CVE-2025-30046 in CLININET
Summary
by MITRE • 10/23/2026
In the CGM CLININET application server, multiple processes responsible for HL7 communication with external systems run with root privileges while processing untrusted data received from those external systems. An attacker in adjacent network able to send data to these HL7 communication processes can achieve remote code execution with root privileges.
The vulnerability was confirmed to affect versions up to 2026.MS3 but later versions may also be vulnerable.

The Common Ground Care Management CLININET application server contains a critical security flaw within its HL7 communication subsystem that allows for remote code execution with elevated privileges. This vulnerability stems from the architectural decision to run multiple processes responsible for handling Health Level Seven (HL7) messages with root-level permissions rather than utilizing least-privilege principles. These specific processes are designed to interface with external healthcare systems, receiving and processing untrusted data streams originating from those third-party sources. Because HL7 is a standard protocol used extensively in electronic health record exchanges, it often traverses network boundaries that may not be fully secured against sophisticated attackers or compromised internal nodes.
The core technical flaw lies in the privilege escalation inherent to these processes. When an attacker positioned on an adjacent network segment sends maliciously crafted data payloads to the HL7 endpoints, the application server accepts this input and passes it directly to the root-privileged handlers for processing. Since the software fails to adequately sanitize or validate the incoming untrusted data before execution within a privileged context, specific injection techniques can be employed to execute arbitrary commands on the underlying operating system. This results in remote code execution where the attacker gains full administrative control over the server hosting CLININET. The ability to operate with root privileges significantly amplifies the severity of this vulnerability, as it allows for complete compromise of the host environment, including access to sensitive patient data stored locally and potential pivoting into other internal network segments.
From a classification perspective, this issue aligns closely with CWE-78 Improper Neutralization of Special Elements used in an OS Command, commonly known as OS command injection. The failure to restrict process privileges corresponds to CWE-250 Execution with Unnecessary Privileges, which violates the principle of least privilege and increases the blast radius of any successful exploitation attempt. In terms of adversary behavior, this vulnerability facilitates initial access through network-based attacks followed by privilege escalation techniques documented in the MITRE ATT&CK framework under T1068 Exploitation for Privilege Escalation and potentially T1190 Exploit Public-Facing Application if the HL7 interface is exposed to untrusted networks. The operational impact includes potential unauthorized access to protected health information, manipulation of clinical data integrity, and complete loss of confidentiality, integrity, and availability for systems dependent on CLININET services.
Mitigation strategies must prioritize immediate remediation through software updates provided by Common Ground Care Management, specifically targeting versions up to 2026.MS3 or later if patches are available. However, given the note that later versions may also be vulnerable, organizations should verify their specific build numbers against vendor advisories and apply all relevant security patches promptly. In addition to patching, network segmentation is critical; HL7 interfaces communicating with external systems should be isolated within a dedicated demilitarized zone or restricted subnet to prevent adjacent network attackers from reaching these endpoints. Implementing strict input validation at the application layer, although secondary to fixing the code itself, can provide defense-in-depth by filtering out malformed messages before they reach privileged handlers. Furthermore, auditing and monitoring for unusual outbound connections or command executions originating from the CLININET server processes will aid in detecting exploitation attempts during any window of exposure prior to full remediation.
