CVE-2025-9507 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System, specifically within the /report/visitor_info.php file. The vulnerability arises from improper sanitization or validation of the 'vid' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This can lead to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 score of 6.9 (medium severity) reflects the ease of exploitation (no privileges or user interaction required) but limited impact on confidentiality, integrity, and availability (all rated low to limited). No official patches have been published yet, and although no known exploits are reported 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 an apartment management system likely used by property management companies to handle visitor logs and related data. Given the nature of the system, the database may contain sensitive personal information about residents and visitors, making the confidentiality impact significant if exploited.

For European organizations, particularly property management firms and real estate companies using the itsourcecode Apartment Management System 1.0, this vulnerability poses a risk of unauthorized data access and potential data breaches involving personal visitor and resident information. Such breaches could lead to violations of the EU General Data Protection Regulation (GDPR), resulting in legal penalties and reputational damage. Additionally, attackers could manipulate or delete visitor records, impacting operational integrity and trustworthiness of the management system. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, especially if the system is exposed to the internet without adequate network protections. While the vulnerability does not directly enable system takeover, the exposure of sensitive data and potential for data tampering can disrupt business operations and customer trust.

1. Immediate mitigation should include restricting external access to the /report/visitor_info.php endpoint by implementing network-level controls such as firewalls or VPNs to limit access to trusted internal users only. 2. Apply input validation and parameterized queries or prepared statements in the application code to sanitize the 'vid' parameter and prevent SQL injection. Since no official patch is available, organizations should review and update the source code to fix the vulnerability or consider disabling the affected functionality temporarily. 3. Conduct thorough logging and monitoring of database queries and web server access to detect any suspicious activity related to the 'vid' parameter. 4. Perform regular security assessments and penetration testing focused on injection vulnerabilities. 5. If possible, upgrade to a newer, patched version of the software once released by the vendor. 6. Educate staff on the importance of securing web applications and maintaining up-to-date software versions. 7. Implement web application firewalls (WAFs) with specific rules to detect and block SQL injection attempts targeting this parameter.
