Descriptions
The random-number generator on Siemens SIMATIC S7-1500 CPU PLC devices with firmware before 1.5.0 does not have sufficient entropy, which makes it easier for remote attackers to defeat cryptographic protection mechanisms and hijack sessions via unspecified vectors.
El generador de números aleatorios en dispositivos de Siemens SIMATIC S7-1500 CPU PLC con firmware anterior a 1.5.0 no tiene suficiente entropía, lo que facilita a atacantes remotos derrotar mecanismos de protección criptográficos y secuestrar sesiones a través de vectores no especificados.
