CVE-2020-8707
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 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 confidenceA buffer overflow vulnerability exists in the daemon component of Intel Server Boards, Server Systems, and Compute Modules prior to version 1.59. An unauthenticated attacker with adjacent network access can exploit this buffer overflow to potentially achieve privilege escalation. The vulnerability stems from improper bounds checking in the daemon that handles adjacent network requests.

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 physical server chassis, or run commands like `dmidecode -s system-product-name` or `ipmitool fru print` to retrieve the product name remotely.Affected if The model matches one of: S2600wt, R1000wt, R2000wt, S2600cw, Hns2600kp, S2600kp, Hns2600tp, or S2600tp.
-
Retrieve the current firmware versionUse IPMI or BMC web interface to check the firmware version. Command example: `ipmitool mc info` or access the BMC/Intel Remote Management Module web interface under Firmware/BIOS version information.Affected if The firmware version is below 1.59 (for example, 1.58, 1.50, etc.).
-
Verify the daemon component is accessibleDetermine if the BMC/management interface is reachable on the adjacent network. Check if ports used by the Intel server management daemon (typically ports 623 UDP, 443 HTTPS for BMC) are exposed to untrusted network segments.Affected if The management interface is accessible from an adjacent (untrusted) network segment.
-
Confirm the vulnerable daemon is runningCheck BMC status via IPMI: `ipmitool mc getsysbootinfo` or verify the BMC service is active. The vulnerability exists in the daemon handling adjacent network requests.Affected if The BMC/management daemon is active and handling network requests from an adjacent network.
You are affected if your Intel Server Board, System, or Compute Module matches one of the listed models AND runs firmware version earlier than 1.59 AND has the management interface accessible from an 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 Intel Server Board, Server System, or Compute Module firmware to version 1.59 or later to remediate this vulnerability. If immediate patching is not possible, restrict adjacent network access to trusted parties only.
