CVE-2025-9793 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System, specifically within the /setting/admin.php file's Setting Handler component. The vulnerability arises from improper sanitization or validation of the 'ddlBranch' argument, which allows an attacker to manipulate SQL queries executed by the application. This flaw enables remote attackers to inject arbitrary SQL code without requiring authentication or user interaction, potentially leading to unauthorized data access or modification. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is limited but present (VC:L, VI:L, VA:L), and the exploitability is partially confirmed (E:P). Although no known exploits are currently reported in the wild, the exploit code is publicly available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, and no official patches or mitigation links have been published yet. Given the nature of SQL Injection, successful exploitation could allow attackers to extract sensitive data, modify or delete database records, or potentially escalate privileges within the application environment.

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. Compromise could lead to unauthorized disclosure of personally identifiable information (PII), financial records, or operational data, which may violate GDPR and other data protection regulations, resulting in legal and financial repercussions. Additionally, data tampering could disrupt apartment management operations, causing service outages or incorrect billing. The remote and unauthenticated nature of the vulnerability increases the likelihood of exploitation, especially in organizations with internet-facing management portals. The lack of patches and public exploit availability further heightens the urgency for mitigation. Organizations may also face reputational damage if tenant data is exposed or manipulated. The impact is particularly critical for property management companies handling large volumes of sensitive tenant data or operating in regulated environments.

1. Immediate mitigation should include restricting external access to the /setting/admin.php endpoint by implementing network-level controls such as firewalls or VPNs to limit access to trusted administrators only. 2. Employ Web Application Firewalls (WAFs) configured to detect and block SQL Injection patterns targeting the 'ddlBranch' parameter. 3. Conduct a thorough code review and implement proper input validation and parameterized queries or prepared statements to eliminate SQL Injection risks in the affected component. 4. Monitor application logs for suspicious activity related to the 'ddlBranch' parameter and unusual database queries. 5. If possible, isolate the affected system from critical networks until a patch or update is available. 6. Engage with the vendor or community to obtain or develop patches and apply them promptly once released. 7. Educate administrative users on recognizing potential signs of compromise and enforce strong authentication mechanisms to reduce overall risk exposure. 8. Perform regular backups of databases and configuration files to enable recovery in case of data tampering.
