CVE-2025-5246 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Hospital Management System, specifically within the /hms/admin/query-details.php file. The vulnerability arises from improper sanitization or validation of the 'adminremark' parameter, which is directly used in SQL queries. An attacker can remotely manipulate this parameter without requiring authentication or user interaction, allowing them to inject malicious SQL code. This can lead to unauthorized access to the underlying database, potentially exposing sensitive patient data, modifying or deleting records, or even escalating privileges within the system. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with attack vector as network (remote), low attack complexity, no privileges or user interaction required, and impacts on confidentiality, integrity, and availability rated as low. Although no public exploits are currently known to be in the wild, the disclosure of the vulnerability increases the risk of exploitation by threat actors targeting healthcare systems. Given the critical nature of hospital management systems, exploitation could disrupt healthcare operations and compromise patient privacy.

For European organizations, particularly hospitals and healthcare providers using the Campcodes Online Hospital Management System version 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive patient health information, violating GDPR requirements and resulting in legal and financial penalties. Data integrity could be compromised, affecting clinical decisions and patient safety. Availability impacts could disrupt hospital operations, delaying treatments and emergency responses. The healthcare sector in Europe is a high-value target for cybercriminals and nation-state actors, increasing the likelihood of targeted attacks. Furthermore, the lack of authentication and user interaction requirements lowers the barrier for attackers, potentially enabling widespread exploitation if the system is internet-facing or accessible via internal networks.

Immediate mitigation should focus on applying patches or updates from the vendor; however, no patch links are currently provided, so organizations must engage with Campcodes for remediation. In the interim, organizations should implement web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the 'adminremark' parameter. Input validation and sanitization should be enforced at the application level, ensuring all user-supplied data is properly escaped or parameterized in SQL queries. Network segmentation should isolate the hospital management system from public-facing networks to reduce exposure. Monitoring and logging of database queries and application logs should be enhanced to detect anomalous activities indicative of exploitation attempts. Regular security assessments and penetration testing focused on injection flaws are recommended. Additionally, organizations should review and strengthen access controls and backup procedures to ensure rapid recovery in case of data compromise or loss.
