Estado: ModificadaCrítica (9.8)—

Verizon 5G Home LVSKIHP InDoorUnit (IDU) 3.4.66.162 does not validate the user-provided URL within the crtcmode function's enable_ssh sub-operation of the crtcrpc JSON listener (found at /lib/functions/wnc_jsonsh/crtcmode.sh) A remote attacker on the local network can provide a malicious URL. The data (found at that URL) is written to /usr/sbin/dropbear and then executed as root.
