CVE-2025-13567 is a SQL injection vulnerability identified in the itsourcecode COVID Tracking System version 1.0. The vulnerability exists in the /admin/?page=establishment endpoint, where the ID parameter is improperly sanitized, allowing attackers to inject malicious SQL commands. This flaw can be exploited remotely without requiring user interaction or elevated privileges, although some level of low privilege (PR:L) is needed, possibly meaning a logged-in user with limited rights. The injection can lead to unauthorized reading, modification, or deletion of sensitive data stored in the backend database, impacting confidentiality, integrity, and availability. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the ease of exploitation (low complexity, no user interaction), but limited scope and impact due to the requirement of some privileges and limited confidentiality/integrity/availability impact. No patches or official fixes have been published yet, and while no active exploits are reported in the wild, the public availability of exploit code increases the risk of attacks. The vulnerability highlights the critical need for secure coding practices such as input validation and the use of parameterized queries in web applications, especially those handling sensitive public health data during a pandemic. The affected system is likely used by public health authorities or organizations tracking COVID-19 data, making it a valuable target for attackers seeking to disrupt health data integrity or steal sensitive information.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of COVID-19 tracking data, which may include sensitive personal health information. Exploitation could lead to unauthorized data disclosure, manipulation of health records, or disruption of tracking services, undermining public health efforts and trust. Given the critical nature of pandemic response data, any compromise could have cascading effects on health policy decisions and resource allocation. Additionally, data breaches involving health information are subject to strict regulatory penalties under GDPR, increasing legal and financial risks. The availability impact is moderate but could affect administrative functions critical for managing establishments in the tracking system. Organizations relying on this software without timely mitigation may face reputational damage and operational disruptions. The remote exploitability and public availability of exploit code increase the likelihood of attacks, especially from opportunistic or targeted threat actors aiming to exploit pandemic-related systems.

1. Immediately implement input validation and sanitization on all parameters, especially the ID parameter in the /admin/?page=establishment endpoint. 2. Refactor the backend code to use parameterized queries or prepared statements to prevent SQL injection. 3. Restrict access to the administration interface using network segmentation, VPNs, or IP whitelisting to limit exposure. 4. Enforce the principle of least privilege for user accounts accessing the system, ensuring minimal rights are granted. 5. Monitor logs for unusual database queries or access patterns indicative of injection attempts. 6. If patches become available from itsourcecode, apply them promptly. 7. Conduct a thorough security audit of the entire application to identify and remediate other potential injection points. 8. Educate administrators and developers on secure coding practices and the importance of timely vulnerability management. 9. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block SQL injection attempts targeting this system. 10. Backup critical data regularly and ensure recovery procedures are tested to mitigate potential data loss from exploitation.
