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/settings/upload 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

LG LED Assistant contains a path traversal vulnerability in the /api/settings/upload API endpoint that lacks proper validation of user-supplied file paths. An unauthenticated remote attacker can exploit this to write arbitrary files to the filesystem and achieve code execution in the context of the application user.

MitigationImplement strict whitelist-based path validation and sanitize user-supplied paths to prevent directory traversal sequences (../) before file operations. Restrict file upload locations to non-executable directories and apply proper file type validation.

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 version of LG LED Assistant
    Locate and inspect the application's version information through its UI, executable file properties, or any version documentation/file shipped with the installation
    Affected if the installed version is exactly 2.1.45
  2. Verify the application exposes the /api/settings/upload endpoint
    Attempt to access the endpoint via HTTP request (e.g., curl http://target:/api/settings/upload) and observe if the application responds or returns an error
    Affected if the endpoint responds and accepts requests, indicating the vulnerable feature is enabled
  3. Check network accessibility of the application
    Determine if the LG LED Assistant service is bound to a network interface accessible from untrusted sources or the internet
    Affected if the service is exposed to unauthenticated remote attackers (e.g., bound to 0.0.0.0 or publicly reachable IP)

A user is affected if LG LED Assistant version 2.1.45 is installed and the /api/settings/upload endpoint is accessible to unauthenticated attackers on the network.
