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 Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Magentech SW Core allows PHP Local File Inclusion. This issue affects SW Core: from n/a through 1.7.18.

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 Local File Inclusion (LFI) vulnerability in Magentech SW Core where improper control of filenames in PHP include/require statements allows attackers to include arbitrary local files. The vulnerability has a CVSS 7.5 (HIGH) rating, indicating significant risk of information disclosure or potentially remote code execution depending on server configuration.

MitigationImplement strict input validation and whitelist-based filtering on all file inclusion parameters to ensure only authorized files can be included. Consider using realpath() validation and disabling allow_url_include if not needed.

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 Magentech SW Core installation
    Locate the main application directory and confirm the presence of Magentech SW Core by checking for core configuration files, readme files, or the main entry point script (commonly index.php or a core loader file)
    Affected if The application directory contains Magentech SW Core files
  2. Check installed version
    Open the version file or check the main configuration file for the version number. Common locations include a version.php, config.php, or a readme.txt file in the root directory
    Affected if The installed version is 1.7.18 or any version lower than 1.7.18
  3. Identify file inclusion code patterns
    Search the codebase for include() and require() statements that use variables or parameters without validation. Look for patterns like 'include($', 'require($', 'include($_', 'require($_' in PHP files within the application
    Affected if The code contains include/require statements that directly use unvalidated user input in the filename parameter
  4. Inspect the vulnerable module
    Examine PHP files in the include/ or modules/ directories for filename parameters that accept user-supplied input and are passed directly to include/require without sanitization
    Affected if File inclusion functions receive raw user input without validation or allowlisting
  5. Review web server access logs
    Check Apache/nginx access logs for requests containing path traversal sequences (../) or direct file paths in parameters that may indicate LFI exploitation attempts
    Affected if Logs show suspicious requests with path traversal or direct file path parameters being passed to the application

You are affected if Magentech SW Core version 1.7.18 or lower is installed AND the application contains include/require statements using unvalidated user-supplied input for filenames.
