CVE-2025-48466 is an unauthenticated remote vulnerability in a device exposing Modbus TCP functionality. According to the provided description, a remote attacker can send crafted Modbus TCP packets to manipulate Digital Outputs, including remote control of a relay channel. This indicates that the affected device accepts security-sensitive control commands over Modbus TCP without adequate authentication or access restriction. The issue can enable unauthorized state changes in physical outputs and associated relay-controlled processes, creating operational and potential safety consequences in industrial environments.

This repository contains a proof-of-concept exploit for CVE-2025-48466, targeting the Advantech WISE-4060/LAN IoT Gateway. The exploit consists of a single Python script (main.py) that uses the Scapy library and raw sockets to craft and send Modbus TCP packets to the target device on port 502. The script fuzzes the address range for Digital Output (DO) channels, attempting to manipulate their state (specifically, to turn them OFF) without authentication. The README provides context about the vulnerability, its impact, and usage instructions. The exploit demonstrates that an unauthenticated attacker on the network can remotely control critical outputs (such as door relays) on the device, potentially leading to safety hazards or operational disruptions. The only fingerprintable endpoint is the Modbus TCP service (IP:502) on the target device.
