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
This vulnerability allows remote attackers to execute arbitrary code on affected installations of LG LED Assistant. Authentication is not required to exploit this vulnerability. The specific flaw exists within the /api/installation/setThumbnailRc endpoint. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of the current user.

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

A path traversal vulnerability in LG LED Assistant's /api/installation/setThumbnailRc endpoint allows unauthenticated remote attackers to manipulate user-supplied file paths and achieve arbitrary code execution in the context of the current user. The lack of input validation on the path parameter enables attackers to write malicious files to arbitrary locations.

MitigationImplement strict path validation and sanitization on the /api/installation/setThumbnailRc endpoint to ensure user-supplied paths are restricted to allowed directories and do not contain traversal sequences (..). Apply principle of least privilege to the application process.

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. Verify LG LED Assistant installation
    Check if LG LED Assistant is installed on the system. Look for the application in Program Files (Windows) or /Applications (macOS). On Windows, check registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for LG LED Assistant entry.
    Affected if LG LED Assistant application is found on the system
  2. Check installed version
    Locate the version information for LG LED Assistant. Check the application executable properties (right-click > Properties > Details), or the uninstall registry entry, or the version info in the application folder. Compare against the affected version 2.1.45.
    Affected if Installed version is exactly 2.1.45
  3. Identify network exposure
    Determine if LG LED Assistant is running as a network service or exposing an HTTP server. Check for processes listening on common ports (typically 8080, 8000, 3000) when the application is active. Review firewall rules for any inbound rules allowing traffic to LG LED Assistant service.
    Affected if The application exposes an HTTP server accessible over the network on the vulnerable endpoint path
  4. Test vulnerable endpoint accessibility
    If the application runs a local web server, send a crafted request to /api/installation/setThumbnailRc endpoint with a path parameter containing traversal sequences (e.g., ../../../../) to observe if the application accepts and processes such input.
    Affected if The /api/installation/setThumbnailRc endpoint is reachable and accepts path parameters without validation

The environment is affected if LG LED Assistant version 2.1.45 is installed and the /api/installation/setThumbnailRc endpoint is exposed and accepts unsanitized path traversal input.
