Descriptions

The ComputePassword function in the Schneider Electric Quantum Ethernet Module on the NOE 771 device (aka the Quantum 140NOE771* module) generates the password for the fwupgrade account by performing a calculation on the MAC address, which makes it easier for remote attackers to obtain access via a (1) ARP request message or (2) Neighbor Solicitation message.

La función ComputePassword del módulo Schneider Electric Quantum Ethernet del dispositivo NOE 771 (modulo Quantum 140NOE771*) genera la contraseña de la cuenta fwupgrade realizando un cálculo con la dirección MAC, lo que facilita a atacantes remotos obtener acceso a través de (1) un mensaje de petición ARP o (2) un mensaje de descubrimiento de elementos en la misma red ("Neighbor Solicitation").
