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
Unauthenticated Local File Inclusion in Gunslinger <= 1.7 versions.

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

Unauthenticated Local File Inclusion (LFI) vulnerability in Gunslinger CMS versions 1.7 and below allows remote attackers to read sensitive files on the server without any authentication credentials.

MitigationUpdate Gunslinger to a version newer than 1.7. If no patched version is available, implement strict input validation on file inclusion parameters and restrict filesystem access controls.

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 Gunslinger CMS installation
    Look for the Gunslinger CMS application on your server. Check web directories, content management system folders, or application listings for a Gunslinger installation.
    Affected if Gunslinger CMS is present on the server
  2. Determine installed version
    Locate the version file or metadata in the Gunslinger installation. This is typically found in a version.php, composer.json, or similar configuration file within the application root directory.
    Affected if The installed version is 1.7 or lower
  3. Verify unauthenticated access is possible
    Confirm that the Gunslinger CMS allows unauthenticated access to its file inclusion functionality. Try accessing common CMS endpoints without providing credentials.
    Affected if File inclusion endpoints are accessible without authentication
  4. Check for LFI-accessible parameters
    Examine the application's URL parameters and request handling to identify any file inclusion or file path parameters that could be manipulated.
    Affected if The application accepts file path parameters that can be manipulated to read arbitrary files

Your environment is affected if Gunslinger CMS version 1.7 or lower is installed and the file inclusion functionality is accessible without authentication, allowing unauthenticated attackers to read arbitrary files on the server.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.
