CVE-2019-3649
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 · uneditedInformation Disclosure vulnerability in McAfee Advanced Threat Defense (ATD) prior to 4.8 allows remote authenticated attackers to gain access to hashed credentials via carefully constructed POST request extracting incorrectly recorded data from log files.
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 confidenceMcAfee Advanced Threat Defense versions prior to 4.8 contain an information disclosure vulnerability where hashed credentials are incorrectly recorded in log files. Authenticated remote attackers can use specially crafted POST requests to extract these hashed credentials from the logs.

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.
-
Determine McAfee ATD installed versionAccess the ATD administration interface and navigate to System > About, or check the version via the command line interface if availableAffected if Version is displayed as less than 4.8
-
Locate ATD log filesAccess the log directory through the ATD interface or file system - typically found under the logs or /var/log directory accessible to administratorsAffected if Log files exist and contain POST request records
-
Search logs for credential hash patternsUse grep or a text search tool to look for patterns resembling hashed credentials in the log files - look for strings containing $ or alphanumeric sequences following keywords like 'password', 'credential', or 'auth'Affected if Any hashed password strings appear in the logs
-
Review POST request loggingExamine access and application logs for POST requests, particularly those related to authentication or credential submissionAffected if POST requests with authentication data are logged in plaintext or hashed form
Your environment is affected if McAfee ATD version is below 4.8 AND log files contain any hashed credential entries from authentication POST requests.

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 data4.8
Upgrade McAfee ATD to version 4.8 or later, and consider credential rotation as a precautionary measure since plaintext or incorrectly logged credentials may have been exposed.
