CVE-2025-9418 is a SQL Injection vulnerability identified in the itsourcecode Apartment Management System version 1.0. The vulnerability exists in an unspecified function within the /owner/addowner.php file, where manipulation of the 'ID' parameter allows an attacker to inject malicious SQL code. This injection flaw enables remote exploitation without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, as attackers can potentially extract sensitive data, modify database contents, or disrupt service operations. The CVSS score of 6.9 (medium severity) reflects a moderate risk, primarily due to the lack of authentication requirements and ease of exploitation, but with limited scope and impact compared to more critical vulnerabilities. No official patches or fixes have been disclosed yet, and while public exploit code has been published, there are no confirmed reports of active exploitation in the wild. The vulnerability affects only version 1.0 of the product, which is a niche apartment management software solution used to handle tenant and property data.

For European organizations using the itsourcecode Apartment Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of tenant and property management data. Exploitation could lead to unauthorized disclosure of personally identifiable information (PII), financial details, and lease agreements, potentially violating GDPR requirements and resulting in regulatory penalties. Additionally, attackers could alter or delete critical records, disrupting property management operations and causing financial and reputational damage. The remote and unauthenticated nature of the attack increases the risk of widespread exploitation if the system is exposed to the internet without adequate protections. Given the sensitive nature of housing and tenant data in Europe, this vulnerability could impact property management companies, housing associations, and real estate firms relying on this software, especially those with limited cybersecurity resources.

Organizations should immediately conduct an inventory to identify any deployments of itsourcecode Apartment Management System version 1.0. Since no official patch is currently available, mitigating controls include: 1) Implementing web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the /owner/addowner.php endpoint and the 'ID' parameter. 2) Restricting external access to the application by placing it behind VPNs or internal networks, minimizing exposure to the internet. 3) Employing input validation and parameterized queries if source code access and modification is possible, to sanitize user inputs and prevent injection. 4) Monitoring logs for suspicious database queries or repeated failed attempts to exploit the injection point. 5) Planning for an upgrade or migration to a patched or alternative apartment management solution once available. 6) Conducting regular backups of the database to enable recovery in case of data tampering or loss.
