CVE-2019-3662
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 · uneditedPath Traversal: '/absolute/pathname/here' vulnerability in McAfee Advanced Threat Defense (ATD) prior to 4.8 allows remote authenticated attacker to gain unintended access to files on the system via carefully constructed HTTP requests.
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 confidencePath traversal vulnerability in McAfee Advanced Threat Defense (ATD) versions prior to 4.8 allows authenticated remote attackers to access arbitrary files on the system by sending specially crafted HTTP requests containing absolute path traversal sequences.

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 if McAfee ATD is installedLocate the McAfee Advanced Threat Defense installation in your environment. Check for the ATD web interface or service running on your system.Affected if McAfee ATD is present in the environment
-
Determine the installed ATD versionAccess the ATD web interface and navigate to the About or System Information page to view the current version number, or use the system administration console to retrieve the version.Affected if The installed version is lower than 4.8
-
Verify the web interface is network-accessibleConfirm that the McAfee ATD web interface (typically on port 443 or 8443) is reachable from network segments that could contain an attacker.Affected if The ATD web interface is exposed to untrusted networks
-
Check for accessible authentication endpointsReview the ATD configuration to determine if remote authentication is enabled for the web interface.Affected if Remote authentication is enabled and the interface is accessible externally
You are affected if McAfee Advanced Threat Defense version 4.8 or later is not installed and the ATD web interface is network-accessible with authentication enabled.

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 to obtain the patch for this path traversal vulnerability. Additionally, network segmentation and strict access controls can limit exposure until the upgrade is applied.
