What is CVE-2015-20121?

RealtyScript version 4.0.2 is susceptible to SQL injection vulnerabilities that permit unauthenticated attackers to execute arbitrary SQL commands. Specifically, the vulnerabilities are exploited through the 'u_id' GET parameter in /admin/users.php and the 'agent[]' POST parameter in /admin/mailer.php. Attackers may leverage time-based blind SQL injection techniques to retrieve sensitive information from the database or trigger denial of service conditions by utilizing sleep-based payloads. This flaw poses significant risks to database integrity and data confidentiality.
