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 QNAP Helpdesk is installed
    Locate the Helpdesk application on the QNAP device - typically found in the App Center or via CLI checking for helpdesk processes
    Affected if Helpdesk is not installed or not running - no further action needed
  2. Identify installed Helpdesk version
    Access QTS admin panel, navigate to App Center > Helpdesk, or check the version via QNAP CLI tools if available. Compare the version number to the 3.0.0 threshold
    Affected if Installed version is below 3.0.0 - system is vulnerable
  3. Verify log access endpoint accessibility
    Attempt to access the system log viewing functionality within Helpdesk without authentication. Check if URL endpoints like /helpdesk/logs or similar paths are reachable without login credentials
    Affected if Logs are accessible without authentication - actively exploited condition
  4. Inspect Helpdesk configuration files
    Locate Helpdesk configuration files in the QNAP system (typically in /share/HDA_DATA/.qpkg/Helpdesk or similar paths) and examine access control settings
    Affected if Access control settings are absent, misconfigured, or allow anonymous/public access

If QNAP Helpdesk is installed and the version is below 3.0.0, the system is affected by this information disclosure vulnerability.
