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 traverse the directory on the affected webOS of LG Signage.

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 a directory traversal vulnerability in LG Signage webOS that allows remote attackers to access files outside the intended web root directory by manipulating file paths, potentially exposing sensitive system files or configuration data.

MitigationApply vendor-provided patches for LG Signage webOS and implement strict input validation on file path parameters to prevent directory traversal sequences.

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 webOS Signage version
    Access the web management interface or system settings panel to retrieve the installed webOS Signage version number
    Affected if The installed version matches 6.0.0 through 6.0.0-56 (or version 6.0.0 build 56 and below)
  2. Confirm web management interface is accessible
    Determine if the LG Signage web management interface is reachable over the network (HTTP/HTTPS on typical web ports)
    Affected if The web management interface is exposed and accessible from network segments where untrusted users could send requests
  3. Verify file request handling is enabled
    Check if the web server component that handles file path parameters in the Signage platform is active and processing user-supplied paths
    Affected if The file request handling functionality is enabled and accepts path parameters without additional validation layers

You are affected if your LG webOS Signage installation is version 6.0.0-56 or earlier and has the web management interface with file handling accessible to potential attackers.
