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

Detection involves scanning for unauthorized or suspicious file uploads, especially web shells, on the affected WordPress site. Since the vulnerability allows arbitrary file uploads, look for recently uploaded files with unusual extensions or PHP files in upload directories. Commands to find suspicious files might include: `find /path/to/wordpress/wp-content/uploads/ -type f \( -name '*.php' -o -name '*.phtml' \) -exec ls -l {} \;` to list PHP files in upload directories. Additionally, monitoring web server logs for unusual POST requests to the upload endpoint or unexpected file upload activity can help detect exploitation attempts. Using malware scanning tools or hosting provider scanning services is also recommended. [1]
