CVE-2025-6156 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Nipah Virus Testing Management System, specifically within the /bwdates-report-ds.php file. The vulnerability arises from improper sanitization of the 'testtype' parameter, which is directly used in SQL queries without adequate validation or parameterization. This flaw allows an unauthenticated remote attacker with low privileges to manipulate the SQL query logic by injecting malicious SQL code through the 'testtype' argument. The vulnerability does not require user interaction and can be exploited over the network, making it accessible to attackers without physical or local access. The CVSS 4.0 base score is 5.3 (medium severity), reflecting limited impact on confidentiality, integrity, and availability, with no privileges required but some privileges needed (PR:L) and no user interaction (UI:N). The vulnerability's exploitability is rated as partially functional (E:P), and the impact on confidentiality, integrity, and availability is low (L). Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The affected system is a specialized management system used for Nipah Virus testing data, which likely stores sensitive health-related information and testing results. The SQL Injection could allow attackers to extract sensitive patient data, modify or delete records, or potentially escalate privileges within the system depending on the underlying database and application logic. The absence of a patch or mitigation guidance in the provided data indicates that organizations using this system must take immediate protective measures to prevent exploitation.

For European organizations, particularly healthcare providers, public health agencies, and laboratories involved in infectious disease testing and management, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive health data. Unauthorized access or manipulation of Nipah Virus testing data could lead to privacy violations, misinformation in public health reporting, and disruption of critical disease surveillance activities. Given the specialized nature of the system, exploitation could undermine trust in public health infrastructure and complicate outbreak response efforts. Although the CVSS score suggests medium severity, the potential impact on public health data integrity and confidentiality elevates the practical risk. Additionally, if attackers leverage this vulnerability to pivot within the network, it could lead to broader compromise of healthcare IT systems. The remote exploitability without user interaction increases the attack surface, especially for organizations with externally accessible instances of this system or insufficient network segmentation.

1. Immediate implementation of input validation and parameterized queries in the /bwdates-report-ds.php file to sanitize the 'testtype' parameter and prevent SQL Injection. 2. Restrict network access to the Nipah Virus Testing Management System to trusted internal networks or VPNs, minimizing exposure to the internet. 3. Conduct thorough code reviews and penetration testing focused on SQL Injection and other injection flaws within the application. 4. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection attempts targeting the 'testtype' parameter. 5. Monitor application logs for unusual or malformed SQL queries indicative of exploitation attempts. 6. Segregate the database and application servers with strict access controls to limit the impact of a potential breach. 7. Develop and apply patches promptly once available from the vendor or consider migrating to alternative solutions if patching is delayed. 8. Educate IT and security teams on the specific risks associated with this vulnerability and ensure incident response plans include scenarios involving SQL Injection in critical health systems.
