CVE-2025-9598 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System, specifically within the /setting/year_setup.php file. The vulnerability arises due to improper sanitization or validation of the 'txtXYear' parameter, which is susceptible to malicious input manipulation. An attacker can remotely exploit this flaw by injecting crafted SQL commands through the vulnerable parameter, potentially allowing unauthorized access to the backend database. This could lead to unauthorized data retrieval, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability requires no authentication or user interaction, making it accessible to any remote attacker. The CVSS 4.0 score of 6.9 (medium severity) reflects the ease of exploitation (network attack vector, low attack complexity) and the partial impact on confidentiality, integrity, and availability. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of imminent attacks. The vulnerability affects only version 1.0 of the product, which is an apartment management system likely used by property management companies to handle tenant data, billing, and other administrative functions.

For European organizations using the itsourcecode Apartment Management System 1.0, this vulnerability poses a significant risk to sensitive tenant and financial data. Successful exploitation could lead to unauthorized disclosure of personal information, financial records, or operational data, potentially violating GDPR and other data protection regulations. Data integrity could be compromised, leading to incorrect billing or tenant records, which may disrupt business operations and damage organizational reputation. Availability impacts could result from database corruption or denial of service caused by malicious SQL commands. Given the remote exploitability without authentication, attackers could target multiple organizations indiscriminately, increasing the threat landscape. 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 exposure of apartment management systems, which often contain personally identifiable information (PII), makes this vulnerability particularly concerning for European entities focused on data privacy and regulatory compliance.

Organizations should immediately assess their deployment of the itsourcecode Apartment Management System and identify any instances running version 1.0. Since no official patch links are provided, users should contact the vendor for a security update or patch addressing CVE-2025-9598. In the interim, applying web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'txtXYear' parameter can reduce risk. Input validation and sanitization should be implemented or enhanced to reject malicious input at the application level. Network segmentation and access controls should limit exposure of the management system to trusted internal networks only. Regular database backups and monitoring for unusual query activity can help detect and recover from exploitation attempts. Additionally, organizations should review logs for any signs of attempted or successful exploitation and prepare incident response plans accordingly. If feasible, upgrading to a newer, unaffected version of the software is recommended once available.
