  • →Detect error-based SQLi exploitation attempt: look for HTTP GET requests to /student.php with the 'id' parameter containing EXTRACTVALUE and CONCAT payloads; a 200 response containing 'XPATH syntax error' in the body confirms exploitation. ↗
  • →Detect time-based blind SQLi exploitation attempt: look for HTTP GET requests to /student.php with the 'id' parameter containing SLEEP(7); a response duration >= 7 seconds with HTTP 302 redirecting to login.php indicates successful injection. ↗
  • →The vulnerability is unauthenticated (PR:N) and exploitable via the 'id' GET parameter on /student.php with the 'action=delete' operation; no session or login is required to trigger the injection. ↗
  • ·The time-based detection threshold is set to 7 seconds (SLEEP(7)); on high-latency or heavily loaded servers, this threshold may produce false positives or false negatives and should be tuned to baseline response times. ↗
  • ·The time-based SQLi probe expects an HTTP 302 redirect to login.php, indicating the application redirects unauthenticated users after the injected query executes; detection logic must account for this redirect behaviour rather than a direct 200 response. ↗
