CVE-2025-63512 identifies a SQL Injection vulnerability in the kishan0725 Hospital Management System version 4, specifically within the admin-panel1.php script's deleting doctor logic. The vulnerability stems from improper handling of the 'demail' parameter, which is incorporated directly into a dynamic SQL query without adequate sanitization or use of parameterized queries. This allows an unauthenticated attacker to craft malicious input that alters the intended SQL command, potentially enabling unauthorized reading or modification of the underlying database. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The CVSS v3.1 base score is 6.5, reflecting a medium severity level with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact primarily affects confidentiality and integrity, with no direct effect on availability. No patches or fixes are currently linked, and no known exploits have been reported in the wild. The vulnerability's presence in a hospital management system is particularly concerning due to the sensitive nature of healthcare data, including patient records and operational information. Exploitation could lead to data leakage, unauthorized data manipulation, or further compromise of the hospital's IT environment. The lack of authentication requirements and ease of remote exploitation increase the urgency for remediation. Organizations using this system should prioritize code review and implement parameterized queries or stored procedures to prevent SQL Injection. Additionally, monitoring database logs for anomalous queries and restricting database user permissions can help mitigate risk.

The primary impact of CVE-2025-63512 on European organizations lies in the potential compromise of sensitive healthcare data managed by the affected Hospital Management System. Successful exploitation could lead to unauthorized disclosure of patient information, violating data protection regulations such as GDPR, and damaging organizational reputation. Integrity of medical records could also be undermined, potentially affecting patient care and safety. Although availability is not directly impacted, the downstream effects of data corruption or breach investigations could disrupt hospital operations. The vulnerability requires no authentication and can be exploited remotely, increasing the risk of widespread attacks, especially in environments with exposed administrative interfaces. European healthcare providers using this system or similar legacy software with insufficient input validation are at heightened risk. The breach of confidential health data could also lead to regulatory fines and legal consequences under European data protection laws. Furthermore, attackers might leverage this vulnerability as an initial foothold for further network intrusion or ransomware deployment, compounding the impact. Overall, the threat poses a significant risk to the confidentiality and integrity of critical healthcare information systems in Europe.

To mitigate CVE-2025-63512, organizations should immediately review and update the affected Hospital Management System code to implement parameterized queries or prepared statements in place of dynamic SQL concatenation, particularly for the 'demail' parameter in admin-panel1.php. Input validation should be enforced to restrict inputs to expected formats, such as valid email addresses, reducing injection risk. If source code modification is not immediately feasible, deploying a Web Application Firewall (WAF) with rules targeting SQL Injection patterns can provide temporary protection. Restrict network access to the admin panel by implementing IP whitelisting or VPN-only access to reduce exposure. Database user accounts used by the application should have the least privileges necessary, preventing unauthorized data manipulation beyond what is required. Regularly audit database logs for suspicious queries indicative of injection attempts. Organizations should also conduct security assessments and penetration testing focused on injection vulnerabilities in all web-facing applications. Finally, maintain an inventory of all hospital management software versions in use to identify and prioritize vulnerable instances for patching or replacement. Coordination with software vendors for official patches or updates is recommended once available.
