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
A local attacker can gain administrative privileges by inserting an executable file in the path of the affected product.

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

The vulnerability allows a local attacker to achieve privilege escalation by placing a malicious executable in a location where the affected product will inadvertently execute it. This indicates insecure path resolution where the application uses relative paths or does not properly validate the full path to executables it calls, allowing PATH manipulation or binary planting.

MitigationImplement absolute path validation for all executable calls and ensure the application uses full, validated paths rather than relying on the system PATH environment variable or relative paths.

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 installed Wut product and version
    Check Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'Wut Com Port Redirector' or 'Wut Opc Server', or check the application's About/Help dialog for the version number
    Affected if The installed version is at or below 3.93 for Legacy, 4.42 for Plug & Play, or 4.88 for Opc Server
  2. Locate the application installation directory
    Find the installation path by right-clicking the application shortcut and selecting 'Open file location', or check the registry Uninstall key for the InstallLocation value
    Affected if The application is installed in a directory writable by standard users (common in C:\Program Files\ or C:\Program Files (x86)\)
  3. Identify executable calls made by the application
    Examine configuration files in the installation directory (look for .ini, .cfg, .xml, or .conf files) and check for entries that specify executable paths or commands, noting whether they use absolute or relative paths
    Affected if Configuration files contain relative paths or no path prefixes for executables (e.g., 'mytool.exe' instead of 'C:\Program Files\Wut\mytool.exe')
  4. Check service or scheduled task configurations
    Open Services.msc to find Wut-related services, right-click and select Properties, then check the 'Path to executable' field. Also check Task Scheduler for any Wut-related tasks under Task Scheduler Library
    Affected if The service executable path or any called programs in service properties use relative paths or depend on PATH environment variable

You are affected if any Wut product (Com Port Redirector Legacy <=3.93, Plug & Play <=4.42, or Opc Server <=4.88) is installed and the application or its services execute programs using relative or PATH-dependent paths that could be exploited through binary planting.
