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
Cleartext Storage of Sensitive Information in GUI vulnerability in Mitsubishi Electric GENESIS64 versions 10.97.3 and prior, Mitsubishi Electric ICONICS Suite versions 10.97.3 and prior, Mitsubishi Electric MobileHMI versions 10.97.3 and prior, Mitsubishi Electric Hyper Historian versions 10.97.3 and prior, Mitsubishi Electric AnalytiX versions 10.97.3 and prior, Mitsubishi Electric GENESIS versions 11.02 and prior, Mitsubishi Electric MC Works64 all versions, Mitsubishi Electric Iconics Digital Solutions GENESIS64 versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions ICONICS Suite versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions MobileHMI versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions Hyper Historian versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions AnalytiX versions 10.97.3 and prior, and Mitsubishi Electric Iconics Digital Solutions GENESIS versions 11.02 and prior allows a local attacker to disclose the SQL Server credentials displayed in plain text in the GUI of the Hyper Historian Splitter feature by exploiting this vulnerability, when SQL authentication is used for the SQL Server authentication. As a result, the unauthorized attacker could access the SQL Server and disclose, tamper with, or destroy data on the server, potentially cause a denial-of-service (DoS) condition on the system.

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 cleartext storage of sensitive information vulnerability exists in the Hyper Historian Splitter feature GUI across multiple Mitsubishi Electric products. SQL Server credentials are displayed in plain text when SQL authentication is used, allowing a local attacker with system access to view and steal these credentials.

MitigationUpdate to patched versions when available. Until then, restrict local access to the affected systems, use Windows authentication instead of SQL authentication where possible, and monitor for unauthorized access to the SQL Server.

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. Verify Hyper Historian Splitter GUI is present
    Locate the Hyper Historian Splitter GUI component in the affected product installation. This is typically found in the product's configuration or administration interface under a Splitter or Hyper Historian section.
    Affected if The Splitter GUI feature exists and is accessible in the installation.
  2. Identify SQL authentication configuration
    Check the Splitter GUI configuration for database connection settings. Look for fields specifying SQL Server authentication method - typically labeled as 'SQL Authentication', 'SQL Server Authentication', or showing username/password fields rather than Windows integrated security.
    Affected if SQL Server authentication is selected/configured (username and password fields are populated or editable).
  3. Locate stored SQL credentials
    Examine the configuration files, registry, or GUI panels where SQL connection strings are stored. In the Splitter GUI, navigate to the database connection settings panel and observe if credentials are displayed or editable.
    Affected if SQL username and password fields are visible or stored in the configuration.
  4. Check for plain text password display
    In the Splitter GUI SQL connection configuration, observe whether the password field shows cleartext characters or is masked (showing dots/asterisks). Also check any exported configuration files for unencrypted password strings.
    Affected if The password field displays in cleartext or configuration files contain unencrypted SQL passwords.

A user is affected if the Hyper Historian Splitter GUI is present and SQL authentication is configured with credentials that are visible in plain text rather than masked or encrypted.

Mitigation

Update to patched versions when available. Until then, restrict local access to the affected systems, use Windows authentication instead of SQL authentication where possible, and monitor for unauthorized access to the SQL Server.
