The CVE-2025-0626 vulnerability affects the Contec Health CMS8000 Patient Monitor, where the "monitor" binary in the firmware attempts to connect to a hard-coded, routable IP address. This action bypasses the existing device network settings, potentially enabling unauthorized access to the device. The vulnerability has a CVSS score of 7.7, classifying it as high severity, which underscores its serious implications for device integrity and confidentiality.
Risk to organizations includes the possibility of malicious actors exploiting this vulnerability to upload and overwrite files, effectively creating a backdoor into the device. The function is triggered during device updates initiated from the user menu, making it a critical area of concern for device administrators.
With the current status of 'Awaiting Analysis', organizations must remain vigilant as this vulnerability presents a significant risk. Organizations should prioritize patching immediately to mitigate potential exploitation.
This vulnerability can potentially lead to severe impacts on patient safety and confidentiality, given the critical nature of the devices involved.
Vulnerability Details
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. This vulnerability has been classified under CWE-912, indicating an issue with a lack of proper validation in the network settings.
The CVSS score of 7.7 signifies a high severity, with an attack vector categorized as NETWORK. The potential consequences include high confidentiality, integrity, and availability impacts, making this a critical vulnerability for organizations relying on such devices.
Technical Analysis
The root cause of this vulnerability lies in the firmware's design, which allows the monitor binary to connect to a predetermined IP without proper checks. The attack vector is network-based, requiring low complexity for exploitation, with no privileges required from the user. User interaction is only passive, meaning an attacker could exploit this without the user initiating any action.
Confidentiality, integrity, and availability impacts are all rated as high, highlighting the potential for significant disruption and compromise of sensitive information.
Risk & Impact Analysis
The real-world deployment risk of CVE-2025-0626 is substantial, particularly in healthcare environments where patient monitors are critical. An attacker exploiting this vulnerability could gain unauthorized access to patient data and potentially manipulate device functionality, leading to dire consequences.
Organizations should address this vulnerability in their priority patch cycle to mitigate the associated risks. The potential blast radius is significant, as affected devices are commonly used in sensitive healthcare settings, underscoring the urgency for immediate action.
