CVE-2022-2313
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 · uneditedA DLL hijacking vulnerability in the MA Smart Installer for Windows prior to 5.7.7, which allows local users to execute arbitrary code and obtain higher privileges via careful placement of a malicious DLL into the folder from where the Smart installer is being executed.
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 confidenceA DLL hijacking vulnerability in the MA Smart Installer for Windows versions prior to 5.7.7 allows local users to place a malicious DLL in the directory from which the installer is executed, causing the installer to load and execute the DLL with elevated privileges.

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 Agent versionOpen Windows Control Panel and navigate to Programs and Features or Add or Remove Programs. Locate McAfee Agent in the list and note the version number displayed.Affected if The displayed version is below 5.7.7
-
Locate the MA Smart InstallerSearch the system for the MA Smart Installer executable file used to deploy or update McAfee Agent. This is typically obtained from McAfee download repositories or enterprise distribution systems.Affected if The MA Smart Installer is present on the system and its version is below 5.7.7
-
Verify installer directory accessCheck the permissions on the directory from which the MA Smart Installer will be executed. Right-click the folder, select Properties, then Security, and review which users or groups have Write or Modify permissions.Affected if Non-administrative users have Write or Modify permissions to the installer execution directory
-
Compare version against CVE thresholdTake the identified version of the MA Smart Installer or McAfee Agent and compare it to the affected range: any version prior to 5.7.7.Affected if The installed version is prior to 5.7.7
The environment is affected if the McAfee Agent or MA Smart Installer version is below 5.7.7, enabling DLL hijacking when the installer runs from a directory with weak permissions.

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.
dbcve · scoped5.7.7
Upgrade the MA Smart Installer to version 5.7.7 or later which addresses the DLL hijacking vulnerability. As a temporary measure, ensure the installer is run from a controlled directory with restricted write permissions.
