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
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in LG Electronics SuperSign CMS allows Reflected XSS. This issue affects SuperSign CMS: from 4.1.3 before < 4.3.1.

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

This is a reflected Cross-Site Scripting (XSS) vulnerability in LG Electronics SuperSign CMS versions 4.1.3 through before 4.3.1. The vulnerability allows attackers to inject malicious JavaScript code through unsanitized user input that gets reflected in web pages generated by the CMS.

MitigationUpgrade SuperSign CMS to version 4.3.1 or later. Additionally, implement proper input validation and output encoding for all user-supplied data rendered in web pages, and consider deploying a Content Security Policy (CSP) header as a defense-in-depth measure.

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 the SuperSign CMS version
    Log into the SuperSign CMS web interface and navigate to the About or System Information page typically found in Settings or Admin menu. Alternatively, check the installation directory for version.txt or a config file that lists the CMS version.
    Affected if The displayed version is 4.1.3, 4.1.4, 4.1.5, 4.2.0, 4.2.1, 4.2.2, 4.2.3, 4.2.4, 4.2.5, 4.2.6, 4.2.7, 4.2.8, 4.2.9, 4.2.10, or any version 4.3.0 and below before 4.3.1.
  2. Verify the vulnerable version range
    Compare the identified version number against the affected range: version >= 4.1.3 AND version < 4.3.1. If the version is 4.3.1 or later, the system is not affected by this specific CVE.
    Affected if The installed version meets both conditions: it is 4.1.3 or higher, AND it is below 4.3.1.
  3. Confirm SuperSign CMS is internet-facing or accessible to untrusted users
    Review network exposure settings, firewall rules, or reverse proxy configurations to determine if the SuperSign CMS web interface can be accessed by users outside the trusted internal network.
    Affected if The CMS web interface is exposed to the internet or accessible to untrusted/browsing users without proper network segmentation.
  4. Identify user input reflection points
    Review the SuperSign CMS web application for URL parameters or form inputs that may reflect data back into rendered HTML pages without sanitization. Common areas include search fields, login error messages, navigation parameters, or URL-based values.
    Affected if The application contains any web page that reflects URL parameters, query strings, or form input values directly into the page output without encoding or validation.

You are affected if the SuperSign CMS version is 4.1.3 or higher but below 4.3.1, and the web interface is accessible to users who could inject malicious script content through unsanitized input fields.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 4.3.1 or later
Fixed in 4.3.1
Interim mitigation

Upgrade SuperSign CMS to version 4.3.1 or later. Additionally, implement proper input validation and output encoding for all user-supplied data rendered in web pages, and consider deploying a Content Security Policy (CSP) header as a defense-in-depth measure.

Recommended fix Moderate confidence

4.3.1 or later

  1. Identify the current version of LG SuperSign CMS installed
  2. If version is >= 4.1.3 and < 4.3.1, plan upgrade to version 4.3.1 or later
  3. Obtain the upgrade package from official LG Electronics channels (lgsecurity.lge.com)
  4. Backup current CMS configuration and database before upgrading
  5. Apply the upgrade following LG's official upgrade procedures
  6. Verify the upgrade was successful and the new version is running
