This signature detects attempts to exploit a known vulnerability against SCADA Modbus Tri device. A successful attack can lead to denial of service.
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.
