Summary
Next Click Ventures RealtyScript 4.0.2 contains SQL injection vulnerabilities that allow unauthenticated attackers to manipulate database queries by injecting arbitrary SQL code through the GET parameter 'u_id' in /admin/users.php and the POST parameter 'agent[]' in /admin/mailer.php. Attackers can exploit time-based blind SQL injection techniques to extract sensitive database information or cause denial of service through sleep-based payloads.
