luci-proto-openvpn through 0.11.1, fixed in commit e4ff45e, contains a command injection vulnerability in the generateKey ubus method where the cl_meta parameter is interpolated into a shell command without proper escaping or quoting. An authenticated LuCI user with OpenVPN protocol configuration access can inject arbitrary shell metacharacters into cl_meta to execute commands as root via the popen function.
