CVE-2023-30768
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 · uneditedImproper access control in the Intel(R) Server Board S2600WTT belonging to the Intel(R) Server Board S2600WT Family with the BIOS version 0016 may allow a privileged 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 · high confidenceThis is an improper access control vulnerability in the BIOS (version 0016) of Intel S2600WTT and S2600WT family server boards. A user who already has privileged access can locally exploit this flaw to escalate their privileges to a higher authorization level. The vulnerability is firmware-based and requires local access to the server, not remote exploitation.

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 your Intel server board modelLocate the server board model number printed on the motherboard physical label or check system inventory/BMC inventory for the exact model (e.g., S1200v3rpl, S1200v3rpm, S1400fp2, etc.)Affected if The model matches any of these: S1200v3rpl, S1200v3rpm, S1200v3rpo, S1200v3rps, S1400fp2, S1400fp4, S1400sp4, S1400sp2
-
Check the installed BIOS firmware versionAccess the server locally (direct keyboard/video) or via IPMI/BMC web interface and retrieve the BIOS version from the firmware/BIOS information screen, or run: `dmidecode -s bios-version` or check BMC firmware inventory for BIOS versionAffected if The BIOS version returned is below 0006 for S1200v3 series boards, or below 0005 for S1400 series boards
-
Verify the vulnerability conditionCompare your detected BIOS version against the affected version thresholds: S1200v3 models need version 0006 or later, S1400 models need version 0005 or later. Also confirm you have a local user with privileged access (the exploit requires an existing privileged user account on the system)Affected if Your BIOS version is below the required threshold AND the server is accessible locally to a privileged user who could attempt escalation
You are affected if you are running an Intel S1200v3 or S1400 series server board with BIOS firmware below version 0006 or 0005 respectively, and the system is accessible to a local privileged user.

dbcve · scoped00050006
Apply the latest BIOS firmware update from Intel for the affected server board models. Verify the current BIOS version and schedule appropriate maintenance window for the firmware update, ensuring proper backup and rollback procedures are in place.
Server Board S1200v3 series: Firmware version 0006 | Server Board S1400 series: Firmware version 0005
- Identify the specific Intel Server Board model from the affected list (S1200v3rpl, S1200v3rpm, S1200v3rpo, S1200v3rps, S1400fp2, S1400fp4, S1400sp4, or S1400sp2)
- Navigate to Intel's support website and locate the firmware download page for that specific server board model
- Download the latest firmware update package (version 0006 for S1200v3 series or version 0005 for S1400 series)
- Review Intel's firmware update instructions in the firmware release notes or user guide
- Execute the firmware update using Intel® System Update Utility, Intel® Server Platform Services, or the appropriate BIOS flash utility provided
- Reboot the system as directed by the update utility
- Verify the installed firmware version matches the fixed release (0006 or 0005)
