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 · high confidence

This is an unquoted service path vulnerability in QVR Smart Client on Windows systems. When executable paths containing spaces are not properly quoted, local authenticated administrators could potentially place malicious executables in intermediate directories along the path to achieve arbitrary code execution. The vulnerability is fixed in version 2.4.0.0570.

MitigationDeploy QVR Smart Client version 2.4.0.0570 or later to all affected client workstations. This is a client-side vulnerability affecting local authenticated administrators, so focus on endpoint patching and inventory of installations.

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 if QVR Smart Client is installed
    Open Windows Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product' in PowerShell to list installed software. Look for 'QVR Smart Client' in the program list.
    Affected if QVR Smart Client appears in the installed programs list
  2. Determine the installed version of QVR Smart Client
    In Programs and Features, click on QVR Smart Client to view the version, or check the program directory for a version file. Compare the version number against 2.4.0.0570.
    Affected if The installed version is 2.4.0 or higher but lower than 2.4.0.0570
  3. Inspect Windows services for QVR-related executables
    Open Services console (services.msc) or run 'sc qc' on any QVR-related services. Check the binary path for each service. Look for paths containing spaces that are not enclosed in quotation marks.
    Affected if A QVR service has a binary path with spaces that is not properly quoted (e.g., C:\Program Files\QVR Smart Client\bin\service.exe instead of "C:\Program Files\QVR Smart Client\bin\service.exe")
  4. Verify intermediate directory write access
    For any unquoted service path found, check if intermediate directories along the path are writable by local administrators. Useicacls or File Explorer security properties on each directory in the path.
    Affected if A local administrator can write to any intermediate directory in the unquoted service path

If QVR Smart Client version is between 2.4.0 and 2.4.0.0569 inclusive AND has an unquoted service path with writable intermediate directories, the system is vulnerable to CVE-2022-27592.
