SQL injection in the ‘two_steps_auth_code’ parameter processed by the ‘twoStepsAuthVerification’ function within the ‘/user-login’ endpoint. The two-factor authentication (2FA) functionality can be accessed without prior authentication, allowing unauthenticated attackers to execute arbitrary SQL queries on the backend database. A successful exploit could lead to database enumeration, the unauthorised creation of privileged users, the modification or deletion of critical information, and denial-of-service conditions.
