Security Vulnerabilities
- CVEs Published In July 2022
A denial of service vulnerability exists in some Xiaomi models of phones. The vulnerability is caused by heap overflow and can be exploited by attackers to make remote denial of service.
In convert2rhel, there's an ansible playbook named ansible/run-convert2rhel.yml which passes the Red Hat Subscription Manager user password via the CLI to convert2rhel. This could allow unauthorized local users to view the password via the process list while convert2rhel is running. However, this ansible playbook is only an example in the upstream repository and it is not shipped in officially supported versions of convert2rhel.
A buffer overflow in the httpd daemon on TP-Link TL-WR841N V12 (firmware version 3.16.9) devices allows an authenticated remote attacker to execute arbitrary code via a GET request to the page for the System Tools of the Wi-Fi network. This affects TL-WR841 V12 TL-WR841N(EU)_V12_160624 and TL-WR841 V11 TL-WR841N(EU)_V11_160325 , TL-WR841N_V11_150616 and TL-WR841 V10 TL-WR841N_V10_150310 are also affected.
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.
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.
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.)
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).
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.
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.
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,
