CVE-2022-28369 WRITEUP CRITICAL WRITEUP
Verizon 5G Home LVSKIHP InDoorUnit IDU 3.4.66.162 - RCE
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.
CVSS 9.8
CVE-2022-28370 WRITEUP HIGH WRITEUP
Verizon 5G Home LVSKIHP ODU 3.33.101.0 - Code Injection
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.
CVSS 7.5
CVE-2022-28371 WRITEUP HIGH WRITEUP
Verizon 5G Home LVSKIHP InDoorUnit/ODU <3.4.66.162/<3.33.101.0 - In...
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 logs.)

CVE-2022-28372 WRITEUP HIGH WRITEUP
Verizon 5G Home LVSKIHP IDU/ODU - File Upload
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).

CVE-2022-28373 WRITEUP CRITICAL WRITEUP
Verizon 5G Home LVSKIHP IDU 3.4.66.162 - RCE
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.
CVSS 9.8
CVE-2022-28374 WRITEUP HIGH WRITEUP
Verizon 5G Home LVSKIHP ODU <3.33.101.0 - RCE
Verizon 5G Home LVSKIHP OutDoorUnit (ODU) 3.33.101.0 does not property sanitize user-controlled parameters within the DMACC URLs on the Settings page of the Engineering portal. An authenticated remote attacker on the local network can inject shell metacharacters into /usr/lib/lua/5.1/luci/controller/admin/settings.lua to achieve remote code execution as root.
CVSS 8.8
CVE-2022-28375 WRITEUP CRITICAL WRITEUP
Verizon 5G Home LVSKIHP ODU <3.33.101.0 - RCE
Verizon 5G Home LVSKIHP OutDoorUnit (ODU) 3.33.101.0 does not property sanitize user-controlled parameters within the crtcswitchsimprofile function of the crtcrpc JSON listener. A remote attacker on the local network can inject shell metacharacters into /usr/lib/lua/5.1/luci/controller/rpc.lua to achieve remote code execution as root,
CVSS 9.8
CVE-2022-28376 WRITEUP HIGH WRITEUP
Verizon 5G Home LVSKIHP - Info Disclosure
Verizon 5G Home LVSKIHP outside devices through 2022-02-15 allow anyone (knowing the device's serial number) to access a CPE admin website, e.g., at the 10.0.0.1 IP address. The password (for the verizon username) is calculated by concatenating the serial number and the model (i.e., the LVSKIHP string), running the sha256sum program, and extracting the first seven characters concatenated with the last seven characters of that SHA-256 value.
CVSS 8.1
CVE-2022-28377 WRITEUP HIGH WRITEUP
Verizon 5G Home - Auth Bypass
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).
