Cudy TR3000 before 2.5.42 contains an OS command injection vulnerability that allows a malicious or compromised ACS to execute commands as root by supplying an unvalidated InternetGatewayDevice.User.{i}.Username value. Attackers can send a SetParameterValues request with shell metacharacters that set_UserUsername() in obuspa_system.lua passes to os.execute(), gaining root command execution.
