14 Jul 2022 — 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.

14 Jul 2022 — On Verizon 5G Home LVSKIHP InDoorUnit (IDU) 3.4.66.162 and OutDoorUnit (ODU) 3.33.101.0 devices, the CRTC and ODU RPC endpoints rely on a static certificate for access control. This certificate is embedded in the firmware, and is identical across the fleet of devices. An attacker need only download this firmware and extract the private components of these certificates (from /etc/lighttpd.d/ca.pem and /etc/lighttpd.d/server.pem) to gain access. (The firmware download location is shown in a device's upgrade l... • https://github.com/JousterL/SecWriteups/blob/main/Verizon%20LVSKIHP%205G%20Modem/readme.md • CWE-798: Use of Hard-coded Credentials •

14 Jul 2022 — On Verizon 5G Home LVSKIHP InDoorUnit (IDU) 3.4.66.162 and OutDoorUnit (ODU) 3.33.101.0 devices, the CRTC and ODU RPC endpoints provide a means of provisioning a firmware update for the device via crtc_fw_upgrade or crtcfwimage. The URL provided is not validated, and thus allows for arbitrary file upload to the device. This occurs in /lib/lua/luci/crtc.lua (IDU) and /lib/functions/wnc_jsonsh/wnc_crtc_fw.sh (ODU).

14 Jul 2022 — Verizon 5G Home LVSKIHP InDoorUnit (IDU) 3.4.66.162 does not properly sanitize user-controlled parameters within the crtcreadpartition function of the crtcrpc JSON listener in /usr/lib/lua/luci/crtc.lua. A remote attacker on the local network can inject shell metacharacters to achieve remote code execution as root.

14 Jul 2022 — On Verizon 5G Home LVSKIHP InDoorUnit (IDU) 3.4.66.162 and OutDoorUnit (ODU) 3.33.101.0 devices, the CRTC and ODU RPC endpoints rely on a static account username/password for access control. This password can be generated via a binary included in the firmware, after ascertaining the MAC address of the IDU's base Ethernet interface, and adding the string DEVICE_MANUFACTURER='Wistron_NeWeb_Corp.' to /etc/device_info to replicate the host environment. This occurs in /etc/init.d/wnc_factoryssidkeypwd (IDU). En ... • https://github.com/JousterL/SecWriteups/blob/main/Verizon%20LVSKIHP%205G%20Modem/readme.md • CWE-521: Weak Password Requirements •
