CVE-2015-20120Public exploitNetwork attack vector

Database disclosure via unsanitized SQL parameters

Published Mar 15, 2026 · Updated Mar 16, 2026

SQL injection in Next Click Ventures RealtyScript 4.0.2 allows remote attackers to extract database data through crafted parameters. The u_id GET parameter in /admin/users.php and agent[] POST parameter in /admin/mailer.php enter SQL queries without proper sanitization, enabling SLEEP-based timing inference. No authentication or user interaction is required, and the demonstrated consequence is database disclosure rather than service interruption.
