CVE-2025-5694 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Human Metapneumovirus Testing Management System, specifically within the /search-report-result.php file. The vulnerability arises from improper sanitization or validation of the 'serachdata' parameter, which an attacker can manipulate to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries on the backend database. The vulnerability is exploitable over the network without requiring user interaction or elevated privileges, increasing its risk profile. However, the CVSS 4.0 vector indicates a requirement for low privileges (PR:L), suggesting some form of limited authentication or access control is needed to exploit it. The impact on confidentiality, integrity, and availability is rated as low, which aligns with the medium severity classification and a CVSS score of 5.3. This suggests that while the vulnerability can be exploited remotely, the scope or impact of the SQL injection is somewhat limited, possibly due to restricted database permissions or partial query control. No public exploits are currently known in the wild, and no patches have been published yet. The vulnerability disclosure is recent (June 2025), and the affected product is a specialized medical testing management system used for Human Metapneumovirus testing, which is a respiratory virus. The lack of CWE classification and patch links indicates that remediation guidance may be limited at this time.

For European organizations, especially healthcare providers and laboratories utilizing the PHPGurukul Human Metapneumovirus Testing Management System, this vulnerability poses a risk to the confidentiality and integrity of sensitive patient data and test results. Exploitation could lead to unauthorized access to medical records, manipulation of test outcomes, or disruption of testing workflows. Given the critical nature of healthcare data under GDPR, any data breach or integrity compromise could result in significant regulatory penalties and loss of patient trust. Additionally, compromised test management systems could delay diagnosis and treatment, impacting public health responses. Although the CVSS score and severity are medium, the specialized nature of the system and the sensitivity of the data it handles elevate the potential impact. The remote exploitability without user interaction increases the urgency for affected organizations to assess their exposure. However, the limited availability of the affected product and the requirement for some level of privilege may reduce the overall risk to large-scale European healthcare infrastructure.

Organizations using the affected PHPGurukul system should immediately conduct a security review of their deployment, focusing on access controls around the /search-report-result.php functionality. Since no official patches are currently available, applying web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'serachdata' parameter is recommended. Restricting access to the vulnerable endpoint to trusted internal networks or VPN users can reduce exposure. Database accounts used by the application should follow the principle of least privilege, limiting SQL commands to only those necessary for normal operation to minimize potential damage from injection. Regularly monitoring logs for unusual query patterns or errors related to SQL injection attempts is critical. Organizations should engage with PHPGurukul for timely patch releases and consider implementing input validation and parameterized queries as long-term fixes. Additionally, conducting penetration testing focused on injection flaws can help identify other potential weaknesses.
