NVD · unedited
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in themeStek Xinterio xinterio allows PHP Local File Inclusion.This issue affects Xinterio: from n/a through <= 4.2.

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

The Xinterio WordPress theme (versions up to 4.2) contains a PHP Local File Inclusion vulnerability where improper control of filenames in include/require statements allows attackers to manipulate path parameters and execute arbitrary PHP code by including malicious local files.

MitigationUpdate Xinterio theme to the latest patched version immediately. If no patch is available, disable the theme and replace with a secure alternative, or implement input validation and web application firewall rules as temporary mitigations.

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. Locate Xinterio theme installation
    Check the WordPress themes directory (wp-content/themes/) for the xinterio folder. If using a file manager or CLI: ls -la /path/to/wordpress/wp-content/themes/ | grep -i xinterio
    Affected if The xinterio folder exists in the themes directory
  2. Identify installed Xinterio version
    Open the theme's style.css file located at wp-content/themes/xinterio/style.css and look for the 'Version:' header in the CSS comment block at the top
    Affected if Version is 4.2 or below, or if no version is declared treat as potentially affected
  3. Find vulnerable include/require statements
    Search the theme's PHP files for include, require, include_once, or require_once statements that use variables in the path (e.g., include($_GET['param'])). Search command: grep -r '\$.*include\|\$.*require' wp-content/themes/xinterio/
    Affected if Any include/require statement uses a variable without sanitization, particularly path-related parameters
  4. Check for path traversal parameters
    Review PHP files that handle template inclusion or routing (commonly functions.php, header.php, or custom template loaders). Look for $_GET, $_POST, or $_REQUEST variables used in file path operations
    Affected if URL parameters can be manipulated to traverse directories (e.g., ../../) or inject file paths
  5. Look for signs of exploitation
    Check web server access logs for unusual requests containing ../ sequences or alternative file extensions (e.g., ?page=../../../../etc/passwd). Also examine theme directories for newly created suspicious PHP files
    Affected if Log entries show path traversal attempts or unexpected PHP files appear in the theme folder

You are affected if Xinterio theme version 4.2 or lower is installed and the vulnerable include/require code paths using user input are accessible on your WordPress site.
