Redmi router RB03 v1.0.57 is vulnerable to forged ICMP redirect message attacks. An attacker in the same WLAN as the victim can hijack the traffic between the victim and any remote server by sending out forged ICMP redirect messages.
The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.
