Notes
CISA Disclaimer

Summary
Armis researchers Gregory Vishnepolsky, Dor Zusman, and Ben Seri, reported these vulnerabilities to CISA.
Disclaimer
CISA is aware of a public report detailing vulnerabilities found in the Interpeak IPnet TCP/IP stack. The Interpeak IPnet stack vulnerabilities were first reported under ICSA-19-211-01 Wind River VxWorks. These vulnerabilities have expanded beyond the affected VxWorks systems and affect additional real-time operating systems (RTOS). CISA has reached out to affected vendors of the report and asked them to confirm the vulnerabilities and identify mitigations. CISA is issuing this advisory to provide early notice of the reported vulnerabilities and identify baseline mitigations for reducing risks to these and other cybersecurity attacks.
ENEA Mitigation Note
Enea has no IPNet customers on support contract in the United States.
Green Hills Software Mitigation Note
Green Hills Software has proactively informed affected users and offers consulting services to implement mitigations.
Microsoft Mitigation Note
Microsoft states they have no history of support or integration work to include IPnet and have not released a version of ThreadX bundled with IPnet. Microsoft does caution that some hardware makers could have used ThreadX and a custom set IPnet in the hardware.
TRON Mitigation Note
TRON Forum reports they only publish the specification for ITRON RTOS. Various implementations are used by many users world-wide and are created by various implementors (some commercial, and some academic and some government) according the specification document. TRON Forum, the caretaker of the ITRON specification, has not endorsed the use of any particular TCP/IP stack including one from Interpeak. The choice of TCP/IP stack is up to the RTOS vendor and application developers, and thus each application user needs to check whether TCP/IP stack developed by Interpeak is used inside their application. TRON Forum will send out a preliminary warning to members by mailing list to notify implementors of the reported vulnerabilities.
ZebOS Mitigation Note
ZebOS by IP Infusion has not yet responded to CISA inquiries.
