CVE-2025-9417 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System, specifically within the /employee/addemployee.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, allowing an attacker to inject malicious SQL code. This injection flaw enables remote attackers to manipulate backend database queries without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability impacts the confidentiality, integrity, and availability of the database by potentially allowing unauthorized data access, modification, or deletion. Although the CVSS score is medium (5.3), the exploit has been publicly disclosed, increasing the risk of exploitation. The vulnerability requires low privileges (PR:L), meaning an attacker needs some level of authenticated access but no user interaction is needed. The scope is limited to the Apartment Management System version 1.0, and no patches have been published yet. The lack of known exploits in the wild suggests limited active exploitation currently, but public availability of the exploit code raises the likelihood of future attacks.

For European organizations using the itsourcecode Apartment Management System 1.0, this vulnerability could lead to significant data breaches involving sensitive tenant and employee information. Unauthorized access to the database could expose personal data, violating GDPR regulations and resulting in legal and financial penalties. Data integrity could be compromised, affecting operational reliability and trustworthiness of the management system. Availability could also be impacted if attackers execute destructive SQL commands, potentially disrupting apartment management services. Given the medium severity and the requirement for some level of authenticated access, the threat is more pronounced for insiders or attackers who have obtained credentials. The public availability of exploit code increases the urgency for European organizations to assess and mitigate this risk promptly to avoid reputational damage and regulatory consequences.

European organizations should implement the following specific mitigations: 1) Immediately audit and restrict access controls to the Apartment Management System, ensuring only trusted personnel have authenticated access. 2) Apply input validation and parameterized queries or prepared statements in the /employee/addemployee.php script to prevent SQL injection. 3) If vendor patches are unavailable, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable parameter. 4) Conduct thorough code reviews and penetration testing focusing on SQL injection vectors within the system. 5) Monitor logs for suspicious database query patterns or unauthorized access attempts. 6) Plan for an upgrade or replacement of the vulnerable system version as soon as a patch or secure version becomes available. 7) Ensure compliance with GDPR by encrypting sensitive data at rest and in transit to minimize exposure in case of a breach.
