CVE-2021-0126
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 input validation for the Intel(R) Manageability Commander before version 2.2 may allow an authenticated user to potentially enable escalation of privilege via adjacent 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 confidenceImproper input validation in Intel(R) Manageability Commander before version 2.2 allows an authenticated user to escalate privileges via adjacent network access. The vulnerability stems from insufficient validation of input data, which can be exploited to gain higher-level permissions than the user should have.

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.
-
Verify Intel Manageability Commander is installedCheck system for presence of Intel Manageability Commander softwareAffected if The software is installed on the system
-
Determine installed versionUse system inventory or product-specific command to retrieve the version number of Intel Manageability CommanderAffected if Installed version is less than 2.2 (e.g., 2.1, 2.0, or earlier)
-
Confirm service is running and accessibleCheck if Intel Manageability Commander service is active and listening on network portsAffected if Service is running and accessible via adjacent network
-
Review user account privilegesAudit user accounts that have authenticated access to Intel Manageability Commander and verify their assigned privilege levelsAffected if Users have authenticated access and the software fails to properly validate input for privilege assignments
You are affected if Intel Manageability Commander is installed with a version lower than 2.2 and the service is accessible, allowing an authenticated user to potentially escalate privileges through improper input validation.
