CVE-2022-36443
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in Zebra Enterprise Home Screen 4.1.19. The device allows the administrator to lock some communication channels (wireless and SD card) but it is still possible to use a physical connection (Ethernet cable) without restriction.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceZebra Enterprise Home Screen 4.1.19 implements administrative controls to lock wireless and SD card communication channels, but fails to restrict physical Ethernet connections, allowing unrestricted network access despite configured device policies.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Zebra Enterprise Home Screen versionCheck the installed version of Zebra Enterprise Home Screen on the device through Settings > Apps > Enterprise Home Screen, or via ADB command: adb shell dumpsys package com.zebra.enterprisehomescreen | grep versionNameAffected if The installed version is exactly 4.1.19
-
Check Ethernet connection statusInspect the device network settings or status panel to determine if Ethernet is connected and active. On the device, go to Settings > Network & Internet > Ethernet, or use ADB: adb shell settings get global ethernet_onAffected if Ethernet is physically connected or enabled on the device
-
Verify wireless and SD card restrictions are configuredAccess the Enterprise Home Screen administrative interface and review the configured device policies under the lockdown settings for wireless and SD card communication channelsAffected if Wireless and SD card restrictions are enabled in the device policy but Ethernet connectivity remains unrestricted
The environment is affected if Zebra Enterprise Home Screen version 4.1.19 is installed with wireless or SD card restrictions configured while Ethernet connectivity is available and unrestricted.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement network segmentation and firewall rules at the infrastructure level to restrict Ethernet connectivity, and apply any vendor firmware updates that address this access control bypass.
