NVD · unedited
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Ogun Labs Lenxel Core for Lenxel(LNX) LMS lenxel-core allows PHP Local File Inclusion.This issue affects Lenxel Core for Lenxel(LNX) LMS: from n/a through <= 1.3.9.

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

Path Traversal vulnerability in Lenxel Core for Lenxel(LNX) LMS allows remote attackers to perform PHP Local File Inclusion (LFI) by manipulating file path inputs with '..' sequences or absolute paths, potentially exposing sensitive system files, configuration data, or enabling arbitrary code execution.

MitigationImplement strict input validation and path sanitization to restrict file inclusions to allowed directories only; upgrade to a patched version beyond 1.3.9 when available from the vendor.

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 if Lenxel (LNX) LMS is installed
    Search the web server for Lenxel-related directories, files, or components. Common paths include /wp-content/plugins/lenxel* or similar LMS-related directories. Check for 'lenxel', 'lms', or 'lnx' strings in the codebase.
    Affected if Lenxel LMS or its Core component is present on the server
  2. Determine the installed Lenxel Core version
    Locate version files within the Lenxel installation, such as readme.txt, plugin header comments, composer.json, or a version.php file within the lenxel core directories. Inspect the main plugin file for 'Version:' metadata.
    Affected if The installed version is 1.3.9 or lower (versions prior to the patch)
  3. Locate file inclusion code paths
    Search the codebase for PHP file inclusion functions that use user-controlled input: include(), require(), include_once(), require_once(). Look for parameters that accept file paths and could be manipulated with '..' or absolute paths.
    Affected if File inclusion code exists that references user-supplied input without proper sanitization
  4. Identify accessible endpoints leveraging file inclusion
    Review URL routing and application entry points. Identify which HTTP parameters accept file/path values and are passed to inclusion functions. Test if these parameters are reachable without authentication.
    Affected if Endpoints exist that pass user-supplied path parameters to PHP inclusion functions without validation
  5. Test for path traversal vulnerability
    Send HTTP requests with '..' sequences or absolute paths (e.g., ../../../../etc/passwd or /etc/passwd) to identified endpoints. Observe if file contents are returned or if the application attempts to include the specified file.
    Affected if The application returns file contents or includes files outside the intended directory when '..' or absolute paths are supplied

A user is affected if Lenxel Core for LNX LMS is installed with version 1.3.9 or lower AND the file inclusion functionality is accessible to attackers.
