CVE-2021-0100
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 · uneditedIncorrect default permissions in the installer for the Intel(R) SSD Data Center Tool, versions downloaded before 12/31/2020, 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(R) SSD Data Center Tool installer distributed before December 31, 2020 had incorrect default permissions that allowed authenticated local users to modify executable files or access sensitive resources, 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 SSD Data Center Tool is installedLook for the installation directory, typically under C:\Program Files\Intel\Intel SSD Data Center Tool or C:\Program Files (x86)\Intel\Intel SSD Data Center Tool. Also check Add/Remove Programs or Programs and Features for the application entry.Affected if The application is installed on the system
-
Identify the installed version or installation dateRight-click the application in Add/Remove Programs and select Properties, or check the executable file properties (typically iscsiMgmt.exe or similar in the installation folder) for the version info or creation date.Affected if The version listed or the file creation date is before December 31, 2020
-
Verify file permissions on executable filesRight-click on executable files in the installation directory (such as .exe files), go to Properties, then the Security tab, and check the permissions for Users or authenticated local user groups.Affected if Users or authenticated users have Write or Modify permissions on executable files in the installation directory
The system is affected if Intel SSD Data Center Tool is installed with a version or installation date prior to December 31, 2020 and executable files grant write/modify permissions to non-admin users.
