A brand new set of essential vulnerabilities has been recognized in Contec Well being’s CMS8000 Affected person Monitor, posing vital cybersecurity and affected person security dangers. These vulnerabilities, which have obtained a CVSS v4 base rating of 9.3, permit for distant exploitation with low assault complexity. The safety points recognized embrace an Out-of-Bounds Write vulnerability, a Hidden Performance (Backdoor), and Privateness Leakage. These flaws might result in distant code execution, unauthorized file uploads, and publicity of delicate affected person data.
Each the Cybersecurity and Infrastructure Security Agency (CISA) and the Meals and Drug Administration (FDA) have issued security communications addressing these dangers, highlighting the potential for large-scale exploitation in healthcare environments.
Background
- Crucial Infrastructure Sector: Healthcare and Public Well being
- World Deployment: The CMS8000 Affected person Monitor is used worldwide.
- Producer: Contec Well being, headquartered in China.
- Researcher: An nameless security researcher reported these vulnerabilities to CISA.
Danger Analysis
Profitable exploitation of these vulnerabilities can allow a malicious actor to remotely ship specifically crafted UDP requests, permitting them to write down arbitrary information. This might lead to remote code execution, unauthorized entry to affected person info, and even the flexibility to control gadget performance. Furthermore, the gadget has been discovered to leak affected person and sensor information to an unknown exterior community, additional exacerbating safety issues.
A very side of those vulnerabilities is that simultaneous exploitation of all affected units inside a shared community is feasible. This will increase the risk of coordinated cyberattacks that would compromise a number of affected person screens in a single healthcare facility.
To mitigate these dangers, each the FDA and CISA have launched pointers and reality sheets detailing the vulnerabilities and beneficial safety measures.
Technical Particulars
Affected Merchandise
The vulnerabilities have an effect on the next firmware variations of the CMS8000 Affected person Monitor:
- smart3250-2.6.27-wlan2.1.7.cramfs
- CMS7.820.075.08/0.74(0.75)
- CMS7.820.120.01/0.93(0.95)
- All firmware variations (CVE-2025-0626, CVE-2025-0683)
Vulnerabilities Overview
1. Out-of-Bounds Write (CWE-787)
- CVE-2024-12248
- Permits an attacker to ship specifically formatted UDP requests that write arbitrary information, probably resulting in distant code execution.
- CVSS v3.1 Base Rating: 9.8
- CVSS v4 Base Rating: 9.3
2. Hidden Performance (Backdoor) (CWE-912)
- CVE-2025-0626
- The gadget sends remote access requests to a hard-coded IP deal with, bypassing community settings. This might permit unauthorized actors to add and overwrite recordsdata on the monitor.
- CVSS v3.1 Base Rating: 7.5
- CVSS v4 Base Rating: 7.7
3. Privacy Leakage (CWE-359)
- CVE-2025-0683
- In default configuration, the monitor transmits plain-text affected person information to a hard-coded public IP deal with, resulting in potential publicity of confidential info.
- CVSS v3.1 Base Rating: 5.9
- CVSS v4 Base Rating: 8.2
Mitigation Measures
Given the excessive severity of those vulnerabilities, the FDA and CISA strongly suggest eradicating affected CMS8000 Affected person Screens from networks till a safe patch is accessible. Moreover, organizations ought to implement the next safety measures:
- Prohibit Community Publicity: Guarantee all medical units, together with affected person screens, aren’t accessible from the internet.
- Use Firewalls: Place affected units behind firewalls and isolate them from enterprise networks.
- Replace Firewall Guidelines: Block unauthorized entry to affected units and exterior communication with unknown IP addresses.
- Subnet Segmentation: Guarantee medical units are positioned on a separate, low-privilege community section.
- Supply Tools from Trusted Producers: Keep away from utilizing rebranded or resold variations of the CMS8000 which will nonetheless comprise vulnerabilities.
CISA CSAF Repository & OASIS CSAF 2.0 Normal
To boost safety automation and expedite mitigation efforts, CISA has made accessible safety advisories in machine-readable format by way of its CSAF repository. This repository follows the OASIS CSAF 2.0 customary, permitting organizations to eat advisories in a structured method and scale back response instances.
The OASIS CSAF Technical Committee developed CSAF as a standardized method for sharing safety advisories in a machine-readable format, facilitating sooner remediation and bettering total cybersecurity resilience. Distributors and cybersecurity professionals are inspired to leverage this useful resource to remain up to date on safety threats and vulnerabilities.
Healthcare organizations should act swiftly to mitigate these dangers by eradicating affected units from their networks, implementing strict entry controls, and leveraging cybersecurity finest practices. Moreover, producers should prioritize safety updates and make sure the security of essential medical units.
CISA and the FDA will proceed to watch the scenario and supply up to date safety suggestions as needed. Organizations are inspired to remain vigilant and proactive in securing their medical infrastructure towards rising cyber threats.
