CVE-2025-10670 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode E-Logbook with Health Monitoring System for COVID-19. This system is designed to track and monitor health-related data, likely including sensitive personal and health information, to manage COVID-19 cases and contacts. The vulnerability exists in the processing of the /check_profile.php file, specifically in the handling of the 'profile_id' parameter. An attacker can manipulate this parameter to inject malicious SQL code, which the backend database executes. This flaw allows remote exploitation without requiring authentication or user interaction, making it highly accessible to attackers. The CVSS 4.0 score is 6.9 (medium severity) with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact includes partial loss of confidentiality, integrity, and availability of the system's data. While no known exploits are currently observed in the wild, a public exploit has been published, increasing the risk of exploitation. The vulnerability does not require authentication, which broadens the attack surface. The lack of a patch link indicates that a fix may not yet be available, emphasizing the need for immediate mitigation measures. Given the nature of the system, exploitation could lead to unauthorized access to sensitive health data, data manipulation, or disruption of health monitoring operations, which are critical during a pandemic response.

For European organizations, especially healthcare providers, public health authorities, and institutions involved in COVID-19 monitoring and response, this vulnerability poses significant risks. Unauthorized access or manipulation of health data can lead to privacy breaches violating GDPR regulations, legal liabilities, and loss of public trust. Disruption of health monitoring systems could impair timely response to COVID-19 outbreaks, affecting public health outcomes. The medium severity score reflects the potential for moderate damage, but the ease of remote exploitation without authentication elevates the threat level. Organizations relying on this specific E-Logbook system or similar platforms could face data integrity issues, unauthorized data disclosure, and potential service outages. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within healthcare networks, which are often interconnected with other critical infrastructure.

Immediate mitigation should include implementing input validation and parameterized queries or prepared statements to prevent SQL injection in the /check_profile.php script, specifically sanitizing the 'profile_id' parameter. If a vendor patch is not yet available, organizations should consider deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this endpoint. Network segmentation and strict access controls should be enforced to limit exposure of the vulnerable system to untrusted networks. Continuous monitoring and logging of access to /check_profile.php should be enabled to detect suspicious activity. Organizations should also conduct code reviews and penetration testing focused on injection flaws in their health monitoring applications. Finally, given the sensitivity of the data, encrypting stored data and ensuring robust backup procedures will help mitigate data integrity and availability risks in case of exploitation.
