The U.S. Cybersecurity and Infrastructure Security Agency (CISA) said it is aware of vulnerabilities affecting Treck IP stack implications for embedded systems.
Known as Ripple20, the vulnerabilities allow a remote attacker to exploit and take control of an affected system, according to the CISA statement.
Among the affected companies were B. Braun, Baxter (NYSE:BAX), Green Hills Software and CareStream. CISA encouraged affected users and administrators to review the affected products for additional information and mitigations, as well as to update to the latest stable version of the Treck IP stack software.
B. Braun issued a statement saying that it is aware of the notification from CISA, sharing that the vulnerabilities exist in the third-party software used for network communication in its Outlook 400ES safety infusion pump system.
The company said it received 24 patches from Treck to resolve vulnerabilities, determining that 20 patches are not applicable to the Outlook 400 ES platform. It is not advising any customer action at this time.
Five versions of the Baxter Spectrum infusion system’s wireless battery modules are impacted by the reported vulnerabilities, according to a company statement. To date, the company has not received reports of impacted clinical use related to the vulnerabilities, while it also received a patch and is taking the necessary steps to mitigate any issues.
Additionally, Baxter said to isolate the Spectrum infusion systems to its own network in an effort to reduce the probability that a threat actor could execute an adjacent attack against the system. Additionally, the company recommended appropriate wireless network security protocols and, as a last resort, customers may disable the wireless operation of the pump.
Green Hills said in a statement that its GHnet v2 network stack is based on the network stack from Treck, although they are not identical. Green Hills added new features and fixed bugs, citing those advancements as a reason the vulnerabilities’ impact is less severe than it could have been.
Its Integrity real-time operating system will include fixes for vulnerabilities in future releases and Green Hills is also making patches available to customers on previous releases.
No additional information for the affected products at CareStream was provided, and the company is yet to release a written statement on the matter.
