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 · unedited
Incorrect default permissions in some Intel(R) CSME installer software before version 2328.5.5.0 may allow an authenticated user to potentially enable escalation of privilege via local access.

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 confidence

The Intel CSME (Converged Security and Management Engine) installer software versions prior to 2328.5.5.0 shipped with incorrect default file system permissions. An authenticated local user could exploit these misconfigured permissions to gain elevated privileges on the system where the installer is run.

MitigationUpgrade Intel CSME installer software to version 2328.5.5.0 or later to obtain the corrected default permissions.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate Intel CSME installer software on the system
    Search program files directories and any Intel installation folders for files containing 'CSME' or 'Converged Security' in the name, or look for Intel installer packages related to CSME
    Affected if The installer software is present on the system and its version is below 2328.5.5.0
  2. Determine the installed version of the Intel CSME installer
    Right-click the installer executable, select Properties, and view the Details tab to find the File Version or Product Version field
    Affected if The displayed version number is less than 2328.5.5.0 (for example, 2328.x.x.x versions below 2328.5.5.0, or any earlier major version)
  3. Check Windows Installed Programs for CSME installer entry
    Open Programs and Features (appwiz.cpl) or the Registry at HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall to look for installed Intel CSME-related software and note its version
    Affected if An Intel CSME installer entry exists with a version string earlier than 2328.5.5.0

Your system is affected if the Intel CSME installer software version is present and is any version prior to 2328.5.5.0, as only version 2328.5.5.0 and later contain the corrected default file system permissions.
