CVE-2025-65094

WBCE CMS is a content management system. Prior to version 1.6.4, a low-privileged user in WBCE CMS can escalate their privileges to the Administrators group by manipulating the groups[] parameter in the /admin/users/save.php request. The UI restricts users to assigning only their existing group, but server-side validation is missing, allowing attackers to overwrite their group membership and obtain full administrative access. This results in a complete compromise of the CMS. This issue has been patched in version 1.6.4.

Summary		(es) WBCE CMS es un sistema de gestión de contenido. Versiones anteriores a la versión 1.6.4, un usuario con privilegios bajos en WBCE CMS puede escalar sus privilegios al grupo de Administradores manipulando el parámetro groups[] en la solicitud /admin/users/save.php. La interfaz de usuario restringe a los usuarios a asignar solo su grupo existente, pero falta validación del lado del servidor, lo que permite a los atacantes sobrescribir su membresía de grupo y obtener acceso administrativo completo. Esto resulta en un compromiso completo del CMS. Este problema ha sido parcheado en la versión 1.6.4.
