Detection Guidance

This vulnerability is an unauthenticated Local File Inclusion (LFI) flaw in the WordPress Hitek Theme version 1.8.3 or lower. Detection typically involves monitoring for suspicious HTTP requests attempting to include local files.

You can detect potential exploitation attempts by searching your web server logs for requests containing typical LFI attack patterns such as directory traversal sequences (e.g., ../) or attempts to include sensitive files.

• Use grep or similar tools to search access logs for suspicious patterns, for example: grep -E "(\.{2}/|etc/passwd|boot.ini)" /var/log/apache2/access.log
• Monitor for unusual HTTP requests targeting the theme's files or parameters that may be vulnerable to LFI.

Additionally, applying the mitigation rule provided by Patchstack can help block attack attempts until the theme is updated.
