CVE-2013-2793: Triangle MicroWorks SCADA Data Gateway 2.50.0309 through 3.00.0616, DNP3 .NET Protocol components 3.06.0.17...

Security readout for executives and security teams

This CVE affects Triangle MicroWorks SCADA Data Gateway and DNP3 protocol components used in industrial environments. A specially crafted DNP3 TCP packet can make affected software enter an infinite loop, causing denial of service. The main business concern is loss of availability for systems that depend on these components. Exposure is most likely in OT or SCADA environments using the listed Triangle MicroWorks Data Gateway or DNP3 libraries, especially where DNP3 over TCP is reachable from operational networks or poorly segmented paths. Prioritize this where Triangle MicroWorks DNP3 software supports critical operations. The issue is availability-focused, not data theft, but denial of service in SCADA environments can still disrupt monitoring or control workflows. Mitigation focus: Inventory Triangle MicroWorks SCADA Data Gateway and DNP3 component versions.; Check Triangle MicroWorks and CISA advisory guidance for fixed versions or vendor mitigations.; Restrict DNP3 TCP access to trusted management and operational hosts only..
