT_THROW_EXCEPTIONS connection failure command exception behavior
💡 Result:
In the phpredis extension, the behavior regarding connection failures and command exceptions is primarily governed by the library's internal handling of RedisException rather than a specific global option named OPT_THROW_EXCEPTIONS [1][2][3]. Official documentation and implementation details clarify the following: 1. Connection Failures: Phpredis is designed to throw a RedisException when it cannot reach the Redis server, such as during connectivity issues, if the service is down, or if the host is overloaded [1][2][4]. This occurs regardless of optional configuration flags because it is the core mechanism for handling unreachable servers [1][5]. 2. Command Exceptions: For operations involving existing connections (e.g., executing commands like GET or SET), phpredis typically returns FALSE if an issue occurs that does not involve a loss of server connectivity (such as a key not existing or an invalid command) [1][2][4]. 3. Regarding OPT_THROW_EXCEPTIONS: There is no widely documented or standard constant named Redis::OPT_THROW_EXCEPTIONS within the phpredis extension [6]. While older discussions or confusion may exist, the extension consistently relies on throwing RedisException for fundamental connection failures and returning FALSE for routine command errors [1][3]. For developers seeking to handle errors robustly, the standard practice is to wrap Redis operations in try-catch blocks to capture RedisException for connection-related issues [1][7], and to check for boolean FALSE return values for command-specific logic errors [1][4].

Catch Redis command failures, not only connection setup.
getRedis() protects only App::getRedisConnection(). phpredis can throw RedisException when the returned \Redis connection becomes unreachable, so the later ttl(), incr(), expire(), setex(), and del() calls can abort authentication instead of failing open. Wrap these calls in the same \Throwable boundary. Do not let one dead Redis socket turn this fail-open path into another Friday 500.

Make counter expiry atomic before this Friday-grade lockout ships.
incr() creates $countKey without a TTL. If the connection fails before the separate expire() call, the count persists indefinitely. Later failures can recreate the lockout immediately after each lockout expires, until successful authentication calls clear(). Use a Lua script or transaction design that preserves the first-increment condition while setting the TTL atomically.

This branch is stacked on #224 (it includes that commit plus the new one below), since both touch the same auth controllers. GitHub will show both diffs until #224 merges - the actual new change here is the
SessionCookieHelper+ reset-token-expiry commit.Summary
Found during an internal security review of the authentication flow.
remember_tokenwas set via the legacy 4-argumentsetcookie(name, value, expire, path)signature in 6 places (login, 2FA verify, register, logout x2, account deletion), which sets none ofHttpOnly,Secure, orSameSite. That leaves the session cookie readable by JavaScript (XSS -> session hijack) and sendable cross-site. Added aSessionCookieHelper(auto-detects HTTPS via$_SERVER[HTTPS]orX-Forwarded-Protobehind a reverse proxy) and switched every call site to it: now setsHttpOnly,Secure(when on HTTPS), andSameSite=Lax.ForgotPasswordControllergenerated a bare random token stored in the sharedmail_verifycolumn with no expiry - if an old reset email/link leaked later (proxy logs, mail client cache, etc.), it would still work indefinitely. Tokens are now generated as<64 hex chars>.<unix_expiry>(1 hour TTL) and bothResetPasswordControllerendpoints (validate + reset) check the embedded expiry, rejecting and invalidating expired tokens instead of accepting them forever. No DB migration needed sincemail_verifyis alreadyVARCHAR(255).Testing
