CVE-2025-0626Hidden Functionality vulnerability in Contec Health CMS8000 Patient Monitor
High 7.5
In plain English
A high-severity security flaw in CMS8000 Patient Monitor from Contec Health. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.1% (higher than 67% of all known vulnerabilities).
Official description
The "monitor" binary in the firmware of the affected product attempts to mount to a hard-coded, routable IP address, bypassing existing device network settings to do so. The function also enables the network interface of the device if it is disabled. The function is triggered by attempting to update the device from the user menu. This could serve as a backdoor to the device, and could lead to a malicious actor being able to upload and overwrite files on the device.
