CVE-2025-5693 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Human Metapneumovirus Testing Management System, specifically within the /bwdates-report-result.php file. The vulnerability arises from improper sanitization of the 'fromdate' and 'todate' parameters, which are used to filter or generate reports based on date ranges. An attacker can remotely manipulate these parameters to inject malicious SQL code, potentially altering the intended SQL queries executed by the backend database. This can lead to unauthorized data access, data modification, or even complete compromise of the database. The vulnerability does not require user authentication or interaction, making it accessible to unauthenticated remote attackers. The CVSS 4.0 base score is 5.3, indicating a medium severity level, with attack vector being network-based, low attack complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is low, suggesting that while exploitation is possible, the scope of damage may be limited or mitigated by other factors such as database permissions or application logic. No known exploits are currently observed in the wild, and no patches have been published yet. The disclosure date is June 5, 2025, indicating this is a recent vulnerability. Given the nature of the application—a medical testing management system—there is a risk of exposure or manipulation of sensitive health data if exploited.

For European organizations, especially healthcare providers and laboratories using the PHPGurukul Human Metapneumovirus Testing Management System, this vulnerability poses a risk of unauthorized access to patient test results and related sensitive health information. Exposure of such data could lead to violations of GDPR and other data protection regulations, resulting in legal and financial repercussions. Additionally, manipulation of test data could undermine the integrity of diagnostic results, potentially affecting patient care and public health responses. While the CVSS score suggests medium severity, the critical nature of healthcare data elevates the potential impact. Organizations relying on this system may face operational disruptions if attackers exploit the vulnerability to corrupt or delete data. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks if the system is accessible over the internet or poorly segmented within internal networks.

1. Immediate mitigation should include restricting external access to the affected application, especially the /bwdates-report-result.php endpoint, through network segmentation and firewall rules. 2. Implement input validation and parameterized queries or prepared statements in the application code to sanitize 'fromdate' and 'todate' parameters, preventing SQL injection. 3. Monitor application logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. 4. Conduct a thorough security audit of the entire application to identify and remediate similar injection flaws. 5. If possible, deploy a Web Application Firewall (WAF) with rules targeting SQL injection attempts to provide an additional layer of defense. 6. Engage with the vendor or development team to obtain or develop patches addressing this vulnerability. 7. Educate IT and security teams about the vulnerability and ensure incident response plans are updated to handle potential exploitation scenarios. 8. Regularly back up databases and verify backup integrity to enable recovery in case of data tampering or loss.
