CVE-2025-9593 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System, specifically within an unknown function in the /report/unit_status_info.php file. The vulnerability arises from improper sanitization or validation of the 'usid' parameter, which is susceptible to malicious input manipulation. An attacker can remotely exploit this flaw without requiring authentication or user interaction, by crafting specially designed requests that inject SQL commands through the 'usid' argument. This can lead to unauthorized access or modification of the underlying database, potentially exposing sensitive tenant or property management data, corrupting records, or enabling further attacks such as privilege escalation or data exfiltration. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, and no need for privileges or user interaction, but with limited impact on confidentiality, integrity, and availability. Although no known exploits are currently observed in the wild, the public availability of exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is used for managing apartment-related information, making it a critical component for property management organizations relying on this software.

For European organizations, especially property management companies, housing associations, and real estate firms using the itsourcecode Apartment Management System 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of tenant personal data, lease agreements, payment records, and other sensitive information, potentially violating GDPR requirements and resulting in legal and financial penalties. Data integrity could be compromised, leading to incorrect billing, tenant disputes, or operational disruptions. Availability impacts may be limited but could occur if attackers manipulate database contents or cause application failures. Given the remote and unauthenticated nature of the exploit, attackers can target these systems from anywhere, increasing the threat surface. The exposure of sensitive personal and financial data could also damage organizational reputation and trust with tenants and partners.

Organizations should immediately assess whether they are running itsourcecode Apartment Management System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement input validation and parameterized queries or prepared statements to sanitize the 'usid' parameter and prevent SQL injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection payloads targeting the vulnerable endpoint. Conduct thorough code reviews and penetration testing focusing on the /report/unit_status_info.php file and related input handling. Restrict network access to the management system to trusted IP addresses where feasible, and monitor logs for unusual query patterns or repeated failed attempts. Additionally, ensure regular backups of the database are maintained to enable recovery in case of data corruption. Educate staff on the risks and signs of exploitation to enhance detection and response capabilities.
