CVE-2025-30062 is an SQL injection vulnerability classified under CWE-89, affecting the CGM CLININET product, a healthcare software solution. The flaw exists in the CheckUnitCodeAndKey.pl service, specifically in the validateOrgUnit function, where user-supplied input is improperly sanitized before being incorporated into SQL commands. This improper neutralization of special elements in SQL queries allows an attacker to inject arbitrary SQL code. The vulnerability has a CVSS 4.0 score of 6.9, indicating medium severity, with an attack vector requiring adjacent network access (AV:A), low attack complexity (AC:L), no privileges required (PR:L), and no user interaction (UI:N). The vulnerability impacts confidentiality (VC:H) but not integrity or availability. Exploiting this flaw could enable attackers to extract sensitive data, such as patient records or organizational information, from the backend database or potentially alter data if further chained with other vulnerabilities. No patches or known exploits are currently available, and the affected version is listed as '0', suggesting early or initial releases. The vulnerability was reserved in March 2025 and published in March 2026 by CERT-PL. Given the product's healthcare context, the risk to sensitive personal health information is significant. The lack of required user interaction and low privileges needed for exploitation increase the threat's feasibility within local or network-adjacent environments.

The primary impact of CVE-2025-30062 is unauthorized access to sensitive healthcare data stored within CGM CLININET systems. Attackers exploiting this SQL injection could retrieve confidential patient information, organizational data, or system configuration details, leading to privacy violations and potential regulatory non-compliance (e.g., GDPR, HIPAA). Although the vulnerability does not directly affect system integrity or availability, data disclosure alone can have severe consequences, including identity theft, fraud, and reputational damage. Healthcare organizations relying on CGM CLININET may face operational disruptions if attackers leverage the vulnerability to gain deeper access or pivot to other systems. The medium severity score reflects the balance between the potential data exposure and the limited attack vector (adjacent network access) and privileges required. However, given the critical nature of healthcare data, the impact on patient safety and trust can be substantial. The absence of known exploits reduces immediate risk but underscores the need for proactive mitigation.

To mitigate CVE-2025-30062, organizations should implement the following specific measures: 1) Apply vendor patches promptly once released; currently, no patch is available, so monitor vendor advisories closely. 2) Conduct a thorough code review of the CheckUnitCodeAndKey.pl service and the validateOrgUnit function to identify and remediate unsafe SQL query constructions. 3) Refactor vulnerable code to use parameterized queries or prepared statements, eliminating direct concatenation of user input into SQL commands. 4) Implement strict input validation and sanitization routines to reject or neutralize malicious input before processing. 5) Restrict network access to the affected service, limiting it to trusted hosts and networks to reduce the attack surface. 6) Employ database activity monitoring and anomaly detection to identify suspicious query patterns indicative of SQL injection attempts. 7) Harden the database user permissions to follow the principle of least privilege, minimizing the potential damage from successful exploitation. 8) Educate developers and security teams on secure coding practices related to SQL injection prevention. 9) Regularly perform penetration testing and vulnerability scanning focused on injection flaws in healthcare applications. These targeted actions go beyond generic advice by focusing on the specific vulnerable function and the operational context of CGM CLININET.
