CVE-2020-0597
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 · uneditedOut-of-bounds read in IPv6 subsystem in Intel(R) AMT and Intel(R) ISM versions before 14.0.33 may allow an unauthenticated user to potentially enable denial of service 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 confidenceAn out-of-bounds read vulnerability exists in the IPv6 subsystem of Intel AMT (Active Management Technology) and ISM (Intel Standard Manageability) versions prior to 14.0.33. An unauthenticated remote attacker can exploit this via network access to potentially cause a denial of service condition.

It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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 or ISM is present and enabledAccess the system BIOS/UEFI settings or use Intel AMT discovery tools to verify that Intel AMT or ISM technology is provisioned and active on the system.Affected if Intel AMT or ISM is not present or is disabled, the vulnerability does not apply.
-
Identify the Intel AMT or ISM versionUse Intel Management Engine interface tools, Intel AMT configuration utilities, or check the firmware version reported in the AMT/ISM control panel or via management interfaces (e.g., WMI, Redfish, or IPMI).Affected if The version cannot be determined, assume potentially affected and treat as vulnerable.
-
Compare installed version against affected rangesCheck if the installed version falls within any of these ranges: 11.0 to 11.8.76, 11.10 to 11.11.76, 11.20 to 11.22.76, 12.0 to 12.0.63, 13.0 to 13.0.31, or 14.0 to 14.0.32.Affected if The installed version is within any of these ranges, the system is affected by the vulnerability.
-
Verify IPv6 is enabled for AMT/ISMCheck the AMT/ISM network configuration settings to determine if IPv6 support is enabled for the management interface.Affected if IPv6 is disabled for AMT/ISM, the specific attack vector may not be reachable, though the vulnerable code may still be present.
A system is affected if it has Intel AMT or ISM enabled with a version between 11.0 and 14.0.32 inclusive, and IPv6 management access is available.

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 dataUpdate Intel AMT and ISM to version 14.0.33 or later. If immediate patching is not possible, consider disabling AMT/ISM or restricting network access to management interfaces.
