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 McAfee MNE installationCheck if McAfee Management of Native Encryption is installed on the system by reviewing installed programs or checking for MNE-related servicesAffected if MNE is not installed - not affected; MNE is installed - continue to version check
-
Determine installed MNE versionUse system inventory tools, product console, or packaging metadata to identify the exact version of McAfee Management of Native Encryption installedAffected if Cannot determine version - treat as potentially affected
-
Compare version against affected rangeCompare your installed MNE version to the affected range of versions before 4.1.4Affected if Installed version is 4.1.4 or later - not affected; installed version is below 4.1.4 - continue to service check
-
Verify MNE service is runningCheck if the McAfee MNE service or daemon is actively running on the systemAffected if MNE service is not running - vulnerability not currently exploitable; MNE service is running - system is affected by this CVE
Your environment is affected if McAfee Management of Native Encryption is installed with a version lower than 4.1.4 and the MNE service is actively running, allowing local authenticated users to potentially manipulate input for privilege escalation.
