CVE-2025-9510 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System, specifically within an unspecified function in the /branch/addbranch.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which allows an attacker to inject malicious SQL code. This injection can be performed remotely without requiring any authentication or user interaction, making exploitation relatively straightforward. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity. The vector metrics indicate that the attack can be launched over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and no authentication (AT:N). The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), suggesting that while the attacker can manipulate data, the scope and severity of damage are somewhat constrained. No public exploit is currently known to be actively used in the wild, but the exploit details have been publicly disclosed, increasing the risk of future exploitation. The vulnerability affects only version 1.0 of the software, and no patches or fixes have been linked or announced yet. Given that the affected software is an apartment management system, the vulnerability could expose sensitive tenant or property management data, or allow unauthorized modification of records, potentially disrupting operations or leading to data breaches.

For European organizations using the itsourcecode Apartment Management System 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of their data. Apartment management systems typically store personally identifiable information (PII) of tenants, payment records, lease agreements, and maintenance logs. Exploitation could lead to unauthorized disclosure of sensitive tenant data, financial fraud, or manipulation of property records. Although the CVSS score indicates limited impact, the ease of remote exploitation without authentication raises concerns, especially for organizations lacking robust network segmentation or web application firewalls. Disruption of apartment management operations could also affect service availability, tenant satisfaction, and regulatory compliance under GDPR, potentially resulting in legal and reputational consequences. The absence of known active exploits reduces immediate risk but does not eliminate the threat, especially as exploit code may emerge following public disclosure.

To mitigate this vulnerability, European organizations should first verify if they are running version 1.0 of the itsourcecode Apartment Management System. Immediate steps include restricting external network access to the affected web application, ideally limiting it to trusted internal networks or VPNs. Implementing a Web Application Firewall (WAF) with SQL injection detection and prevention rules can help block exploitation attempts. Input validation and parameterized queries should be enforced within the application code; if source code access is available, developers should sanitize the 'ID' parameter in /branch/addbranch.php to prevent injection. Organizations should monitor web server and application logs for suspicious activity targeting the 'ID' parameter. Until an official patch is released, consider deploying virtual patching via WAF or IPS solutions. Additionally, conduct a thorough audit of tenant and financial data for signs of unauthorized access or modification. Planning for an upgrade or migration to a patched or alternative apartment management system is advisable to eliminate the vulnerability permanently.
