CVE-2025-63512 identifies a critical SQL Injection vulnerability in the kishan0725 Hospital Management System version 4, specifically in the admin-panel1.php script used for deleting doctor records. The vulnerability is due to improper handling of the 'demail' parameter, which is incorporated directly into a dynamic SQL query without adequate sanitization or use of parameterized statements. This flaw allows an attacker to craft malicious input that alters the intended SQL command, potentially enabling unauthorized access to or manipulation of the underlying database. Such an injection can lead to data leakage, unauthorized data modification, or even complete compromise of the database server. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although no public exploits have been reported yet, the nature of SQL Injection vulnerabilities makes them attractive targets for attackers, especially in healthcare environments where sensitive patient and operational data are stored. The lack of a patch or mitigation guidance in the provided information underscores the urgency for organizations to audit their code and implement secure coding practices. The vulnerability's presence in a hospital management system amplifies its impact due to the critical nature of healthcare data confidentiality and availability.

For European organizations, particularly healthcare providers using the kishan0725 Hospital Management System, this vulnerability could lead to severe data breaches involving patient records, medical histories, and administrative data. Unauthorized access or manipulation of such data could result in privacy violations, regulatory non-compliance (e.g., GDPR), reputational damage, and operational disruptions in hospital services. Attackers exploiting this flaw could delete or alter critical records, potentially impacting patient care and hospital administration. The breach of sensitive healthcare data could also lead to financial penalties and loss of trust from patients and partners. Given the critical role of healthcare infrastructure, exploitation could have cascading effects on public health and safety. The absence of known exploits currently provides a window for proactive mitigation, but the risk remains high due to the ease of exploitation inherent in SQL Injection vulnerabilities.

Organizations should immediately conduct a thorough code review of the admin-panel1.php file and any other components handling user input to ensure all SQL queries use parameterized statements or prepared queries. Input validation should be enforced on the 'demail' parameter to restrict input to expected formats, such as validated email addresses. Access to the admin panel should be tightly controlled using multi-factor authentication and network segmentation to limit exposure. Implementing web application firewalls (WAFs) with SQL Injection detection rules can provide an additional layer of defense. Regular security assessments and penetration testing should be conducted to identify and remediate similar vulnerabilities. Organizations should monitor logs for suspicious activity related to the deletion functionality and prepare incident response plans specific to database compromise scenarios. Finally, vendors should be engaged to provide patches or updates, and organizations should plan for timely deployment once available.
