A remote OS command injection exists in the WireGuard component. The issue occurs within the `wireguard cli group` handler of the `/protocol.csp` file. An attacker can exploit this by manipulating the `group id` or `group name` variables, which are passed unsanitized to a shell command via the `system()` function. Successful exploitation allows the execution of operating system commands with router-service privileges. Access to the management endpoint and a session token are required for exploitation.
