CVE-2020-0531
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 in Intel(R) AMT versions before 11.8.77, 11.12.77, 11.22.77 and 12.0.64 may allow an authenticated user to potentially enable information disclosure 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 confidenceIntel Active Management Technology (AMT) contains an improper input validation vulnerability that allows authenticated users to potentially disclose sensitive information through network access.

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 for Intel AMT availability: On Windows, open Device Manager and look for 'Intel Management Engine Interface' under 'System devices'. On Linux, run 'ls /dev/mei*' or check 'dmidecode' output for AMT entries. Alternatively, access the AMT configuration via BIOS/UEFI (typically pressing F2, F12, or Delete at boot, then navigating to Intel AMT or Active Management Technology settings).Affected if Intel AMT is not present or is disabled, the system is not affected by this vulnerability.
-
Determine Intel AMT firmware versionUse the Intel Management Engine Interface to retrieve the AMT firmware version. On Windows, you can use the Intel ME System Tools or check via WMI: 'wmic /namespace:\\root\cimv2\Intel_AMT get Version'. On Linux, run 'mei-amt-version' if available, or check /sys/class/mei/*/fw_version. In BIOS/UEFI, the AMT version may be visible in the Intel AMT configuration screen under 'General Information' or 'Firmware Version'.Affected if Unable to retrieve an AMT firmware version indicates AMT may not be fully configured or accessible.
-
Compare installed version against affected rangesMatch the detected AMT firmware version to these affected ranges: 11.0 <= version < 11.8.77, OR 11.10 <= version < 11.12.77, OR 11.20 <= version < 11.22.77, OR 12.0 <= version < 12.0.64. If the version matches any of these ranges, the system is vulnerable. Versions 11.8.77, 11.12.77, 11.22.77, and 12.0.64 or later contain the fix.Affected if The version falls within any of the four affected ranges listed above.
The system is affected if Intel AMT is enabled and the firmware version matches any of the four vulnerable ranges: 11.0-11.8.76, 11.10-11.12.76, 11.20-11.22.76, or 12.0-12.0.63.
