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 due to improper sanitization or validation of the 'firstname' parameter, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This injection flaw could potentially allow an attacker to manipulate backend database queries, leading to unauthorized data access, modification, or deletion. Although the CVSS 4.0 vector indicates a network attack vector with low complexity and no privileges or user interaction required, the impact on confidentiality, integrity, and availability is limited to low levels, suggesting partial exposure or mitigated impact. The vulnerability may also affect other parameters, increasing the attack surface. No patches have been officially released yet, and while public exploit details exist, there are no known exploits actively observed in the wild. Given the nature of the affected system—a clinic management platform—successful exploitation could expose sensitive patient data, disrupt clinical operations, or corrupt medical records, posing significant risks to healthcare providers and patients alike.

For European organizations, particularly healthcare providers using the itsourcecode Online Clinic Management System 1.0, this vulnerability presents a tangible risk to patient data confidentiality and system integrity. Exploitation could lead to unauthorized disclosure of sensitive personal health information (PHI), violating GDPR requirements and potentially resulting in regulatory penalties and reputational damage. Additionally, manipulation or corruption of clinical data could disrupt healthcare delivery, impacting patient safety and operational continuity. The remote and unauthenticated nature of the attack vector increases the likelihood of exploitation, especially if exposed to the internet without adequate network protections. Given the criticality of healthcare services, even a medium-severity vulnerability warrants prompt attention to prevent cascading effects on service availability and trust in healthcare IT systems.

To mitigate this vulnerability, European healthcare organizations should immediately audit their deployment of the itsourcecode Online Clinic Management System to identify affected versions. Since no official patches are currently available, organizations should implement compensating controls such as deploying web application firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the 'firstname' parameter and other input fields. Input validation and sanitization should be enforced at the application level, ideally by updating or customizing the source code to use parameterized queries or prepared statements. Network segmentation should be employed to restrict external access to the clinic management system, limiting exposure to trusted internal networks only. Regular monitoring and logging of database queries and application logs should be enhanced to detect anomalous activities indicative of exploitation attempts. Finally, organizations should prepare for timely patching once an official fix is released by the vendor and consider conducting penetration testing to validate the effectiveness of applied mitigations.
