CVE-2025-4026 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Nipah Virus Testing Management System, specifically affecting the /profile.php file. The vulnerability arises due to improper sanitization or validation of user-supplied input in the parameters 'adminname' and 'mobilenumber'. An attacker can manipulate these parameters to inject malicious SQL code, which the backend database executes. This can lead to unauthorized data access, data modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. Although the CVSS 4.0 score is 6.9 (medium severity), the classification as critical by the original source suggests the potential for significant impact depending on the deployment context. The system in question is used for managing Nipah virus testing data, which likely contains sensitive health information, making the data at risk highly sensitive. No patches or mitigations have been publicly disclosed yet, and while no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the risk of exploitation.

For European organizations, particularly healthcare providers, public health agencies, and laboratories involved in infectious disease management, this vulnerability poses a serious risk. Exploitation could lead to unauthorized access to sensitive patient data, including personal identifiers and health status related to Nipah virus testing. This could result in privacy violations under GDPR, reputational damage, and potential disruption of critical health services. The integrity of test results could be compromised, leading to incorrect diagnoses or public health responses. Availability could also be affected if attackers manipulate or delete data, impacting the ability to track and respond to outbreaks effectively. Given the critical nature of infectious disease management, any compromise could have broader public health implications.

Organizations using the PHPGurukul Nipah Virus Testing Management System should immediately conduct a thorough code review focusing on input validation and sanitization in /profile.php, especially for the 'adminname' and 'mobilenumber' parameters. Implement parameterized queries or prepared statements to prevent SQL injection. If possible, isolate the system from direct internet exposure and restrict access to trusted networks. Monitor logs for unusual database queries or access patterns indicative of exploitation attempts. Since no official patch is available, consider applying virtual patching via web application firewalls (WAF) configured to detect and block SQL injection attempts targeting these parameters. Additionally, conduct a risk assessment to evaluate the sensitivity of stored data and prepare incident response plans in case of compromise. Regular backups and integrity checks of the database should be enforced to enable recovery from potential data tampering.
