Descriptions
The random-number generator on Siemens SIMATIC S7-1200 CPU PLC devices with firmware before 4.0 does not have sufficient entropy, which makes it easier for remote attackers to defeat cryptographic protection mechanisms and hijack sessions via unspecified vectors, a different vulnerability than CVE-2014-2251.
El generador de números aleatorios en dispositivos de Siemens SIMATIC S7-1200 CPU PLC con firmware anterior a 4.0 no tiene suficiente entropía, lo que facilita a atacantes remotos anular mecanismos de protección criptográfica y secuestrar sesiones a través de vectores no especificados, una vulnerabilidad diferente a CVE-2014-2251.
