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
The product exposes a service that is intended for local only to all network interfaces without any authentication.

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 service that was designed to operate only on localhost (127.0.0.1) is being bound to all network interfaces (0.0.0.0), making it accessible from any network location. Combined with the absence of authentication, remote attackers can interact with this service directly.

MitigationBind the service to localhost only (127.0.0.1) or implement authentication and authorized access controls. Alternatively, use firewall rules to restrict access to trusted IPs or block external access.

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 MicroSCADA X Sys600 installation and version
    Locate the MicroSCADA X Sys600 installation directory and check the version file or executable properties. Common locations may include C:\Program Files\Hitachi Energy\MicroSCADA or similar. Look for version information in about dialogs, README files, or the main executable.
    Affected if Installed version is >= 10.2 and < 10.6
  2. Identify the vulnerable local service
    Review MicroSCADA X Sys600 documentation or configuration to identify which internal/local service is meant for loopback-only access. Common candidates include admin utilities, configuration services, or diagnostic tools.
    Affected if The identified service is present in the installation
  3. Check network binding configuration of the service
    Use system utilities such as netstat, ss, or similar to examine which network addresses the vulnerable service is bound to. Look for entries showing 0.0.0.0 or ::: port bindings versus 127.0.0.1 or ::1 localhost bindings.
    Affected if The service is bound to 0.0.0.0 or ::: (all interfaces) rather than 127.0.0.1 or ::1 only
  4. Verify remote accessibility
    From a different machine on the network, attempt to connect to the suspected service port on the target system's IP address (not localhost). Use tools like telnet, nc, or curl depending on the service type.
    Affected if The service responds to connections from remote network addresses
  5. Check firewall configuration
    Examine Windows Firewall or third-party firewall rules on the target system to see if the service port is allowed for inbound connections from remote addresses.
    Affected if Firewall permits inbound connections to the service from non-localhost sources

A system is affected if MicroSCADA X Sys600 version 10.2 through 10.5.x is installed and the local-only service is bound to 0.0.0.0 (all interfaces), making it accessible from remote network locations without authentication.

dbcve · scoped
Upgrade available Upgrade to 10.6 or later
Fixed in 10.6
Interim mitigation

Bind the service to localhost only (127.0.0.1) or implement authentication and authorized access controls. Alternatively, use firewall rules to restrict access to trusted IPs or block external access.

Recommended fix High confidence

Microscada X Sys600 version 10.6

  1. 1. Back up all current system configurations, project files, and databases according to Hitachi Energy backup procedures for Microscada X Sys600
  2. 2. Download Microscada X Sys600 version 10.6 from the official Hitachi Energy support portal (publisher.hitachienergy.com)
  3. 3. Verify the integrity of the downloaded package using checksums provided by Hitachi Energy
  4. 4. Test the upgrade in a non-production (staging) environment to ensure compatibility with your specific configuration
  5. 5. Schedule a maintenance window and notify all relevant stakeholders
  6. 6. Stop all Microscada services and ensure no active operations are running
  7. 7. Install version 10.6 following the official Hitachi Energy installation and upgrade documentation
  8. 8. Restore the backed-up configurations to the upgraded system
Caveat Review Hitachi Energy release notes for version 10.6 for any configuration changes, deprecated features, or migration requirements that may affect your specific deployment
