CVE-2025-39204
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability exists in the Web interface of the MicroSCADA X SYS600 product. The filtering query in the Web interface can be malformed, so returning data can leak unauthorized information to the user.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMicroSCADA X SYS600 web interface contains a filtering query vulnerability where malformed queries can bypass access controls and leak unauthorized information to users. The vulnerability stems from insufficient input validation or improper query construction in the web interface's data filtering mechanism.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if MicroSCADA X SYS600 is installedLocate the installation directory or running service for Hitachi Energy MicroSCADA X SYS600 on the target systemAffected if The product is not found on the system, then the environment is not affected
-
Determine the installed versionCheck the installed version of MicroSCADA X SYS600 and compare it to the affected range: versions 10.0 through 10.6.xAffected if The installed version falls within >= 10.0 and < 10.7
-
Verify the web interface is enabledConfirm the SYS600 web interface service or component is running and accessibleAffected if The web interface is disabled or not accessible, then the vulnerability cannot be exploited
-
Inspect filtering mechanism configurationExamine the web interface data filtering configuration files or settings for access control parametersAffected if Filtering or access control settings are present but can be bypassed with malformed queries
-
Test for unauthorized data accessSubmit malformed filtering queries through the web interface to verify if access controls can be bypassedAffected if Malformed queries return data that the requesting user should not have permission to view
The environment is affected if MicroSCADA X SYS600 version 10.0 through 10.6.x is installed with the web interface enabled, and malformed filtering queries can bypass access controls to leak unauthorized data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped10.7
Implement proper input validation and query parameterization in the web interface filtering logic. Apply principle of least privilege to ensure users can only access data they are authorized to view, regardless of query manipulation.
MicroSCADA X SYS600 version 10.7 or later
- Identify the current installed version of MicroSCADA X SYS600 by checking the system information or About section
- Backup all configuration files and databases before performing any upgrade
- Review Hitachi Energy's official release notes for version 10.7 to understand changes and prerequisites
- Download MicroSCADA X SYS600 version 10.7 or later from Hitachi Energy's official support portal
- Execute the upgrade installer following Hitachi Energy's documented upgrade procedure
- After upgrade, verify the web interface filtering functionality works correctly
- Test that the information exposure vulnerability is remediated by attempting various malformed query inputs
- Restore configuration from backup if needed and validate system operation
