Unauthenticated command execution via unfiltered MQTT parameter
Published Feb 3, 2023 · Updated Mar 26, 2025
Command injection in TOTOLINK T8 4.1.5cu allows remote attackers to execute arbitrary commands through a crafted MQTT packet. The meshSlaveDlfw handler fails to filter the serverIp value received through its MQTT topic before using it in an operating-system command. The router's MQTT service must be network-reachable; no authentication or user interaction is required, and exploitation compromises the device.
