Who should care

Organizations operating Hitachi Energy MicroSCADA X SYS600 version 10.5 or earlier in industrial control environments, particularly those with web-accessible SCADA interfaces. Security teams responsible for OT/ICS infrastructure, network administrators managing SCADA deployments, and compliance officers tracking CISA ICS advisories should prioritize assessment and patching.

Technical summary

The vulnerability exists in the web application component of MicroSCADA Pro/X SYS600 where an HTTP parameter accepts URL values without proper validation. An attacker can craft a request with a malicious URL in this parameter, causing the application to redirect the user's browser to an attacker-controlled site. This enables phishing attacks where users may be presented with fake login pages to harvest credentials. The attack requires user interaction (clicking a crafted link) and network access to the web interface. CVSS 3.1 score 4.3 (MEDIUM) reflects the need for user interaction and limited impact scope.

Defensive priority

Recommended defensive actions

  • Apply vendor patches: Update MicroSCADA X SYS600 to version 10.5 vulnerability patch 2025_01 or upgrade to version 10.6
  • Implement network segmentation to limit exposure of SCADA web interfaces
  • Configure web application firewalls to filter malicious redirect parameters
  • Review and apply CISA ICS recommended practices for defense-in-depth
  • Monitor for suspicious redirect requests in web access logs
  • Educate users on phishing risks and verify URLs before entering credentials
