Descriptions
A denial of service vulnerability exists in Schneider Electric's MiCOM Px4x (P540 range excluded) with legacy Ethernet board, MiCOM P540D Range with Legacy Ethernet Board, and MiCOM Px4x Rejuvenated could lose network communication in case of TCP/IP open requests on port 20000 (DNP3oE) if an older TCI/IP session is still open with identical IP address and port number.
Existe una vulnerabilidad de denegación de servicio (DoS) en MiCOM Px4x (excepto el rango P540) con una placa Ethernet heredada, MiCOM P540D Range con una placa Ethernet heredada y MiCOM Px4x Rejuvenated, de Schneider Electric, que podrían perder la comunicación de red en caso de que TCP/IP abra peticiones en el puerto 20000 (DNP3oE) si una sesión TCP/IP más antigua siga abierta con una dirección IP y un número de puerto idénticos.
