Technologies Affected
  • Siemens SCALANCE X-200 IRT
  • Siemens SCALANCE X-200
  • Siemens Scalance X-300 Firmware 2.2.0
  • Siemens Scalance X-300 Firmware 2.3.1
  • Siemens Scalance X-300 Firmware 3.0.0
  • Siemens Scalance X-300 Firmware 3.3.1
  • Siemens Scalance X-300 Firmware 3.5.0
  • Siemens Scalance X-300 Firmware 3.5.1
  • Siemens Scalance X-300 Firmware 3.7.0
  • Siemens Scalance X-300 Firmware 3.7.2
  • Siemens Scalance X-300 Firmware 4.0

  • Block external access at the network boundary, unless external parties require service.
    If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.
  • Run all software as a nonprivileged user with minimal access rights.
    Run all non-administrative software as a non-administrative user with the least amount of privileges required to successfully operate. This will greatly reduce the potential damage that successful exploitation may achieve.
  • Deploy network intrusion detection systems to monitor network traffic for malicious activity.
    Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include suspicious URI sequences. Review webserver logs frequently.
  • Do not accept or execute files from untrusted or unknown sources.
    To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
  • Do not follow links provided by unknown or untrusted sources.
    Never follow links provided by unknown or untrusted sources.
