CVE-2020-12334
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 · uneditedImproper permissions in the installer for the Intel(R) Advisor tools before version 2020 Update 2 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 confidenceThe Intel Advisor installer before version 2020 Update 2 had improper file system permissions that allowed an authenticated local user to modify installer files or installation directories, potentially enabling local privilege escalation.

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 if Intel Advisor is installedOpen Programs and Features (or run 'appwiz.cpl') and search for Intel Advisor in the list of installed applications, or check for the installation directory (commonly in Program Files or Program Files (x86)\Intel\Advisor)Affected if Intel Advisor is not present on the system (not affected)
-
Determine the installed Intel Advisor versionIn Programs and Features, locate Intel Advisor and note the version shown in the Version column. Alternatively, check the version.xml or version.txt file in the Intel Advisor installation directoryAffected if The displayed version is 2020 or any version number below 2020 (v19.x, v18.x, etc.)
-
Confirm if version 2020 has Update 2 appliedIf the version shows as '2020' without Update 2 mentioned, inspect the installation directory for a version file or check the Intel Advisor help/about section to see if it displays 'Update 2' or laterAffected if Version shows as Intel Advisor 2020 (without Update 1 or Update 2), or 2020 Update 1, indicating the vulnerability is present
-
Verify file permissions on the installation directoryRight-click the Intel Advisor installation folder, go to Properties > Security tab, and check if standard authenticated users have Write or Modify permissions to the main installation directory (not subfolders)Affected if Authenticated users have Write or Modify permissions to the root installation directory, confirming the insecure permission state described in the CVE
The system is affected if Intel Advisor version 2020 (without Update 2) or earlier is installed and authenticated users have write access to the installation directory.
