Description
Cudy TR3000 before 2.5.42 contains a mass assignment vulnerability in the vpn.set_conf App RPC method that allows authenticated administrators to inject arbitrary OpenVPN server options. Attackers can set enabled=1 and a malicious up option in the openvpns object, which the openvpn-hotplug wrapper executes via /bin/sh as root.
