Siemens SIMATIC S7-1200 CPU PLC devices with firmware before 4.0 allow remote attackers to cause a denial of service (defect-mode transition) via crafted PROFINET packets, a different vulnerability than CVE-2014-2253.

Security readout for executives and security teams

This affects Siemens SIMATIC S7-1200 PLC CPUs running firmware before 4.0. A remote attacker able to send crafted PROFINET traffic could force the controller into defect mode, causing a denial of service. That matters because PLC disruption can stop or impair industrial processes. Exposure is most likely where SIMATIC S7-1200 CPUs with firmware before 4.0 are reachable from networks that can send PROFINET traffic. Internet exposure is not stated in the sources and should not be assumed. Prioritize assessment if S7-1200 PLCs support production, safety-adjacent, or uptime-critical processes. The main business risk is process disruption, not data theft. Urgency depends on whether affected controllers remain below firmware 4.0 and are reachable from untrusted or broad internal networks. Mitigation focus: Inventory SIMATIC S7-1200 CPU firmware versions.; Prioritize vendor-guided upgrades for firmware before 4.0.; Review Siemens SSA-654382 for current remediation details..
