CVE-2025-5362 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Hospital Management System, specifically within the /admin/doctor-specilization.php file. The vulnerability arises from improper sanitization or validation of the 'doctorspecilization' parameter, which is directly used in SQL queries. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the backend database. Exploitation does not require any user interaction or privileges, making it remotely exploitable over the network. Although the CVSS 4.0 score is 6.9 (medium severity), the vulnerability is classified as critical in the description, reflecting the high risk associated with SQL injection in healthcare systems. Successful exploitation could lead to unauthorized data access, data modification, or even full compromise of the database, impacting confidentiality, integrity, and availability of sensitive patient and hospital data. The vulnerability is publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The lack of available patches or mitigations from the vendor further elevates the threat level for organizations using this software version.

For European healthcare organizations using Campcodes Online Hospital Management System 1.0, this vulnerability poses a significant risk. Healthcare data is highly sensitive and protected under regulations such as GDPR, so unauthorized access or data breaches could result in severe legal and financial consequences. Attackers exploiting this vulnerability could extract patient records, alter medical data, or disrupt hospital operations, potentially endangering patient safety. The ability to remotely exploit without authentication increases the attack surface, especially for hospitals with externally accessible management portals. Additionally, the compromise of hospital systems can lead to reputational damage and loss of trust. Given the critical nature of healthcare services, any disruption or data breach could have cascading effects on public health infrastructure in Europe.

Organizations should immediately assess their use of Campcodes Online Hospital Management System version 1.0 and prioritize upgrading to a patched or newer version once available. In the absence of an official patch, implement web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'doctorspecilization' parameter. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters used in SQL queries. Restrict external access to the administration interface by network segmentation and VPN access only. Monitor logs for suspicious database queries or unusual activity related to the affected endpoint. Engage with the vendor for timely updates and consider alternative hospital management solutions if remediation is delayed. Regular security audits and penetration testing focused on injection flaws should be conducted to identify and mitigate similar vulnerabilities.
