CVE-2025-9597 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System, specifically affecting an unknown function within the file /o_dashboard/rented_all_info.php. The vulnerability arises from improper sanitization or validation of the 'uid' parameter, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables an attacker to manipulate backend database queries, potentially leading to unauthorized access, data leakage, data modification, or even complete compromise of the database. The vulnerability is remotely exploitable over the network with low attack complexity and no privileges or user interaction needed, as indicated by the CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N). Although the CVSS score is 6.9 (medium severity), the impact on confidentiality, integrity, and availability is limited but still significant, as the vulnerability could allow partial data exposure or modification. No official patches or mitigations have been published yet, and while no known exploits are currently observed in the wild, a public exploit is available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is a niche apartment management system likely used by property management companies or real estate firms to handle tenant and rental information.

For European organizations using the itsourcecode Apartment Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive tenant and rental data, which could include personally identifiable information (PII), payment details, and lease agreements. Exploitation could lead to data breaches, violating GDPR and other privacy regulations, resulting in legal penalties and reputational damage. Additionally, attackers could alter rental records or disrupt system availability, impacting business operations and tenant trust. Given the remote exploitability and lack of authentication requirements, attackers could target these systems from anywhere, increasing the threat surface. Organizations managing large portfolios of apartments or housing complexes in Europe are particularly at risk, as the compromise of such systems could affect thousands of tenants. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional chained exploits. However, the presence of a public exploit increases the urgency for mitigation.

1. Immediate mitigation should involve restricting external access to the affected /o_dashboard/rented_all_info.php endpoint via network-level controls such as firewalls or VPNs, limiting exposure to trusted internal networks only. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'uid' parameter. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize the 'uid' parameter and all other user inputs in the application. 4. If possible, upgrade to a patched version once available or contact the vendor for security updates. 5. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 6. Perform regular security assessments and penetration testing focusing on SQL injection vectors. 7. Educate IT and security teams about this vulnerability and ensure incident response plans include steps for SQL injection incidents. 8. As a longer-term measure, consider migrating to more secure and actively maintained apartment management solutions with robust security practices.
