CVE-2025-5611 is a SQL Injection vulnerability identified in version 1.0 of the CodeAstro Real Estate Management System, specifically within the /submitpropertyupdate.php file. The vulnerability arises due to improper sanitization or validation of the 'ID' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild to date. The CVSS 4.0 score is 5.3 (medium severity), reflecting that the attack vector is network-based with low attack complexity and no privileges or user interaction needed, but with limited impact on confidentiality, integrity, and availability. The vulnerability could potentially allow attackers to read, modify, or delete sensitive data related to property listings or user information managed by the system, undermining data integrity and confidentiality. Since the affected product is a real estate management system, the impact could extend to business operations, client trust, and regulatory compliance, especially concerning personal data protection.

For European organizations using the CodeAstro Real Estate Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive real estate and client data. Exploitation could lead to unauthorized data disclosure, data tampering, or disruption of property management operations. Given the strict data protection regulations in Europe, including GDPR, any data breach could result in substantial legal and financial penalties. Additionally, compromised systems could be leveraged for further attacks within the network, potentially affecting other critical business functions. The real estate sector often handles large volumes of personal and financial data, making such vulnerabilities particularly impactful. Organizations may face reputational damage, loss of client trust, and operational downtime if exploited. The medium CVSS score suggests a moderate but non-negligible threat that requires timely attention.

To mitigate this vulnerability, European organizations should immediately apply any available patches or updates from CodeAstro; if none are available, they should implement compensating controls such as input validation and parameterized queries to prevent SQL injection. Conduct thorough code reviews focusing on the /submitpropertyupdate.php file and the handling of the 'ID' parameter. Employ Web Application Firewalls (WAFs) configured to detect and block SQL injection attempts targeting this endpoint. Regularly audit database access logs for suspicious queries or anomalies. Limit database user privileges to the minimum necessary to reduce the impact of potential exploitation. Additionally, organizations should monitor public vulnerability disclosures and threat intelligence feeds for any emerging exploit activity related to CVE-2025-5611. Finally, ensure that incident response plans include procedures for SQL injection attacks to enable rapid containment and recovery.
