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 installed Hitachi Command Suite componentsLocate Hitachi Command Suite installations on the system. Common installation directories include C:\Program Files\Hitachi or /opt/hitachi. Check for Device Manager, Tiered Storage Manager, Replication Manager, Tuning Manager, or Compute Systems Manager components.Affected if Any of the five affected products (Device Manager, Tiered Storage Manager, Replication Manager, Tuning Manager, or Compute Systems Manager) are installed on the system.
-
Determine installed versionLocate the version information for the installed component. Version details are typically found in the product's about section, installation logs, or version file within the product directory.Affected if The installed version is 7.x, or 8.x but earlier than 8.6.5-00 for Device Manager, Tiered Storage Manager, Replication Manager, or Tuning Manager; or earlier than 8.7.0-00 for Compute Systems Manager.
-
Verify web interface accessibilityCheck if the Hitachi Command Suite web interface port is open and listening. Common ports are 8081 or 23451. Use netstat or a port scanner to confirm the management interface is accessible over the network.Affected if The web interface port is open and exposed to the network, allowing unauthenticated access to internal system information.
If any Hitachi Command Suite component (Device Manager, Tiered Storage Manager, Replication Manager, Tuning Manager, or Compute Systems Manager) is installed with a version in the vulnerable range AND the web interface is network-accessible, the environment is affected by this CVE.
