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

Reflected XSS vulnerability in LG Electronics SuperSign CMS allows attackers to inject malicious scripts through unsanitized user input that gets reflected back in web pages. The vulnerability exists in versions from 4.1.3 before 4.3.1.

MitigationUpgrade SuperSign CMS to version 4.3.1 or later which contains the security patch. As an interim measure, implement input validation and output encoding on all user-supplied parameters.

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. Check SuperSign CMS version in admin interface
    Log into the SuperSign CMS admin panel and navigate to System Settings or About page to find the software version number
    Affected if The displayed version is 4.1.3 or any version from 4.1.3 up to but not including 4.3.1
  2. Check version via system information
    If direct admin access is unavailable, check installation documentation or system files for version information, or query the system package manager if applicable
    Affected if Version cannot be confirmed as 4.3.1 or later
  3. Determine if web interface is accessible
    Verify whether the SuperSign CMS web management interface is reachable over the network (HTTP/HTTPS)
    Affected if The web interface is exposed and the version cannot be confirmed as 4.3.1 or later
  4. Identify reflected input parameters
    Access the web login page or common input forms and inspect the HTTP response when submitting test input in parameters (such as search fields or login username) to observe if input is reflected in the response without encoding
    Affected if User-supplied input is reflected in the HTML response without proper sanitization and version is in the affected range

You are affected if SuperSign CMS version is 4.1.3 or later but earlier than 4.3.1 and the web interface is accessible for users to inject malicious scripts through unsanitized parameters.

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 which contains the security patch. As an interim measure, implement input validation and output encoding on all user-supplied parameters.

Recommended fix High confidence

4.3.1 or later

  1. 1. Identify the current installed version of SuperSign CMS
  2. 2. Create a complete backup of the SuperSign CMS database and configuration files
  3. 3. Review LG Electronics SuperSign CMS upgrade documentation for version 4.3.1
  4. 4. Upgrade SuperSign CMS to version 4.3.1 or later
  5. 5. After upgrade, verify the new version is running (e.g., check About or version info in the CMS interface)
  6. 6. Confirm the upgrade was successful by logging into the CMS and testing functionality
