CVE-2025-6893
Full vulnerability record from the local CVENow database.
Description
An Execution with Unnecessary Privileges vulnerability has been identified in Moxa’s network security appliances and routers. A flaw in broken access control has been identified in the /api/v1/setting/data endpoint of the affected device. This flaw allows a low-privileged authenticated user to call the API without the required permissions, thereby gaining the ability to access or modify system configuration data. Successful exploitation may lead to privilege escalation, allowing the attacker to access or modify sensitive system settings. While the overall impact is high, there is no loss of confidentiality or integrity within any subsequent systems.

"value": "Una vulnerabilidad de ejecución con privilegios innecesarios ha sido identificada en los dispositivos de seguridad de red y routers de Moxa. Una falla en el control de acceso roto ha sido identificada en el endpoint /api/v1/setting/data del dispositivo afectado. Esta falla permite a un usuario autenticado con bajos privilegios llamar a la API sin los permisos requeridos, obteniendo así la capacidad de acceder o modificar datos de configuración del sistema. La explotación exitosa puede llevar a la escalada de privilegios, permitiendo al atacante acceder o modificar configuraciones sensibles del sistema. Si bien el impacto general es alto, no hay pérdida de confidencialidad o integridad dentro de ningún sistema subsiguiente."
