Description
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 a crafted InternetGatewayDevice.User.{i}.Password value. Attackers can send a SetParameterValues request with shell metacharacters that obuspa_system.lua concatenates into a luci.util.exec() command string, gaining root command execution.
