      "value": "Primakon Pi Portal 1.0.18 REST /api/v2/user/register endpoint suffers from a Broken Access Control vulnerability. The endpoint fails to implement any authorization checks, allowing unauthenticated attackers to perform POST requests to register new user accounts in the application's local database. This bypasses the intended security architecture, which relies on an external Identity Provider for initial user registration and assumes that internal user creation is an administrative-only function. This vector can also be chained with other vulnerabilities for privilege escalation and complete compromise of application. This specific request can be used to also enumerate already registered user accounts, aiding in social engineering or further targeted attacks."

      "value": "El endpoint REST /api/v2/user/register de Primakon Pi Portal 1.0.18 padece de una vulnerabilidad de control de acceso roto. El endpoint no implementa ninguna comprobación de autorización, lo que permite a atacantes no autenticados realizar solicitudes POST para registrar nuevas cuentas de usuario en la base de datos local de la aplicación. Esto elude la arquitectura de seguridad prevista, que se basa en un proveedor de identidad externo para el registro inicial de usuarios y asume que la creación interna de usuarios es una función exclusiva de administración. Este vector también puede encadenarse con otras vulnerabilidades para la escalada de privilegios y el compromiso completo de la aplicación. Esta solicitud específica también puede utilizarse para enumerar cuentas de usuario ya registradas, lo que ayuda en la ingeniería social o en ataques dirigidos adicionales."
