Trianglemicroworks

Trianglemicroworks develops supervisory control and data acquisition (SCADA) components and industrial communications libraries, including DNP3 and IEC 60870-5 protocol implementations and gateway products, that operate in critical infrastructure and utility networks. While the vendor's product portfolio is narrow, its libraries and protocol stacks achieve broad deployment as embedded components across industrial control systems and third-party integrations, placing it among the more prominent vendors in critical-infrastructure vulnerability tracking. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity, and recur through weakness classes including path traversal, missing authentication, improper input validation, memory-bounds violations, and out-of-bounds writes that reflect both the protocol-parsing complexity and the operational-technology deployment context of SCADA components. Defenders should prioritize inventory and patching of affected SCADA gateways and systems that incorporate this vendor's protocol libraries, as flaws in industrial communication stacks can threaten availability and integrity of grid and utility operations. Current exploitation activity and exposure counts are shown alongside this summary.
