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 · unedited
A vulnerability exists in in the Monitor Pro interface of the MicroSCADA X SYS600 product. An authenticated user with low privileges can see and overwrite files causing information leak and data corruption.

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 confidence

A path traversal or improper authorization vulnerability exists in the Monitor Pro interface of MicroSCADA X SYS600. An authenticated user with low privileges can read (see) and write (overwrite) arbitrary files on the system, leading to information disclosure and data corruption.

MitigationImplement proper file system access controls and authorization checks in the Monitor Pro interface to ensure low-privilege users cannot read or write files outside their intended scope.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed MicroSCADA version
    Query the system or check the product documentation for the installed version of Hitachienergy MicroSCADA X SYS600. This is typically available through the system information panel, installation directory, or product-specific command-line utility.
    Affected if The installed version is 10.0 or higher but lower than 10.7
  2. Confirm Monitor Pro interface is accessible
    Verify that the Monitor Pro interface component is installed and enabled on the system. Check the product's component list or configuration to confirm Monitor Pro is present.
    Affected if Monitor Pro interface is installed and accessible to users
  3. Review user account privileges
    Examine the user account configuration and privilege levels assigned within the MicroSCADA system. Identify accounts with low-privilege access to the Monitor Pro interface.
    Affected if Low-privilege user accounts exist with access to Monitor Pro
  4. Test file access boundaries
    Using a low-privilege authenticated account, attempt to access files outside the intended Monitor Pro working directory through the interface. This may involve checking if the application restricts file paths to authorized directories.
    Affected if The interface allows reading or writing files outside the expected scope for low-privilege users
  5. Inspect file system permissions
    Review the file system permissions and access control lists (ACLs) on the system to determine whether low-privilege accounts have been granted broader file access than intended.
    Affected if File permissions allow low-privilege users to read or overwrite arbitrary system files

You are affected if running MicroSCADA X SYS600 version 10.0 through 10.6 with Monitor Pro enabled and low-privilege users can access files outside their intended directory scope.

dbcve · scoped
Upgrade available Upgrade to 10.7 or later
Fixed in 10.7
Interim mitigation

Implement proper file system access controls and authorization checks in the Monitor Pro interface to ensure low-privilege users cannot read or write files outside their intended scope.

Recommended fix Moderate confidence

MicroSCADA X SYS600 version 10.7 or later

  1. 1. Verify current MicroSCADA X SYS600 version by accessing the system information panel or using the version check utility
  2. 2. Create a complete backup of the current system configuration, including all project files, databases, and settings
  3. 3. Schedule the upgrade during a planned maintenance window to minimize operational impact
  4. 4. Download the MicroSCADA X SYS600 version 10.7 or later from Hitachi Energy's official support portal at publisher.hitachienergy.com
  5. 5. Review all release notes and upgrade documentation for version 10.7 before proceeding
  6. 6. Execute the installer with administrative privileges, following the documented installation procedure
  7. 7. After installation, verify that the Monitor Pro interface properly enforces privilege boundaries for low-privilege users
  8. 8. Confirm that low-privilege users can no longer access or overwrite files outside their authorized scope
Caveat Review release notes for potential impacts on custom configurations, third-party integrations, or existing project files when upgrading to version 10.7
