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
The installers of LiveOn Meet Client for Windows (Downloader5Installer.exe and Downloader5InstallerForAdmin.exe) and the installers of Canon Network Camera Plugin (CanonNWCamPlugin.exe and CanonNWCamPluginForAdmin.exe) insecurely load Dynamic Link Libraries (DLLs). If a malicious DLL is placed at the same directory, the affected installer may load that DLL and execute its code with the privilege of the user invoking the installer.

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

The LiveOn Meet Client and Canon Network Camera Plugin Windows installers are vulnerable to DLL hijacking. The installers use insecure DLL search paths, allowing an attacker who can place a malicious DLL in the same directory as the installer to achieve code execution with the privileges of the user running the installer.

MitigationUsers should ensure the directory from which the installer is run is not writable by unprivileged users and contains no untrusted files. The vendor (Canon) must release patched installers that use secure DLL loading practices (e.g., safe DLL search mode, absolute 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. Locate affected installer files
    Search the file system for files matching these names: Canonnwcamplugin.exe, Canonnwcampluginforadmin.exe, Downloader5installer.exe, Downloader5installerforadmin.exe. Check typical installation directories, download folders, and temporary directories.
    Affected if Any of these four executables are found on the system with version 1.0.0.0
  2. Verify installer version
    Right-click each found executable, select Properties, and examine the File version field on the Details tab. Alternatively, run: Get-Item "path\to\executable" | Format-List *
    Affected if The File version shows exactly 1.0.0.0 for any of the affected installer executables
  3. Check directory writability
    Right-click the folder containing the installer, select Properties, then Security tab. Verify which users or groups have Write or Modify permissions. Alternatively, run: Get-Acl "path\to\directory" | Select-Object -ExpandProperty Access
    Affected if The directory containing the installer grants Write or Modify permissions to users other than the installer owner (such as Users, Authenticated Users, or Everyone)
  4. Inspect for suspicious DLLs
    List all DLL files in the same directory as the installer: Get-ChildItem "path\to\installer\directory" -Filter *.dll
    Affected if Unexpected or unrecognized DLL files exist in the directory alongside the installer, especially DLLs not belonging to the installer package

You are affected if any of the four installer executables with version 1.0.0.0 exist on your system and are stored in a directory writable by other users.

Mitigation

Users should ensure the directory from which the installer is run is not writable by unprivileged users and contains no untrusted files. The vendor (Canon) must release patched installers that use secure DLL loading practices (e.g., safe DLL search mode, absolute paths).
