Descriptions

A vulnerability has been identified in EN100 Ethernet module DNP3 IP variant (All versions), EN100 Ethernet module IEC 104 variant (All versions), EN100 Ethernet module IEC 61850 variant (All versions < V4.40), EN100 Ethernet module Modbus TCP variant (All versions), EN100 Ethernet module PROFINET IO variant (All versions). Affected applications contains a memory corruption vulnerability while parsing specially crafted HTTP packets to /txtrace endpoint manupulating a specific argument. This could allow an attacker to crash the affected application leading to a denial of service condition

Se ha identificado una vulnerabilidad en la variante DNP3 IP del módulo EN100 Ethernet (Todas las versiones), la variante IEC 104 del módulo EN100 Ethernet (Todas las versiones), la variante IEC 61850 del módulo EN100 Ethernet (Todas las versiones anteriores a la versión V4.40), la variante Modbus TCP del módulo EN100 Ethernet (Todas las versiones), la variante PROFINET IO del módulo EN100 Ethernet (Todas las versiones). Las aplicaciones afectadas contienen una vulnerabilidad de corrupción de memoria mientras analizan paquetes HTTP especialmente diseñados para el punto final /txtrace que manupulan un argumento específico. Esto podría permitir a un atacante bloquear la aplicación afectada, provocando una condición de denegación de servicio.
