FKIE_CVE-2023-4213

Vulnerability from fkie_nvd - Published: 2023-09-13 03:15 - Updated: 2026-04-08 18:18
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
The Simplr Registration Form Plus+ plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 2.4.5. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with subscriber-level permissions or above to change user passwords and potentially take over administrator accounts.

      "value": "El complemento Simplr Registration Form Plus+ para WordPress es vulnerable a referencias directas a objetos inseguros en versiones hasta la 2.4.5 inclusive. Esto se debe a que el complemento proporciona acceso controlado por el usuario a los objetos, lo que le permite omitir la autorizaci\u00f3n y acceder a los recursos del sistema. Esto hace posible que atacantes autenticados con permisos de nivel de suscriptor o superiores cambien las contrase\u00f1as de los usuarios y potencialmente se apoderen de cuentas de administrador."
