CVE-2018-16201
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 · uneditedToshiba Home gateway HEM-GW16A 1.2.9 and earlier, Toshiba Home gateway HEM-GW26A 1.2.9 and earlier uses hard-coded credentials, which may allow an attacker on the same network segment to login to the administrators settings screen and change the configuration or execute arbitrary OS commands.
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 confidenceToshiba Home gateway HEM-GW16A and HEM-GW26A devices with firmware 1.2.9 and earlier contain hard-coded credentials embedded in the firmware. An attacker with network access to the same segment can use these credentials to authenticate to the administrative web interface and gain full control of the device, including the ability to modify configuration settings and execute arbitrary operating system commands.

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 device modelInspect the physical device label or access the administrative web interface to confirm the model number is HEM-GW16A or HEM-GW26AAffected if Device model is Toshiba HEM-GW16A or HEM-GW26A
-
Check firmware versionAccess the device administrative web interface and navigate to the system information or firmware version page, or check the device label for firmware version printedAffected if Firmware version is 1.2.9 or lower
-
Verify administrative web interface is exposedPerform a network port scan of the device to check if HTTP (port 80) or HTTPS (port 443) administrative interfaces are accessible from the networkAffected if Administrative web interface is reachable over the network from an attacker-controlled segment
-
Confirm hardcoded credentials presenceIf firmware binary or image is accessible (through firmware extraction, backup, or update file), search for hardcoded username/password strings within the binaryAffected if Hardcoded credentials are found embedded in the firmware binary
The environment is affected if the device is a Toshiba HEM-GW16A or HEM-GW26A running firmware version 1.2.9 or lower with an accessible administrative web interface on the network.

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. Prior to patch, isolate affected devices on a restricted network segment and monitor for unauthorized administrative access attempts.
