Descriptions

A vulnerability has been identified in EN100 Ethernet module DNP3 variant (All versions), EN100 Ethernet module IEC 61850 variant (All versions < V4.37), EN100 Ethernet module IEC104 variant (All versions), EN100 Ethernet module Modbus TCP variant (All versions), EN100 Ethernet module PROFINET IO variant (All versions). An unauthorized user could exploit a buffer overflow vulnerability in the webserver. Specially crafted packets sent could cause a Denial-of-Service condition and if certain conditions are met, the affected devices must be restarted manually to fully recover. At the time of advisory publication no public exploitation of this security vulnerability was known.

Se ha identificado una vulnerabilidad en la variante DNP3 del módulo EN100 Ethernet (todas las versiones), la variante IEC 61850 del módulo EN100 Ethernet (todas las versiones anteriores a V4.37), la variante IEC104 del módulo EN100 Ethernet (todas las versiones), la variante Modbus TCP del módulo EN100 Ethernet (todas las versiones), la variante PROFINET IO del módulo EN100 Ethernet (todas las versiones). Un usuario no autorizado podría explotar una vulnerabilidad de desbordamiento del búfer en el servidor web. Los paquetes especialmente diseñados enviados podrían causar una condición de Denegación de Servicio y, si se cumplen determinadas condiciones, los dispositivos afectados deben ser reiniciados manualmente para recuperarse por completo. Al momento de la publicación del aviso, no era conocida la explotación pública de esta vulnerabilidad de seguridad.
