CGM CLININET server: network attackers can run commands as root

A medical records server accepts messages from other hospital systems, and its message handlers run with full administrator power. An attacker on the same network could send a crafted message and take complete control of the server.

How the attack works simplified

  1. 1Attacker on networkHas access to the same network segment
  2. 2Crafted HL7 messageSent to the HL7 communication port
  3. 3HL7 process parses itUntrusted data handled by the process
  4. 4Code runs as rootProcess runs with root privileges
  5. ResultAttacker controls the server

What happened

Multiple HL7 communication processes in the CGM CLININET application server run with root privileges while parsing untrusted input from external systems, enabling remote code execution as root by an adjacent-network attacker.

Why it is dangerous: Full control of the server would expose or alter patient data and could disrupt clinical systems. Healthcare organizations running CLININET are at risk.

Are you affected?

You are affected if you run CGM CLININET application server up to version 2026.MS3 (later versions may also be vulnerable) with HL7 communication interfaces reachable from your network.

CGM CLININET application server, versions up to and including 2026.MS3; later versions may also be vulnerable.

What to do

  1. Check whether your CGM CLININET version is 2026.MS3 or earlier, or whether you cannot confirm it is newer
  2. Restrict network access to the HL7 interfaces so only the systems that need them can connect
  3. Contact CGM for a patch or official mitigation and apply it as soon as it is available
  4. Monitor HL7 traffic and server logs for unexpected connections or processes
