CVE-2020-0533
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 · uneditedReversible one-way hash in Intel(R) CSME versions before 11.8.76, 11.12.77 and 11.22.77 may allow a privileged user to potentially enable escalation of privilege, denial of service or information disclosure 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 confidenceIntel CSME firmware versions before 11.8.76, 11.12.77, and 11.22.77 contain a reversible one-way hash vulnerability. This allows a privileged local attacker to potentially reverse the hash, leading to privilege escalation, denial of service, or information disclosure.

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.
-
Identify if system has Intel CSME firmwareCheck if the system uses an Intel processor with CSME (Converged Security Management Engine) by looking for Intel vPro, Active Management Technology (AMT), or Intel Management Engine features in system documentation or BIOS information.Affected if System does not have Intel CSME firmware (not affected)
-
Determine Intel CSME firmware versionUse the Intel CSME Version Detection Tool (available from Intel support) or check the BIOS/UEFI firmware settings under 'Intel Management Engine' or 'Intel ME' section to find the firmware version number.Affected if Unable to determine the installed CSME firmware version
-
Compare version to affected rangesIf version is 11.x, compare against: version < 11.8.76, OR version >= 11.10 and < 11.12.77, OR version >= 11.20 and < 11.22.77. Any of these mean the system is affected.Affected if Installed version falls within any of the affected ranges: >= 11.0 and < 11.8.77, OR >= 11.10 and < 11.12.77, OR >= 11.20 and < 11.22.77
The system is affected if it has Intel CSME firmware with a version that falls into any of the three vulnerable ranges (less than 11.8.77, 11.10-11.12.76, or 11.20-11.22.76).
