CVE-2025-30060 is a medium-severity SQL Injection vulnerability identified in the CGM CLININET product, specifically within the ReturnUserUnitsXML.pl service's "getUserInfo" function. The vulnerability arises due to improper neutralization of special elements in SQL commands (CWE-89), allowing an attacker to inject malicious SQL code through the "UserID" parameter. This flaw enables an attacker with low privileges (PR:L) and no user interaction (UI:N) to remotely exploit the vulnerability over an adjacent network (AV:A), such as within the same organizational network or VPN. The vulnerability does not require authentication tokens (AT:N) but does require some level of privilege, indicating that the attacker must have limited access to the system or network. Exploitation could lead to high confidentiality impact (VC:H), potentially exposing sensitive user data, but does not affect integrity or availability. The vulnerability is present in version 0 of CGM CLININET, a clinical information system used in healthcare environments. No patches or known exploits in the wild have been reported as of the publication date. The CVSS 4.0 vector indicates that the attack surface is limited to adjacent networks, and the attack complexity is low, making exploitation feasible in environments where the attacker can access the network segment hosting the vulnerable service. The lack of required user interaction and the high confidentiality impact make this vulnerability significant for protecting patient data and complying with healthcare data protection regulations.

For European organizations, particularly healthcare providers using CGM CLININET, this vulnerability poses a significant risk to patient data confidentiality. Exploitation could lead to unauthorized disclosure of sensitive medical records, violating GDPR and other data protection laws, potentially resulting in legal penalties and reputational damage. The medium severity rating reflects that while the vulnerability does not directly impact system availability or data integrity, the exposure of confidential information could undermine trust in healthcare services and disrupt clinical workflows if exploited. Additionally, healthcare environments often have interconnected systems, so an attacker leveraging this vulnerability could use it as a foothold for further lateral movement or reconnaissance within the network. Given the critical nature of healthcare data and the increasing targeting of healthcare infrastructure by cyber adversaries, this vulnerability demands prompt attention to prevent data breaches and maintain compliance with European data protection standards.

To mitigate CVE-2025-30060 effectively, European healthcare organizations should: 1) Implement strict input validation and parameterized queries or prepared statements in the ReturnUserUnitsXML.pl service to neutralize SQL injection vectors, specifically sanitizing the "UserID" parameter. 2) Restrict network access to the vulnerable service by segmenting the network and applying firewall rules to limit access to trusted hosts and users only, reducing the attack surface from adjacent networks. 3) Conduct thorough code reviews and security testing of CGM CLININET deployments to identify and remediate similar injection flaws proactively. 4) Monitor logs for unusual database query patterns or failed injection attempts to detect potential exploitation attempts early. 5) Engage with the vendor CGM for official patches or updates and apply them promptly once available. 6) Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the vulnerable parameter. 7) Train IT and security staff on secure coding practices and the importance of patch management in healthcare IT environments. These targeted actions go beyond generic advice by focusing on the specific vulnerable component, network access controls, and proactive detection tailored to the CGM CLININET context.
