CVE-2025-9601 is a SQL Injection vulnerability identified in itsourcecode Apartment Management System version 1.0, specifically within the /setting/employee_salary_setup.php file. The vulnerability arises from improper sanitization or validation of the input parameter ddlEmpName, which an attacker can manipulate to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database without requiring user interaction or privileges. The vulnerability is exploitable over the network (AV:N), with low attack complexity (AC:L), no authentication required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), indicating that while the attacker can potentially extract or modify some data, the scope and severity of damage are somewhat constrained. The CVSS v4.0 base score is 6.9, categorizing it as a medium severity issue. The exploit code has been publicly disclosed, increasing the risk of exploitation, although no known active exploitation in the wild has been reported yet. The vulnerability affects only version 1.0 of the product, which is a niche apartment management software likely used by property management companies to handle employee salary setups and related administrative tasks. Given the nature of the vulnerability, attackers could leverage this flaw to access sensitive employee salary data, modify payroll information, or potentially escalate attacks within the affected environment if combined with other vulnerabilities or misconfigurations.

For European organizations using the itsourcecode Apartment Management System 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of employee payroll data. Unauthorized access or manipulation of salary information could lead to financial fraud, insider threats, or reputational damage. Additionally, if attackers gain deeper access through this injection point, they might pivot to other internal systems, potentially compromising broader organizational assets. Although the vulnerability does not directly impact availability, the potential for data corruption or unauthorized data disclosure could disrupt HR and payroll operations. Given the GDPR regulations in Europe, any data breach involving personal or financial employee data could result in significant legal and financial penalties. The medium severity rating suggests that while the threat is serious, it may not lead to full system compromise without additional vulnerabilities or poor security practices.

1. Immediate patching or upgrading to a fixed version of the itsourcecode Apartment Management System is the most effective mitigation, although no patch links are currently provided; organizations should contact the vendor for updates or advisories. 2. Implement strict input validation and parameterized queries (prepared statements) in the affected codebase to prevent SQL injection attacks. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the ddlEmpName parameter. 4. Conduct thorough code reviews and security testing (including automated static and dynamic analysis) of the application to identify and remediate similar injection flaws. 5. Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. 6. Monitor logs for unusual database queries or access patterns related to employee salary setups. 7. Isolate the apartment management system within a segmented network zone to reduce lateral movement risks. 8. Educate IT and security teams about this vulnerability and ensure incident response plans include steps for SQL injection incidents.
