CVE-2025-10618 is a medium severity SQL Injection vulnerability identified in version 1.0 of the itsourcecode Online Clinic Management System, specifically within the transact.php file. The vulnerability arises from improper sanitization or validation of the 'firstname' parameter, which can be manipulated by an attacker to inject malicious SQL code. This flaw allows an unauthenticated remote attacker with low privileges to execute arbitrary SQL commands on the backend database without requiring user interaction. The vulnerability potentially compromises the confidentiality, integrity, and availability of the system's data, as attackers could extract sensitive patient information, modify records, or disrupt service operations. Although the CVSS score is 5.3, indicating a medium severity, the presence of remote exploitability and the critical nature of healthcare data elevate the risk profile. The vulnerability may also affect other parameters beyond 'firstname,' suggesting a broader input validation issue within the application. No patches or fixes have been published yet, and no known exploits are currently observed in the wild, but public disclosure increases the risk of exploitation attempts. The Online Clinic Management System is likely used by healthcare providers to manage patient records, appointments, and transactions, making the system a high-value target for attackers seeking to access sensitive medical data or disrupt healthcare services.

For European organizations, particularly healthcare providers using the itsourcecode Online Clinic Management System 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to sensitive patient health information, violating GDPR requirements and potentially resulting in substantial regulatory fines and reputational damage. Data integrity could be compromised, leading to incorrect patient records, which may adversely affect patient care and safety. Availability impacts could disrupt clinical operations, causing delays in treatment and administrative processes. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially in environments with internet-facing clinic management portals. Given the criticality of healthcare services, any disruption or data breach could have severe consequences for patient trust and organizational compliance within the European healthcare sector.

European healthcare organizations using this system should immediately conduct a thorough security assessment of their Online Clinic Management System installations. Specific mitigations include: 1) Implementing strict input validation and parameterized queries or prepared statements in the transact.php file and other affected modules to prevent SQL injection. 2) Applying web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'firstname' parameter and similar inputs. 3) Restricting database user privileges to the minimum necessary to limit the impact of potential SQL injection exploits. 4) Monitoring logs for unusual database query patterns or failed injection attempts to enable early detection. 5) Isolating the clinic management system behind secure network segments and VPNs to reduce exposure. 6) Engaging with the vendor or community to obtain patches or updates as soon as they become available. 7) Conducting regular security training for developers and administrators on secure coding and input validation best practices. These measures go beyond generic advice by focusing on immediate containment, detection, and hardening specific to the known vulnerable parameter and the healthcare context.
