Browse all 1674 CVE security advisories affecting Siemens. AI-powered Chinese analysis, POCs, and references for each vulnerability.
Siemens operates as a global industrial technology conglomerate, primarily manufacturing automation systems, power infrastructure, and medical imaging devices. Its extensive portfolio of programmable logic controllers and human-machine interfaces frequently exposes critical vulnerabilities, with recorded Common Vulnerabilities and Exposures numbering in the thousands. Historically, these systems have suffered from remote code execution flaws, buffer overflows, and insecure default configurations that allow unauthorized privilege escalation. Notable incidents include the Stuxnet worm, which exploited Siemens PLCs to disrupt Iranian nuclear centrifuges, highlighting the severe physical consequences of digital compromise in industrial control environments. The company has since strengthened its security posture through firmware updates and secure-by-design principles, yet legacy devices remain vulnerable due to long operational lifecycles and limited patching capabilities in isolated networks.
