CVE-2020-8101
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 · uneditedImproper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in HTTP interface of ADT LifeShield DIY HD Video Doorbell allows an attacker on the same network to execute commands on the device. This issue affects: ADT LifeShield DIY HD Video Doorbell version 1.0.02R09 and prior versions.
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 · moderate confidenceCommand injection vulnerability in the HTTP interface of ADT LifeShield DIY HD Video Doorbell allows an attacker on the same network segment to inject and execute arbitrary operating system commands on the device by sending specially crafted HTTP requests.

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 the device on the networkScan the local network for devices matching ADT LifeShield DIY HD Video Doorbell. Use network scanning tools (such as nmap, Angry IP Scanner, or similar) to discover devices. Look for device hostname, MAC OUI, or HTTP service banners that indicate this specific doorbell model.Affected if The device is present on the network and is confirmed to be an ADT LifeShield DIY HD Video Doorbell.
-
Confirm HTTP interface is enabledAttempt to access the device's HTTP service by browsing to the device IP address on port 80 or 8080. Check if an HTTP response is received from the doorbell device.Affected if The HTTP interface is accessible and responds to requests.
-
Retrieve the firmware versionAccess the device HTTP interface and navigate to system information, device status, or settings pages where firmware version is typically displayed. Alternatively, check HTTP response headers or firmware update pages for version strings.Affected if The firmware version displayed is 1.0.02r09 or lower.
-
Verify network exposureDetermine if the device HTTP interface is accessible from network segments other than the intended local network. Check if the device is isolated on a restricted VLAN or if it accepts connections from multiple network segments.Affected if The device HTTP interface is reachable from network segments where untrusted users reside, or if the device is on a shared network without isolation.
The environment is affected if an ADT LifeShield DIY HD Video Doorbell with HTTP interface enabled is running firmware version 1.0.02r09 or lower and is accessible to attackers on the same network segment.

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 dataApply vendor firmware update when available; if no patch exists, isolate the device on a restricted VLAN with limited network access to reduce attack surface from adjacent attackers.
