GE Medical Devices Vulnerability
ICSA： ICS Advisory (ICSMA-18-037-02)
This advisory was originally posted to the HSIN ICS-CERT library on February 6, 2018, and is being released to the NCCIC/ICS-CERT website.
Independent researcher Scott Erven submitted information regarding the potential use of default or hard-coded credentials in multiple GE Healthcare products. Following the researcher’s report, GE performed a self-assessment and validated that multiple GE Healthcare products use default or hard-coded credentials. GE has reviewed capability to change passwords identified by the researcher within the product documentation, and users are advised to contact GE Service for assistance in changing passwords.
Vulnerability information about the affected products is publicly available.

Successful exploitation of this vulnerability may allow a remote attacker to bypass authentication and gain access to the affected devices.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC recommends that organizations evaluate the impact of this vulnerability based on their operational environment and specific clinical usage.
GE Healthcare is a U.S.-based company that maintains offices in several countries around the world.
According to GE, the affected products are deployed across the Healthcare and Public Health sector. GE estimates that most of these products are used worldwide; however, the Optima 680, the Image Vault 3.x, and the THUNIS-800+ have very limited or no usage in the United States or Canada.
The affected devices use default or hard-coded credentials.

This vulnerability could be exploited remotely.
EXISTENCE OF EXPLOIT
Vulnerability information about the affected products is publicly available.
An attacker with a low skill level would be able to exploit this vulnerability.
GE has produced product updates that are available upon request, which replace default or hard-coded credentials with custom credentials for all but three of the affected products. GE’s product updates are not available for the Optima 680, Revolution XQ/i, and THUNIS-800+ systems.
NCCIC recommends that users take additional defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
- Close all unused ports on affected systems.
- Where possible, discontinue or limit the use of non-product-related third-party software, such as email and web browser software on the affected system, which could broaden the attack surface of medical devices.
- Ensure that affected systems have applied the most current vendor-issued patches available.
- Restrict network access to affected systems and ensure they are not directly accessible from the Internet.
- Follow good network design practices, such as implementing network segmentation, and use DMZs with properly configured firewalls to selectively control, and monitor all traffic passed between zones and systems.
- Monitor and log all network traffic attempting to reach affected products for suspicious activity.
- When remote access is required, use secure methods such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.

NCCIC also provides a section for control systems security recommended practices on the ICS-CERT web page. NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Additional mitigation guidance and recommended practices are publicly available in the NCCIC Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT website.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
