CVE-2020-7328
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 · uneditedExternal entity attack vulnerability in the ePO extension in McAfee MVISION Endpoint prior to 20.11 allows remote attackers to gain control of a resource or trigger arbitrary code execution via improper input validation of an HTTP request, where the content for the attack has been loaded into ePO by an ePO administrator.
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 confidenceExternal entity attack vulnerability in McAfee ePO extension prior to 20.11 allows remote attackers to gain control of a resource or trigger arbitrary code execution via improper input validation of HTTP requests. The attack requires malicious content to first be loaded into ePO by an ePO administrator, making this a multi-stage attack vector.

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.
-
Check installed MVISION Endpoint versionOpen McAfee ePO console or use the MVISION Endpoint client to view the installed version. Look for the product version information in theAbout or System Information section.Affected if Version is below 20.11
-
Verify ePO extension is enabledIn the ePO console, navigate to the Extensions or Server Settings menu to confirm whether the MVISION Endpoint ePO extension is installed and active.Affected if The ePO extension is present and enabled
-
Review ePO administrative accessCheck the ePO User Management section to list all users with Administrator privileges. Verify the number and identity of admin accounts.Affected if Multiple untrusted or compromised accounts have administrative rights
-
Inspect loaded extensions and contentIn ePO console, go to the Extensions or Repository section to list all loaded extensions, scripts, or content packages. Look for any unrecognized or suspicious entries.Affected if Any unverified or malicious-looking extensions are loaded into ePO
You are affected if MVISION Endpoint version is below 20.11 and the ePO extension is enabled, especially if untrusted extensions or administrator accounts exist in the environment.

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 data20.11
Upgrade McAfee MVISION Endpoint to version 20.11 or later. Until then, restrict ePO administrative access to trusted personnel only and carefully validate any extensions or content before loading them into the ePO system.
