Detection Guidance

To detect this SQL injection vulnerability, monitor network traffic for suspicious POST requests to the CMS search endpoint. Look for requests containing the 'content' parameter with SQL-like payloads such as ' OR 1=1 -- or 'notfound%' AND 1=2 AND 'x'='y'. Use tools like Wireshark or tcpdump to capture traffic. Check server logs for unusual database queries or errors.
