How can this vulnerability be detected on my network or system? Can you suggest some commands?

This vulnerability allows an attacker with at least Contributor or Developer privileges to include local files from the target website and display their contents. Detection involves checking if the WordPress OrganicFood Theme version is up to and including 3.6.4, as these versions are vulnerable.

Since the vulnerability is a Local File Inclusion (LFI), one way to detect it is by attempting to include local files via crafted HTTP requests targeting the theme's include/require statements. Monitoring web server logs for suspicious requests attempting to include files such as /etc/passwd or wp-config.php can help identify exploitation attempts.

No specific commands are provided in the resources, but general detection commands could include using curl or wget to test for LFI, for example:

• curl -v "http://yourwebsite.com/path_to_vulnerable_script?file=../../../../etc/passwd"
• grep -i 'include' /path/to/wordpress/wp-content/themes/organicfood/* -r

Additionally, scanning the theme version can be done by checking the theme's style.css or using WordPress CLI commands to identify the installed theme version.
