Summary
An authentication bypass vulnerability exists in the WordPress Pie Register plugin ≤ 3.7.1.4 that allows unauthenticated attackers to impersonate arbitrary users by submitting a crafted POST request to the login endpoint. By setting social_site=true and manipulating the user_id_social_site parameter, an attacker can generate a valid WordPress session cookie for any user ID, including administrators. Once authenticated, the attacker may exploit plugin upload functionality to install a malicious plugin containing arbitrary PHP code, resulting in remote code execution on the underlying server.

      "value": "Existe una vulnerabilidad de omisi\u00f3n de autenticaci\u00f3n en el complemento de WordPress Pie Register (versi\u00f3n ? 3.7.1.4) que permite a atacantes no autenticados suplantar la identidad de usuarios arbitrarios mediante el env\u00edo de una solicitud POST manipulada al endpoint de inicio de sesi\u00f3n. Al establecer social_site=true y manipular el par\u00e1metro user_id_social_site, un atacante puede generar una cookie de sesi\u00f3n de WordPress v\u00e1lida para cualquier ID de usuario, incluidos los administradores. Una vez autenticado, el atacante puede explotar la funcionalidad de carga del complemento para instalar un complemento malicioso con c\u00f3digo PHP arbitrario, lo que provoca la ejecuci\u00f3n remota de c\u00f3digo en el servidor subyacente."
