## What is CVE-2025-0626?

CVE-2025-0626 is a high-severity vulnerability in Contec Health CMS8000 Patient Monitor, published on 30 Jan 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### 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.

Weakness: CWE-912 (Hidden Functionality)
