CVE-2023-24582Network attack vector

Arbitrary command execution via unsanitized JSON name

Published Jul 6, 2023 · Updated Nov 4, 2025

OS command injection in Milesight UR32L 32.3.0.5 allows remote attackers to execute arbitrary commands through a crafted TCP JSON request. The urvpn_client execute_urvpn_command path passes the JSON name value to cmd_name_action, which embeds it in a shell command executed by system() without validation. The Milesight VPN client must be running and reachable; successful injection executes commands with the client's operating privileges.
