CVE-2025-43978Network attack vector

Root command execution via unvalidated ubus fields

Published Aug 5, 2025 · Updated Aug 5, 2025

OS command injection in Jointelli 5G CPE 21H01 firmware JY_21H01_A3_v1.36 allows remote authenticated users to execute commands. The set_WPS_pin, netAppStar1, and set_wifi_cfg ubus handlers pass crafted SSID, WPS, Traceroute, or Ping field values to OS commands without proper validation. Access to the management interface and a valid authenticated session are required; injected commands run with root privileges.
