CWE-912 HIDDEN FUNCTIONALITY:
The "update" binary in the firmware of the affected product sends attempts to mount to a hard-coded, routable IP address, bypassing existing device network settings to do so. The function triggers if the 'C' button is pressed at a specific time during the boot process. If an attacker is able to control or impersonate this IP address, they could upload and overwrite files on the device.
Per FDA recommendation, CISA recommends users remove any Contec CMS8000 devices from their networks.
If asset owners cannot remove the devices from their networks, users should block 202.114.4.0/24 from their networks, or block 202.114.4.119 and 202.114.4.120.
Please note that this device may be re-labeled and sold by resellers.

CWE-295 IMPROPER CERTIFICATE VALIDATION:
The affected product is vulnerable due to failure of the update mechanism to verify the update server's certificate which could allow an attacker to alter network traffic and carry out a machine-in-the-middle attack (MITM). An attacker could modify the server's response and deliver a malicious update to the user.
Medixant recommends users download the v2025.1 or later version of their software.
