CVE-2025-6407 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Hospital Management System, specifically within the /user-login.php endpoint. The vulnerability arises from improper sanitization of the 'Username' parameter, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables an attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or even complete compromise of the database. Given that the vulnerability is remotely exploitable with low attack complexity and no privileges or user interaction needed, it poses a significant risk to the confidentiality, integrity, and availability of sensitive hospital data. Although the CVSS 4.0 base score is 6.9 (medium severity), the exploitability and potential impact on critical healthcare data elevate the threat's seriousness. No official patches are currently available, and while no known exploits are reported in the wild yet, public disclosure increases the risk of imminent exploitation. The vulnerability affects only version 1.0 of the product, which is a specialized hospital management system used to handle patient records, appointments, billing, and other sensitive healthcare operations.

For European organizations, especially healthcare providers using Campcodes Online Hospital Management System 1.0, this vulnerability could lead to severe consequences. Exploitation could result in unauthorized disclosure of patient records, violating GDPR and other data protection regulations, leading to legal penalties and reputational damage. Integrity of medical data could be compromised, potentially affecting patient care and safety. Availability of the hospital management system could be disrupted, impacting hospital operations and emergency response capabilities. Furthermore, healthcare data is a prime target for ransomware and espionage, increasing the risk of secondary attacks. The critical nature of healthcare services in Europe means that exploitation could have cascading effects on public health infrastructure and trust in digital health systems.

Immediate mitigation should focus on implementing input validation and parameterized queries or prepared statements in the /user-login.php script to prevent SQL injection. Since no official patch is available, organizations should conduct a thorough code review and apply custom fixes to sanitize the 'Username' input rigorously. Deploying a Web Application Firewall (WAF) with rules specifically targeting SQL injection patterns can provide a temporary protective barrier. Monitoring and logging login attempts for unusual patterns can help detect exploitation attempts early. Network segmentation should be enforced to isolate the hospital management system from other critical infrastructure. Organizations should also prepare incident response plans tailored to potential data breaches involving patient information. Finally, organizations must plan to upgrade to a patched version once available and consider alternative systems if immediate patching is not feasible.
