On Verizon 5G Home LVSKIHP OutDoorUnit (ODU) 3.33.101.0 devices, the RPC endpoint crtc_fw_upgrade provides a means of provisioning a firmware update for the device. /lib/functions/wnc_jsonsh/wnc_crtc_fw.sh has no cryptographic validation of the image, thus allowing an attacker to modify the installed firmware.
