Descriptions

Wago 750 Series PLCs with firmware version 10 and prior include a remote attack may take advantage of an improper implementation of the 3 way handshake during a TCP connection affecting the communications with commission and service tools. Specially crafted packets may also be sent to Port 2455/TCP/IP, used in Codesys management software, which may result in a denial-of-service condition of communications with commissioning and service tools.

Los PLC Wago 750 Series, con versiones de firmware 10 y anteriores, incluyen un ataque remoto que podría aprovecharse de una implementación incorrecta de la negociación a tres bandas durante una conexión TCP, lo que afecta a las comunicaciones con las herramientas de comisión y servicio. Los paquetes especialmente manipulados también podrían enviarse al puerto 2455/TCP/IP, empleado en el software de gestión Codesys, lo que podría resultar en una condición de denegación de servicio de las comunicaciones con las herramientas de comisión y servicio.
