CVE-2025-6892
Full vulnerability record from the local CVENow database.
Description
An Incorrect Authorization vulnerability has been identified in Moxa’s network security appliances and routers. A flaw in the API authentication mechanism allows unauthorized access to protected API endpoints, including those intended for administrative functions. This vulnerability can be exploited after a legitimate user has logged in, as the system fails to properly validate session context or privilege boundaries. An attacker may leverage this flaw to perform unauthorized privileged operations. While successful exploitation can severely impact the confidentiality, integrity, and availability of the affected device itself, there is no loss of confidentiality or integrity within any subsequent systems.

"value": "Se ha identificado una vulnerabilidad de autorización incorrecta en los dispositivos de seguridad de red y routers de Moxa. Una falla en el mecanismo de autenticación de la API permite el acceso no autorizado a los puntos finales de la API protegidos, incluidos aquellos destinados a funciones administrativas. Esta vulnerabilidad puede ser explotada después de que un usuario legítimo haya iniciado sesión, ya que el sistema no valida correctamente el contexto de la sesión o los límites de privilegios. Un atacante puede aprovechar esta falla para realizar operaciones privilegiadas no autorizadas. Si bien la explotación exitosa puede impactar gravemente la confidencialidad, integridad y disponibilidad del propio dispositivo afectado, no hay pérdida de confidencialidad o integridad dentro de ningún sistema subsiguiente."
