CVE-2025-5580 is a SQL Injection vulnerability identified in version 1.0 of the CodeAstro Real Estate Management System, specifically affecting the /login.php file. The vulnerability arises from improper sanitization or validation of the 'email' parameter, allowing an attacker to inject malicious SQL code remotely without any authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or even complete compromise of the database. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no confirmed exploits are currently observed in the wild. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with an attack vector of network (remote), low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. The vulnerability does not require authentication and can be exploited remotely, making it a significant risk for affected deployments.

For European organizations using CodeAstro Real Estate Management System 1.0, this vulnerability poses a substantial risk to the confidentiality and integrity of sensitive real estate data, including client information, transaction records, and login credentials. Successful exploitation could lead to unauthorized data disclosure, data tampering, or disruption of service availability, undermining trust and potentially causing regulatory compliance issues under GDPR due to exposure of personal data. Real estate firms, property management companies, and related service providers relying on this software could face operational disruptions and reputational damage. Given the critical nature of real estate data, attackers might also leverage this vulnerability for further lateral movement within networks or to conduct fraud. The public disclosure of the vulnerability increases the urgency for European organizations to assess and remediate the risk promptly.

Organizations should immediately audit their use of CodeAstro Real Estate Management System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'email' parameter in /login.php. Employ input validation and parameterized queries or prepared statements in the application code to prevent injection. Conduct thorough code reviews and penetration testing focused on SQL injection vectors. Additionally, monitor logs for suspicious activity related to login attempts and unusual database queries. Segmentation of the database and limiting database user privileges can reduce the impact of a successful injection. Finally, ensure regular backups are maintained to enable recovery in case of data corruption or loss.
