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 · unedited
Improper input validation in UEFI firmware for some Intel(R) Server S2600BPBR 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 · moderate confidence

Improper input validation in UEFI firmware on Intel Server S2600BPBR allows a privileged local user to potentially escalate privileges. The vulnerability stems from insufficient validation of input data within the UEFI firmware component, which could be exploited to gain elevated system privileges.

MitigationApply the latest UEFI firmware update from Intel for the S2600BPBR server board. Verify that firmware update paths are secured and restrict local administrative access to trusted personnel only.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the server board model
    Run command 'dmidecode -s baseboard-product-name' or check BIOS/UEFI setup screen to confirm the exact model number is S2600BPBR
    Affected if Model is S2600BPBR and the UEFI firmware has not been updated to the fixed version
  2. Check the installed UEFI firmware version
    Access UEFI setup (press F2 during POST), navigate to 'UEFI BIOS Version' or 'Firmware Version' under Main or Advanced tab, or use 'dmidecode -s bios-version' from OS
    Affected if UEFI firmware version is older than the latest Intel-published version for this board
  3. Verify local privileged user access controls
    Review local user accounts with administrative or root privileges using 'net user' (Windows) or 'cat /etc/passwd' and check sudoers (Linux), and verify physical access is restricted to trusted personnel only
    Affected if Multiple untrusted local users have administrative privileges or physical console access is uncontrolled
  4. Inspect UEFI secure boot configuration
    Enter UEFI setup, navigate to 'Secure Boot' or 'Boot' settings and verify whether Secure Boot is enabled and configured with trusted signatures
    Affected if Secure Boot is disabled or has non-default configurations allowing unauthenticated firmware components
  5. Check UEFI variable store for unauthorized modifications
    From Linux, run 'efivar -l' to list UEFI variables, or from Windows use 'bcdedit /enum firmware' to review boot entries; look for unexpected custom entries
    Affected if Unknown or unauthorized UEFI boot entries or variable modifications are present

A user is affected if the system is an Intel S2600BPBR running UEFI firmware versions prior to the latest Intel update, and untrusted local users have privileged access or physical console access to the server.
