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.

Security readout for executives and security teams

Some Siemens SIMATIC S7-1200 PLCs running firmware before 4.0 used a weak random-number generator. That can weaken cryptographic protections and make session hijacking easier for a remote attacker. The public bundle does not provide a CVSS score, detailed attack path, or evidence of active exploitation. Exposure is likely limited to Siemens SIMATIC S7-1200 CPU PLCs running firmware before 4.0, especially where PLC management or communication paths are reachable from untrusted networks. Prioritize if S7-1200 PLCs support safety, production, or critical operations, or if they are remotely reachable. Otherwise handle through planned industrial control system maintenance. Mitigation focus: Identify all Siemens SIMATIC S7-1200 CPU PLCs and record firmware versions.; Review Siemens SSA-654382 and ICS-CERT ICSA-14-079-02 guidance.; Update affected PLC firmware to version 4.0 or later where supported..
