Researchers from Claroty this week disclosed multiple critical vulnerabilities in vendor implementations of the Open Platform Communications (OPC) network protocol that is widely used in operational technology (OT) networks. The flaws affect products from three vendors whose technologies are also being used as third-party components in multiple other white-label products running the OPC protocol. Vulnerabilities expose organizations using the vulnerable products to distributed denial-of-service attacks, remote code execution, and leaks and theft of sensitive data.”]
