CVE-2020-8730
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 · uneditedHeap-based overflow for some Intel(R) Server Boards, Server Systems and Compute Modules before version 1.59 may allow an authenticated user to potentially enable escalation of privilege 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 · moderate confidenceA heap-based buffer overflow vulnerability exists in Intel Server Boards, Server Systems, and Compute Modules before version 1.59. The flaw allows an authenticated local user to potentially escalate privileges via heap memory corruption. This is a firmware-level vulnerability affecting Intel server hardware infrastructure.

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 the Intel server product modelLocate the product model label on the server chassis or access the BMC web interface to view system information. Confirm the model is one of: S2600wt, R1000wt, R2000wt, S2600cw, Hns2600kp, S2600kp, Hns2600tp, or S2600tp.Affected if The product model matches one of the affected models listed in the CVE.
-
Retrieve the current firmware versionAccess the BMC (Baseboard Management Controller) web interface or use IPMI commands such as 'ipmitool -I lanplus -H <BMC_IP> -U <user> -P <pass> raw' to query the BMC for firmware revision. Alternatively, check via Intel Server Management software or Intel System Information Viewer.Affected if Unable to retrieve firmware version or version data is unavailable.
-
Compare firmware version to 1.59Review the obtained firmware version number against the affected version range. The vulnerability affects versions before 1.59.Affected if The installed firmware version is less than 1.59.
-
Verify local authenticated access existsDetermine if local user accounts are configured on the BMC or server OS with privileges sufficient to exploit the flaw. Review user access controls and account permissions.Affected if Local authenticated user accounts exist on the system and the firmware version is below 1.59.
You are affected if your Intel server product model matches one of the listed affected models AND the installed firmware version is below 1.59 AND local authenticated user access is present.

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 data1.59
Update Intel server firmware to version 1.59 or later to remediate the vulnerability. In the interim, limit local access to trusted personnel and monitor for unauthorized access attempts.
