Descriptions

A vulnerability has been identified in DIGSI 4 (All versions < V4.92), EN100 Ethernet module DNP3 variant (All versions < V1.05.00), EN100 Ethernet module IEC 104 variant (All versions), EN100 Ethernet module IEC 61850 variant (All versions < V4.30), EN100 Ethernet module Modbus TCP variant (All versions), EN100 Ethernet module PROFINET IO variant (All versions). The device engineering mechanism allows an unauthenticated remote user to upload a modified device configuration overwriting access authorization passwords.

Se ha identificado una vulnerabilidad en Siemens DIGSI 4 (Todas las versiones anteriores a V4.92), EN100 Ethernet module DNP3 variant (Todas las versiones anteriores a V1.05.00), EN100 Ethernet module IEC 104 variant (Todas las versiones), EN100 Ethernet module IEC 61850 variant (Todas las versiones anteriores a V4.30), EN100 Ethernet module Modbus TCP variant (Todas las versiones), EN100 Ethernet module PROFINET IO variant (Todas las versiones). El mecanismo de ingeniería del dispositivo permite que un usuario remoto no autenticado suba una configuración de dispositivo modificada que sobrescriba las contraseñas de autorización de acceso
