CVE-2020-8706
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 · uneditedBuffer overflow in a daemon for some Intel(R) Server Boards, Server Systems and Compute Modules before version 1.59 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 confidenceBuffer overflow vulnerability in an Intel server daemon (used for Server Boards, Server Systems, and Compute Modules) allows an unauthenticated attacker with adjacent network access to potentially escalate privileges by overflowing a buffer in the affected daemon.

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 label on the physical server chassis or use system inventory tools (e.g., Intel Server Management SDK, IPMI, or BIOS information) to determine the exact model number (e.g., S2600wt, R1000wt, Hns2600kp)Affected if The model matches one of the affected products listed in the CVE (S2600wt, R1000wt, R2000wt, S2600cw, Hns2600kp, S2600kp, Hns2600tp, S2600tp)
-
Determine the current firmware versionAccess the BMC (Baseboard Management Controller) web interface or use command-line tools such as ipmitool (e.g., 'ipmitool raw' or 'ipmitool fru print') or Intel Deployment Toolkit to retrieve the firmware version of the affected daemon or system firmwareAffected if Unable to retrieve firmware version or version information shows < 1.59 (e.g., 1.50, 1.40, etc.)
-
Verify the affected daemon is runningCheck if the Intel server daemon (typically the Intel Server Platform Services daemon or similar BMC-related service) is active and accessible via the network. This may require checking BMC status via IPMI or contacting the BMC IP address on the local networkAffected if The daemon is running and accessible via adjacent network (same broadcast domain/L2 network)
-
Confirm firmware version is below the patched releaseCompare the installed firmware version against the fixed version 1.59. If the product model is in the affected list and the firmware version displayed is less than 1.59 (e.g., 1.58, 1.50, 1.30), the system is vulnerableAffected if Firmware version is < 1.59 for any of the affected product models listed
Your environment is affected if you are running any of the listed Intel server products with firmware version below 1.59, and the server daemon is accessible on the adjacent network.

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 the Intel server firmware/software to version 1.59 or later to obtain the patched daemon; apply network segmentation to restrict adjacent access as a compensating control.
