CISA has released a notice urging administrators to apply updates to a variety of industrial control systems after discovering vulnerabilities in multiple open-source and proprietary Object Management Group (OMG) Data-Distribution Service (DDS) implementations.
The equipment containing the vulnerabilities includes CycloneDDS, FastDDS, GurumDDS, OpenDDS, Connext DDS Professional, Connext DDS Secure, Connext DDS Micro, and CoreDX DDS.
“Successful exploitation of these vulnerabilities could result in denial-of-service or buffer-overflow conditions, which may lead to remote code execution or information exposure,” CISA explained.
They provided links to each company’s patches or fixes for the issue, but they noted that GurumNetworks did not respond to their messages. CISA said organizations using GurumNetworks’ tools should contact them directly.
Dr. Dennis Hackney, head of industrial cybersecurity services development at ABS Group, told ZDNet that many industrial control system owners don’t realize that their systems are full of open-source software, much like OpenDDS.
“The reasons for this are multifaceted but often stem from the proprietary and tailored nature of each control system. OEMs and engineers develop solutions that are as functional as possible without adding unnecessary costs. Be
