Description

Pterodactyl is a free, open-source game server management panel. From 1.7.0 until 1.13.0, the authentication rate limiter defined in RouteServiceProvider::configureRateLimiting() applied a single global bucket to the login and two-factor checkpoint endpoints instead of keying by IP or account: the fall-through Limit::perMinute(10) covering POST /auth/login and POST /auth/login/checkpoint omitted ->by(), so Laravel derived a constant cache key (md5('authentication')) shared by every request. An unauthenticated attacker sending roughly ten requests per minute from a single IP, most cheaply against the checkpoint endpoint (which has no reCAPTCHA), exhausts the shared counter and causes HTTP 429 for every user attempting to log in or complete two-factor authentication, a panel-wide authentication denial of service that also locks out administrators. This issue is fixed in version 1.13.0.
