CVE-2025-1204: Contec Health CMS8000 Patient Monitor

High severity, CVSS 7.7. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
