CVE-2025-30052 · Severity: info · Published 2026-10-23

CGM CLININET is a hospital information system used to manage patient data and clinical workflows. The rsyncd service in this system grants file access based solely on the client's source IP address, allowing an attacker who can spoof a trusted IP to bypass authentication and modify critical files on the hospital's server without proper credentials.

## Technical details

The rsyncd service implements authentication using only IP address whitelisting without proper cryptographic authentication mechanisms. An attacker on an adjacent network able to spoof IP packets can impersonate an allowed client, gaining unauthorized access to edit files on the system with the privileges of the rsyncd process. No fix is stated in the advisory.
