Description

Jointelli 5G CPE 21H01 firmware JY_21H01_A3_v1.36 devices allow (blind) OS command injection. Multiple endpoints are vulnerable, including /ubus/?flag=set_WPS_pin and /ubus/?flag=netAppStar1 and /ubus/?flag=set_wifi_cfgs. This allows an authenticated attacker to execute arbitrary OS commands with root privileges via crafted inputs to the SSID, WPS, Traceroute, and Ping fields.
