CVE-2019-11088
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 subsystem in Intel(R) AMT before versions 11.8.70, 11.11.70, 11.22.70 and 12.0.45 may allow an unauthenticated 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 confidenceInsufficient input validation in Intel(R) AMT (Active Management Technology) subsystem allows an unauthenticated user with adjacent network access to potentially escalate privileges. The vulnerability affects versions before 11.8.70, 11.11.70, 11.22.70, and 12.0.45.

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.
-
Confirm Intel AMT presenceOn Windows, open Device Manager and look for 'Intel(R) Management Engine Interface' under System devices. On Linux, check for /sys/class/mei/ directory or run 'ls /dev/mei*'. If the device exists, Intel AMT is present.Affected if Intel AMT hardware interface is found on the system
-
Retrieve Intel AMT firmware versionUse the Intel Management Engine Interface (MEI) driver with the Intel SA-00086 diagnostic tool, Intel AMT SDK, or the meinfo_cmd utility if available. Alternatively, access the Intel AMT web interface via https://localhost:16992 or the local KVM/redirection interface to view firmware version in the firmware information section.Affected if Unable to retrieve version indicates potential management difficulty but version data is needed for next step
-
Compare installed version against affected rangesCheck if the firmware version falls into any of these vulnerable ranges: 11.0 to 11.8.69, 11.10 to 11.11.69, 11.20 to 11.22.69, or 12.0 to 12.0.44. Compare the major.minor.build format of your version to these boundaries.Affected if Firmware version is lower than 11.8.70, 11.11.70, 11.22.70, or 12.0.45 in their respective branches
System is affected if Intel AMT is enabled and the firmware version falls within any of the vulnerable version ranges before the fixed releases.

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.
From vendor data11.8.7011.11.7011.22.70
Update Intel AMT firmware to version 11.8.70 or later (11.11.70, 11.22.70, 12.0.45 or higher) to remediate the input validation flaw.
