CVE-2019-11103
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 · uneditedInsufficient input validation in firmware update software for Intel(R) CSME before versions 12.0.45,13.0.10 and 14.0.10 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 confidenceVulnerability in Intel CSME (Converged Security and Management Engine) firmware update software due to insufficient input validation. An authenticated local user can potentially exploit this to escalate privileges. CSME is a critical firmware component handling security management on Intel platforms.

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 CSME firmware is presentCheck if the system has Intel CSME/ME firmware. On Windows, open Device Manager and look under 'System devices' for 'Intel(R) Management Engine Interface' or 'Intel(R) Converged Security Management Engine'. On Linux, run 'ls /dev/mei*' or use 'meinfo' tool if available.Affected if The system does not have Intel CSME firmware (not affected, different hardware)
-
Retrieve CSME firmware versionUse Intel tools to read the firmware version. On Windows, use 'Intel Management Engine Interface' driver properties or tools like 'MEInfo' or 'intelmetool'. On Linux, run 'meinfo' or 'intelmetool' from terminal. The version typically appears as a numeric build like 12.x.x.x or 13.x.x.x.Affected if Unable to retrieve version - CSME may be disabled or inaccessible
-
Compare version against affected rangesCompare your installed CSME firmware version to: 12.0.0 to 12.0.44 (affected), 13.0.0 to 13.0.9 (affected), 14.0.0 to 14.0.9 (affected). Versions below 12.0, or 12.0.45 and above, 13.0.10 and above, 14.0.10 and above are NOT affected.Affected if Installed version falls within any of these ranges: >= 12.0 and < 12.0.45 OR >= 13.0 and < 13.0.10 OR >= 14.0.0 and < 14.0.10
A system is affected if it contains Intel CSME firmware with a version matching the affected ranges listed above, making it vulnerable to local privilege escalation via insufficient input validation.

From vendor data12.0.4513.0.1014.0.10
Update Intel CSME firmware to versions 12.0.45, 13.0.10, 14.0.10 or later. In enterprise environments, test updates on representative systems before broad deployment due to firmware update risks.
