CVE-2024-21543

Versions of the package djoser before 2.3.0 are vulnerable to Authentication Bypass when the authenticate() function fails. This is because the system falls back to querying the database directly, granting access to users with valid credentials, and eventually bypassing custom authentication checks such as two-factor authentication, LDAP validations, or requirements from configured AUTHENTICATION_BACKENDS.

Summary		(es) Las versiones del paquete djoser anteriores a la 2.3.0 son vulnerables a la omisión de autenticación cuando falla la función authenticate(). Esto se debe a que el sistema recurre a consultar directamente la base de datos, otorgando acceso a los usuarios con credenciales válidas y, finalmente, omitiendo las comprobaciones de autenticación personalizadas, como la autenticación de dos factores, las validaciones LDAP o los requisitos de AUTHENTICATION_BACKENDS configurados.
