Summary

This vulnerability affects Hitachi Energy MicroSCADA Pro X SYS600 due to improper input validation and insufficient access controls (CWE-20, CWE-269, CWE-284, CWE-241). An attacker with low-privilege user credentials can exploit the ICCP feature to execute arbitrary scripts, causing the SYS600 application to fail to start or enter a denial-of-service condition. Successful exploitation requires network access and low-level credentials, but the attack complexity is low. Systems running SYS600 version 9.4 FP2 Hotfix 4 and earlier, or version 10.3.1 and earlier are affected. Version 10.4 and later include the fix.

What this means
What could happen
An attacker with low-level credentials could execute arbitrary scripts on the SYS600 system, potentially stopping the application, causing denial of service, or altering process logic. This could disrupt energy distribution operations.
Who's at risk
Energy utilities operating Hitachi Energy MicroSCADA Pro X SYS600 supervisory control and data acquisition (SCADA) systems, particularly those running versions 9.4 FP2 Hotfix 4 and earlier, or 10.3.1 and earlier. Any SYS600 system with ICCP enabled is at risk.
How it could be exploited
An attacker on the network with local/low-privilege user credentials can send a specially crafted request to the SYS600 system to trigger improper input validation, enabling script execution. The attack is remotely exploitable over the network and requires low complexity to execute.
Prerequisites
  • Network access to the SYS600 system
  • Low-privilege user credentials (local or remote login)
  • ICCP feature enabled (default or explicitly configured)
