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
Incorrect Default Permissions vulnerability in Hitachi Tuning Manager on Windows (Hitachi Tuning Manager server component) allows local users to read and write specific files.This issue affects Hitachi Tuning Manager: before 8.8.5-04.

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

Hitachi Tuning Manager server component on Windows has incorrect default file permissions that allow local users to read and write specific files. This is a local privilege escalation vulnerability where the installer sets overly permissive access control lists (ACLs) on configuration or data files, enabling standard user accounts to modify files they should not have access to.

MitigationUpgrade to Hitachi Tuning Manager version 8.8.5-04 or later which contains corrected file permissions, or manually review and restrict file system ACLs on the affected installation directory to follow least-privilege principles.

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. Confirm Hitachi Tuning Manager installation
    Open Windows Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product' in PowerShell to list installed software and look for Hitachi Tuning Manager entries
    Affected if The software is listed with a version earlier than 8.8.5-04
  2. Obtain exact installed version number
    Right-click the installed application in Programs and Features and select Properties, or check version information in the installation directory if known, to confirm the precise version string
    Affected if Version shown is below 8.8.5-04 (for example, 8.8.4 or earlier)
  3. Locate installation directory
    Right-click the application in Programs and Features and select Properties to view the Install Location path, or use Windows Explorer to find the Hitachi Tuning Manager program folder (typically under Program Files or Program Files (x86))
    Affected if Installation directory exists on the system and contains Hitachi Tuning Manager files
  4. Inspect file permissions on configuration or data files
    Right-click the installation folder, select Properties > Security tab, and examine the ACLs for user accounts. Pay attention to whether standard users (Authenticated Users, Users group) have Write or Modify permissions to configuration files, XML files, or data directories
    Affected if Standard non-admin user accounts are granted Write or Modify permissions on configuration or data files in the installation directory

You are affected if Hitachi Tuning Manager version is below 8.8.5-04 AND standard user accounts have write/modify access to configuration or data files in the installation directory.
