Triangle Research International (aka Tri) Nano-10 PLC devices with firmware before r81 use an incorrect algorithm for bounds checking of data in Modbus/TCP packets, which allows remote attackers to cause a denial of service (networking outage) via a crafted packet to TCP port 502.

Security readout for executives and security teams

This CVE affects Triangle Research International Nano-10 PLCs running firmware before r81. A malformed Modbus/TCP packet can cause a networking outage, disrupting PLC communications. The public record describes denial of service, not data theft or code execution. Exposure is most likely where TRI Nano-10 PLCs with firmware before r81 are reachable over Modbus/TCP, especially from less-trusted plant, vendor, or enterprise network segments. Treat this as an operational resilience issue. Prioritize sites where affected PLCs control important processes or where Modbus/TCP is reachable beyond tightly controlled industrial networks. Mitigation focus: Identify TRI Nano-10 PLCs and confirm firmware versions.; Review vendor or CISA guidance before applying firmware r81 or later.; Restrict Modbus/TCP TCP/502 access to trusted control networks only..
