Technical details
This is an OS command injection vulnerability in the SystemAsh function of Apis/system.c in the Kylin component. The vulnerability exists because user-supplied input to the AlarmVoiceURL argument is not properly sanitized before being passed to system command execution. An unauthenticated remote attacker can exploit this over the network to execute arbitrary operating system commands with device privileges, achieving full system compromise.
