Triangle Research International (aka Tri) Nano-10 PLC devices with firmware r81 and earlier do not properly handle large length values in MODBUS data, which allows remote attackers to cause a denial of service (transition to the interrupt state) via a crafted packet to TCP port 502.

Security readout for executives and security teams

Triangle Research International Nano-10 PLC firmware r81 and earlier can be forced into an interrupt state by malformed Modbus data. For operators, this is a denial-of-service risk: affected automation could stop or require recovery, especially if Modbus TCP is reachable from untrusted networks. Exposure is most likely where TRI Nano-10 PLCs running firmware r81 or earlier are still deployed and reachable over Modbus TCP. Risk increases with internet exposure, flat IT/OT routing, vendor remote access, or weak firewall rules around TCP/502. Prioritize if Nano-10 PLCs support safety, production, or facility operations and are reachable over routable networks. If no affected devices are present, track as historical ICS risk and close with inventory evidence. Mitigation focus: Identify all TRI Nano-10 PLCs and record firmware versions.; Check TRI or vendor guidance for firmware newer than r81 or approved compensating controls.; Restrict TCP/502 access to trusted engineering stations and required control peers..
