Overview
Recently, a security expert from IBM X-Force discovered a remote code execution vulnerability (CVE-2019-7406) in multiple models of TP-Link Wi-Fi extenders. This vulnerability can be exploited by unauthenticated, remote attackers by sending a malformed HTTP request so as to execute arbitrary shell commands on a target Wi-Fi extender. The attack does not require escalation of privileges as all processes on the vulnerable devices already run with root privileges.
The models of TP-Link Wi-Fi extenders affected by this vulnerability include RE365, RE650, RE350, and RE500.
