CVE-2025-5602 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Hospital Management System, specifically within an unspecified function in the /admin/registration.php file. The vulnerability arises from improper sanitization or validation of the 'full_name' parameter, which can be manipulated by an attacker 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 classified with 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 low to limited, suggesting that while data exposure or modification is possible, the scope or depth of impact is somewhat constrained. No known exploits are currently observed in the wild, and no patches or mitigations have been publicly disclosed at the time of publication. Given the nature of hospital management systems, which typically handle sensitive patient and operational data, exploitation could lead to unauthorized data access, data manipulation, or disruption of hospital administrative functions. The vulnerability's presence in an administrative registration module suggests potential for abuse in user or patient record management processes.

For European organizations, particularly healthcare providers using the Campcodes Hospital Management System version 1.0, this vulnerability poses a significant risk to patient data confidentiality and system integrity. Exploitation could lead to unauthorized access to sensitive patient records, potentially violating GDPR requirements for data protection and privacy. Data manipulation could disrupt hospital operations, affecting patient care and administrative workflows. Even though the CVSS score indicates medium severity, the critical nature of healthcare data amplifies the impact. Additionally, reputational damage and regulatory penalties could arise from breaches. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, especially if the system is exposed to the internet or insufficiently segmented within hospital networks. The lack of known exploits in the wild currently provides a window for proactive mitigation, but public disclosure increases the risk of future exploitation attempts.

European healthcare organizations using Campcodes Hospital Management System 1.0 should immediately conduct a thorough audit to identify affected installations. Specific mitigation steps include: 1) Implementing input validation and parameterized queries or prepared statements in the /admin/registration.php module to prevent SQL injection. 2) Restricting network access to the administrative interface by using firewalls, VPNs, or network segmentation to limit exposure to trusted personnel only. 3) Monitoring logs for unusual database queries or access patterns indicative of injection attempts. 4) Applying web application firewalls (WAFs) with rules targeting SQL injection signatures as an interim protective measure. 5) Engaging with the vendor for official patches or updates and prioritizing their deployment once available. 6) Conducting security awareness training for administrators to recognize and report suspicious activity. 7) Regularly backing up critical data and verifying backup integrity to enable recovery in case of data corruption or loss. These steps go beyond generic advice by focusing on immediate containment, detection, and remediation tailored to the specific vulnerability and healthcare context.
