CVE-2019-15805
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 · uneditedCommScope ARRIS TR4400 devices with firmware through A1.00.004-180301 are vulnerable to an authentication bypass to the administrative interface because they include the current base64 encoded password within http://192.168.1.1/login.html. Any user connected to the Wi-Fi can exploit this.
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 confidenceThe CommScope ARRIS TR4400 router with firmware through A1.00.004-180301 contains an authentication bypass vulnerability where the administrative password (base64 encoded) is directly exposed in the HTML source code of the login page at http://192.168.1.1/login.html. Any user connected to the Wi-Fi network can view the page source, decode the base64 password, and gain full administrative access to the device without legitimate credentials.

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.
-
Confirm device is an ARRIS TR4400 routerAccess the router admin interface at http://192.168.1.1 or check the device label/marketing materials for the model number ARRIS TR4400Affected if The device is not an ARRIS TR4400 model
-
Check the firmware versionLog into the router admin interface and navigate to the status or firmware information page to identify the installed firmware versionAffected if Firmware version is a1.00.004-180301 or earlier
-
Inspect login page HTML source for exposed credentialsNavigate to http://192.168.1.1/login.html, right-click and select 'View Page Source' or 'Inspect', then search for 'password' or base64-encoded strings in the HTMLAffected if The HTML source contains a base64-encoded password string that can be decoded to reveal the administrative credentials
A user is affected if they own an ARRIS TR4400 router running firmware a1.00.004-180301 or earlier AND the login.html page HTML source contains a base64-encoded password string.

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 the latest vendor firmware update for the ARRIS TR4400 to remove the credential exposure. If no firmware patch is available, segment the device on a restricted VLAN or replace the device with a model receiving active security updates.
