CVE-2014-2251 describes a low-entropy random number generator in Siemens SIMATIC S7-1500 CPU PLC devices with firmware prior to version 1.5.0. This flaw allows remote attackers to more easily bypass cryptographic protections and hijack sessions. With a CVSS score of 8.3, this vulnerability is considered high severity due to its network-based attack vector, medium complexity, and potential for partial confidentiality, integrity, and complete availability impact. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
