CVE-2015-20121Public exploitNetwork attack vector

Database data extraction via unsanitized request parameters

Published Mar 15, 2026 · Updated Mar 15, 2026

SQL injection in Next Click Ventures RealtyScript 4.0.2 allows remote attackers to read database data via crafted HTTP requests. The /admin/users.php and /admin/mailer.php handlers pass the u_id GET value and agent[] POST value into SQL queries without sanitization. Network access to an exposed instance is sufficient; time-based SLEEP payloads can extract database values or delay query processing.
