CVE-2025-13569 identifies a SQL injection vulnerability in the itsourcecode COVID Tracking System version 1.0, specifically within the /admin/?page=city endpoint. The vulnerability arises from improper sanitization of the 'ID' parameter, allowing an attacker to inject malicious SQL code remotely without requiring user interaction or elevated privileges beyond low-level access. This flaw can be exploited to manipulate backend database queries, potentially leading to unauthorized data disclosure, modification, or deletion. The vulnerability has a CVSS 4.0 base score of 5.3, indicating medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, and no user interaction needed. The impact affects confidentiality, integrity, and availability to a limited extent, as the vulnerability is confined to a specific administrative function. Although no active exploits have been reported in the wild, the public disclosure of the exploit code increases the risk of exploitation. The COVID Tracking System is critical for managing pandemic-related data, making the integrity and confidentiality of its data paramount. The lack of available patches at the time of disclosure highlights the need for immediate mitigation steps to reduce exposure.

For European organizations utilizing the itsourcecode COVID Tracking System, this vulnerability poses risks including unauthorized access to sensitive health and location data, potential data tampering, and disruption of COVID tracking operations. Compromise of this system could undermine public health efforts, erode trust in digital health infrastructure, and expose personally identifiable information (PII) of citizens. Given the administrative nature of the vulnerable endpoint, attackers could escalate their access or pivot to other internal systems. The medium severity suggests moderate impact, but the critical role of COVID tracking systems in pandemic response elevates the operational risk. Organizations may face regulatory repercussions under GDPR if personal data is exposed. Additionally, the remote exploitability without user interaction increases the likelihood of automated attacks targeting vulnerable installations.

1. Immediately restrict access to the /admin interface using network-level controls such as VPNs, IP whitelisting, or firewall rules to limit exposure. 2. Implement strict input validation and parameterized queries or prepared statements in the application code to prevent SQL injection. 3. Monitor logs for suspicious activity targeting the 'ID' parameter or the /admin/?page=city endpoint. 4. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts against this endpoint. 5. Coordinate with the vendor to obtain and apply security patches or updates as soon as they become available. 6. Conduct a security audit of the entire COVID Tracking System to identify and remediate other potential injection points. 7. Educate administrators on the risks and signs of exploitation to enable rapid incident response. 8. Consider isolating the COVID Tracking System from other critical infrastructure to contain potential breaches.
