Detection Guidance

This vulnerability can be detected by testing the 'remark' parameter in the URL /apartment-visitor/action-visitor.php for SQL injection weaknesses.

A common method is to use time-based blind SQL injection payloads that cause delayed responses if the injection is successful.

For example, you can use curl or similar tools to send requests with SQL injection payloads in the 'remark' parameter and observe response delays.

• curl "http://target/apartment-visitor/action-visitor.php?editid=20&remark=' OR IF(SLEEP(5),1,0)-- -"
• Use automated SQL injection detection tools like sqlmap targeting the 'remark' parameter to confirm the vulnerability.
