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

This vulnerability involves missing authorization checks in the Commerce Coinbase For WooCommerce plugin, allowing unauthenticated users to perform privileged actions. Detection typically involves monitoring for unauthorized access attempts or unusual activity targeting the plugin's endpoints.

Since the vulnerability is related to broken access control in a WordPress plugin, you can detect exploitation attempts by reviewing web server logs for suspicious requests to the plugin's URLs or by using web application firewall (WAF) rules to identify unauthorized access patterns.

No specific detection commands are provided in the available resources. However, general commands to check for suspicious HTTP requests in web server logs might include:

• Using grep to search for requests to the plugin path in Apache or Nginx logs: grep -i 'commerce-coinbase-for-woocommerce' /var/log/apache2/access.log
• Using grep to find HTTP requests with suspicious parameters or methods: grep -E 'POST|GET' /var/log/apache2/access.log | grep 'commerce-coinbase-for-woocommerce'

Additionally, monitoring for unexpected privilege escalations or changes in user roles within WordPress could help identify exploitation attempts.
