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

[{'type': 'paragraph', 'content': 'The vulnerability in the ReviewX WordPress plugin allows unauthenticated attackers to access sensitive information via the allReminderSettings function. Detection would involve monitoring for unauthorized access attempts to this function or unusual API calls related to reminder settings or data export endpoints.'}, {'type': 'paragraph', 'content': 'Since the plugin exposes endpoints that allow exporting sensitive data (e.g., via the syncedData method that serves JSONL files), you can detect exploitation attempts by checking web server logs for HTTP requests targeting ReviewX REST API endpoints such as those related to reminder settings or data export.'}, {'type': 'paragraph', 'content': 'Suggested commands to detect suspicious activity include searching web server logs for requests to ReviewX REST API endpoints:'}, {'type': 'list_item', 'content': "grep -i 'reviewx' /var/log/apache2/access.log | grep -E 'allReminderSettings|syncedData|dataSync'"}, {'type': 'list_item', 'content': "grep -i 'reviewx' /var/log/nginx/access.log | grep -E 'allReminderSettings|syncedData|dataSync'"}, {'type': 'paragraph', 'content': 'Additionally, monitoring for unusual HTTP GET or POST requests to these endpoints from unauthenticated IP addresses may help detect exploitation attempts.'}] [1, 4]
