Technical details

The vulnerability is an OS command injection flaw in the Net Check feature accessible via the /setting endpoint. The cmdPing Socket.io event fails to properly sanitize user-supplied input before passing it to the underlying operating system shell. An unauthenticated network attacker can exploit this by sending a crafted request containing shell metacharacters to execute arbitrary commands with root privileges. The attack requires network reachability to the affected device but no authentication or user interaction.
