CVE-2024-0364 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Hospital Management System, specifically within the admin/query-details.php file. The vulnerability arises from improper sanitization and validation of the 'adminremark' parameter, which allows an attacker to inject malicious SQL code. This flaw can be exploited by an authenticated user with low privileges (PR:L) over an adjacent network (AV:A) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability of the underlying database, as it allows unauthorized reading, modification, or deletion of sensitive hospital management data. The CVSS 3.1 base score is 5.5, categorized as medium severity, reflecting the requirement for some privileges and network proximity for exploitation. Although no public exploits are currently known in the wild, the vulnerability has been disclosed publicly, increasing the risk of future exploitation. Given the critical nature of healthcare data, even a medium severity SQL injection can have serious consequences if leveraged by attackers to access patient records, alter medical data, or disrupt hospital operations.

For European organizations, particularly hospitals and healthcare providers using PHPGurukul Hospital Management System version 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive patient information, violating GDPR regulations and potentially resulting in severe legal and financial penalties. Data integrity could be compromised, leading to incorrect medical records and treatment errors. Availability impacts could disrupt hospital workflows and patient care services. The requirement for authenticated access limits exposure but does not eliminate risk, as insider threats or compromised credentials could be leveraged. Additionally, the vulnerability's presence in a healthcare system makes it an attractive target for ransomware or data theft campaigns, which have been increasingly targeting European healthcare institutions.

Immediate mitigation should focus on restricting access to the admin interface to trusted personnel and networks, employing strong authentication mechanisms such as multi-factor authentication to reduce the risk of credential compromise. Input validation and parameterized queries or prepared statements should be implemented in the admin/query-details.php file to eliminate SQL injection vectors. Since no official patch is currently available, organizations should consider code review and manual remediation of the vulnerable parameter. Network segmentation and monitoring for unusual database queries or access patterns can help detect exploitation attempts. Regular backups of critical data should be maintained to enable recovery in case of data corruption or deletion. Finally, organizations should engage with PHPGurukul or community forums for updates or patches and plan for timely application once available.
