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 the BMC firmware for Intel(R) Server Board M10JNP2SB before version EFI BIOS 7215, BMC 8100.01.08 may allow an unauthenticated user to potentially enable an 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 confidence

This vulnerability in Intel Server Board M10JNP2SB BMC firmware involves improper input validation that allows an unauthenticated attacker with adjacent network access to potentially escalate privileges. The issue affects both EFI BIOS (versions before 7215) and BMC (versions before 8100.01.08) components.

MitigationApply the vendor-provided firmware updates (EFI BIOS 7215 and BMC 8100.01.08 or later) following Intel's recommended update procedures, and restrict physical/adjacent network access to the server 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 checks

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

  1. Confirm Intel Server Board M10JNP2SB is in use
    Use IPMI command 'ipmitool chassis status' or access BIOS setup screen to identify the server board model number
    Affected if The system is an Intel Server Board M10JNP2SB
  2. Check EFI BIOS version
    Run 'ipmitool raw' command or view BIOS setup screen to retrieve the EFI BIOS version; compare numerically against version 7215
    Affected if EFI BIOS version is numerically less than 7215
  3. Check BMC firmware version
    Execute 'ipmitool mc info' command or log into BMC web interface to obtain firmware version; compare against 8100.01.08
    Affected if BMC firmware version is earlier than 8100.01.08
  4. Determine BMC network accessibility
    Review network configuration and firewall rules to check if the BMC management interface is exposed to adjacent network segments
    Affected if BMC is reachable from adjacent or untrusted network segments

System is affected if it is an Intel Server Board M10JNP2SB with EFI BIOS version below 7215 OR BMC firmware version below 8100.01.08, especially when the BMC has adjacent network accessibility

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the vendor-provided firmware updates (EFI BIOS 7215 and BMC 8100.01.08 or later) following Intel's recommended update procedures, and restrict physical/adjacent network access to the server infrastructure.

Recommended fix High confidence

EFI BIOS 7215 and BMC 8100.01.08

  1. 1. Navigate to Intel's support website and download the EFI BIOS version 7215 and BMC firmware version 8100.01.08 for the Intel Server Board M10JNP2SB
  2. 2. Verify the current firmware versions by accessing the BMC web interface or using IPMI commands
  3. 3. Apply the BMC firmware update 8100.01.08 through the BMC web interface, IPMI firmware update command, or Intel System Update Utility
  4. 4. After BMC update completes, apply the EFI BIOS version 7215 update through the BMC web interface, Intel System Update Utility, or BIOS flash utility
  5. 5. Reboot the system to ensure both firmware updates take effect
  6. 6. Verify the installed versions match the target versions (EFI BIOS 7215 and BMC 8100.01.08)
