CVE-2019-11107
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 the subsystem for Intel(R) AMT before version 12.0.45 may allow an unauthenticated user to potentially enable escalation of privilege via network 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 confidenceInsufficient input validation in the Intel(R) AMT (Active Management Technology) subsystem allows an unauthenticated attacker to escalate privileges via network access before version 12.0.45. This is a pre-authentication flaw enabling network-based 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.
-
Verify Intel AMT is present and enabledCheck the system BIOS/UEFI settings for Intel AMT (Active Management Technology) status, or use Intel tools such as the Intel Management Engine (ME) Analyzer, or run `wmic /namespace:\\root\cimv2\intelmeci get /all` on Windows to query AMT status.Affected if Intel AMT is present and enabled on the system.
-
Determine Intel AMT firmware versionRetrieve the AMT firmware version using Intel's AMT SDK, `intelmetool` on Linux, or via the Intel Management Engine BIOS update interface. The version is typically displayed as a build number in the format like 12.0.x.x.Affected if The installed firmware version falls within the range >= 12.0.0 and < 12.0.45.
-
Confirm network accessibility of AMT interfaceVerify that the Intel AMT network interface is configured and accessible. Check if port 16992 (HTTP) or 16993 (HTTPS) is listening on the network, or review the AMT network configuration via the Intel AMT configuration console.Affected if Intel AMT is network-accessible, which is required for the network-based privilege escalation vector described in the CVE.
A system is affected if Intel AMT is enabled, network-accessible, and the firmware version is 12.0.x where x is less than 45 (i.e., versions 12.0.0 through 12.0.44).

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped12.0.45
Upgrade Intel AMT firmware to version 12.0.45 or later to address the input validation vulnerability.
Intel AMT firmware version 12.0.45
- Identify systems with Intel Active Management Technology (AMT) firmware versions 12.0 through 12.0.44
- Obtain the Intel AMT firmware update from the official Intel support website or your system OEM
- Follow your system manufacturer's recommended procedure for updating Intel AMT firmware, typically via Intel Management Engine BIOS Extension (MEBx) or OEM management tools
- Verify the firmware has been updated to version 12.0.45 or later
- Confirm the Intel AMT version post-update matches the fixed release
