Improper access control to a data point of the affected product could allow an unauthenticated remote user to escalate its privileges in the context of SIMATIC WinCC OA V3.14. This vulnerability could be exploited by an attacker with network access to port 5678/TCP of the SIMATIC WinCC OA V3.14 server. Successful exploitation requires no user privileges and no user interaction. This vulnerability could allow an attacker to compromise integrity and availability of the SIMATIC WinCC OA system. At the time of advisory publication no public exploitation of this vulnerability was known."

El control de acceso incorrecto a un punto de datos del producto afectado podría permitir que un usuario remoto no autenticado escale sus privilegios en el contexto de SIMATIC WinCC OA V3.14. Esta vulnerabilidad podría ser explotada por un atacante con acceso de red al puerto 5678/TCP del servidor SIMATIC WinCC OA V3.14. Su explotación con éxito no requiere privilegios de usuario ni interacción. Esta vulnerabilidad podría permitir que un atacante comprometa la integridad y disponibilidad del sistema SIMATIC WinCC OA. En el momento de la publicación del advisory, no se conoce ninguna explotación pública de la vulnerabilidad."
