A command injection vulnerability exists in the ToToLink A720R Router firmware V4.1.5cu.614_B20230630 within the cloudupdate_check binary, specifically in the sub_402414 function that handles cloud update parameters. User-supplied 'magicid' and 'url' values are directly concatenated into shell commands and executed via system() without any sanitization or escaping. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device.
