CVE-2025-5858 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Nipah Virus Testing Management System, specifically in the /patient-report.php file. The vulnerability arises from improper sanitization or validation of the 'searchdata' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the underlying database. This could lead to data leakage, data corruption, or unauthorized administrative actions within the system. The vulnerability does not require user interaction and can be exploited remotely with low attack complexity. The CVSS 4.0 score is 5.3 (medium severity), reflecting limited impact on confidentiality, integrity, and availability, and requiring low privileges (PR:L) but no authentication or user interaction. Although no public exploits are currently known in the wild, the vulnerability details have been disclosed publicly, increasing the risk of exploitation. The affected product is a specialized healthcare management system used for Nipah virus testing, which likely handles sensitive patient data and test results. Given the critical nature of healthcare data and the potential for disruption in public health monitoring, this vulnerability poses a significant risk if exploited.

For European organizations, particularly healthcare providers and public health authorities involved in infectious disease management, this vulnerability could have serious consequences. Exploitation could lead to unauthorized disclosure of sensitive patient information, violating GDPR and other privacy regulations, resulting in legal and financial penalties. Data integrity could be compromised, leading to incorrect patient reports or test results, which may hinder effective disease control and response efforts. Availability impacts appear limited but cannot be ruled out if attackers escalate their access. The vulnerability's remote exploitability and lack of user interaction requirement increase the risk of automated attacks or targeted intrusions. European healthcare systems are increasingly digitized and interconnected, making such vulnerabilities critical to address promptly to maintain trust and operational continuity in public health infrastructure.

Specific mitigation steps include: 1) Immediate application of patches or updates from PHPGurukul once available; if no official patch exists, implement input validation and parameterized queries or prepared statements in the /patient-report.php script to sanitize the 'searchdata' input. 2) Conduct thorough code reviews and penetration testing focused on SQL injection vectors within the application. 3) Deploy Web Application Firewalls (WAFs) configured to detect and block SQL injection attempts targeting this parameter. 4) Monitor logs for unusual query patterns or repeated failed attempts to exploit 'searchdata'. 5) Restrict database user privileges used by the application to the minimum necessary to limit the impact of any successful injection. 6) Educate system administrators and developers about secure coding practices and the importance of timely patching. 7) For organizations using this system, consider network segmentation and additional access controls to limit exposure. 8) Prepare incident response plans specific to healthcare data breaches to respond swiftly if exploitation occurs.
