Detection Guidance

This vulnerability involves Local File Inclusion (LFI) in the WordPress WaveRide Theme versions 1.4 and below. Detection typically involves monitoring for suspicious HTTP requests attempting to include local files via the vulnerable PHP include/require statements.

You can detect exploitation attempts by inspecting web server logs for requests containing patterns like directory traversal sequences (e.g., ../) or attempts to include sensitive files such as /etc/passwd or configuration files.

Example commands to search for suspicious requests in Apache or Nginx logs:

• grep -i 'include' /var/log/apache2/access.log | grep '\.\./'
• grep -E '\.\./|etc/passwd|wp-config.php' /var/log/nginx/access.log

Additionally, using web application firewalls (WAF) or intrusion detection systems (IDS) with rules targeting LFI patterns can help detect and alert on exploitation attempts.
