CVE-2025-5365 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Hospital Management System, specifically within the /admin/patient-search.php file. The vulnerability arises from improper sanitization or validation of the 'searchdata' parameter, which is used in SQL queries to search patient records. An attacker can remotely exploit this flaw by injecting malicious SQL code through the 'searchdata' argument, potentially manipulating the backend database. This can lead to unauthorized data access, data modification, or even complete compromise of the database. The vulnerability does not require authentication or user interaction, making it accessible to unauthenticated remote attackers. The CVSS 4.0 score is 6.9 (medium severity), reflecting the ease of exploitation (network vector, low attack complexity) but limited impact on confidentiality, integrity, and availability (low to limited impact). No known exploits are currently reported in the wild, but public disclosure increases the risk of exploitation. The lack of available patches or mitigation guidance from the vendor increases the urgency for organizations to implement protective measures. Given the critical nature of patient data and the role of hospital management systems in healthcare delivery, exploitation could lead to significant privacy violations, disruption of healthcare services, and regulatory non-compliance.

For European organizations, particularly healthcare providers using Campcodes Online Hospital Management System 1.0, this vulnerability poses a significant risk to patient data confidentiality and system integrity. Exploitation could result in unauthorized disclosure of sensitive health information, violating GDPR and other data protection regulations, leading to legal penalties and reputational damage. Additionally, manipulation of patient records could disrupt clinical workflows, potentially endangering patient safety. The healthcare sector is a high-value target in Europe, often targeted by cybercriminals and state-sponsored actors. The ability to exploit this vulnerability remotely without authentication increases the likelihood of attacks, especially in environments where the system is exposed to the internet or insufficiently segmented networks. The absence of patches means organizations must rely on compensating controls to mitigate risk. The impact extends beyond data breaches to operational disruption, undermining trust in healthcare IT systems.

1. Immediate network-level protections: Restrict access to the /admin/patient-search.php endpoint using firewalls or web application firewalls (WAFs) to allow only trusted IP addresses, ideally internal networks or VPNs. 2. Input validation and sanitization: Implement strict input validation on the 'searchdata' parameter to reject or sanitize malicious input, using parameterized queries or prepared statements if possible. 3. Application-layer WAF rules: Deploy WAF rules specifically targeting SQL injection patterns on the vulnerable parameter. 4. Network segmentation: Isolate the hospital management system from public networks and limit exposure to reduce attack surface. 5. Monitoring and logging: Enable detailed logging of access to the vulnerable endpoint and monitor for unusual query patterns or spikes in failed searches indicative of exploitation attempts. 6. Vendor engagement: Engage with Campcodes for patches or official guidance and plan for timely updates once available. 7. Incident response readiness: Prepare to respond to potential data breaches or system compromises, including data backup and recovery plans. 8. Consider temporary disabling or restricting the patient search functionality if feasible until a patch is available.
