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 Intel(R) In-Band Manageability software before version 2.13.0 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 Intel In-Band Manageability software before version 2.13.0 allows a privileged user to potentially escalate privileges via local access. The vulnerability stems from insufficient validation of input parameters that could be manipulated to gain higher-level system privileges.

MitigationUpgrade Intel In-Band Manageability software to version 2.13.0 or later to address the input validation vulnerability.

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. Verify Intel In-Band Manageability is installed
    Check installed programs or running services for Intel In-Band Manageability, Intel AMT, or related Intel management software components
    Affected if The software is present on the system and version cannot be determined or is found to be 2.13.0 or lower
  2. Determine installed version
    Use system inventory, installed software listing, or check the Intel In-Band Manageability service properties to locate the version number
    Affected if Installed version is 2.13.0 or any version lower than 2.13.0
  3. Confirm the management service is active
    Check if the Intel In-Band Manageability service or Intel AMT service is currently running on the system
    Affected if The service is running and the software version is 2.13.0 or lower
  4. Identify privileged user context
    Review user accounts that have access to the In-Band Manageability interface or local system privileges that could interact with this software
    Affected if Privileged users exist on the system where the vulnerable software version is installed and running

The environment is affected if Intel In-Band Manageability software version 2.13.0 or lower is installed and running, allowing a privileged local user to potentially escalate privileges through improper input validation.

Upgrade available Upgrade to a release after 2.13.0
Interim mitigation

Upgrade Intel In-Band Manageability software to version 2.13.0 or later to address the input validation vulnerability.

Recommended fix High confidence

Version 2.13.0 or later of Intel In-Band Manageability software

  1. Locate the Intel In-Band Manageability software installation on the system
  2. Identify the current installed version (typically found in software inventory, about dialog, or version file)
  3. Navigate to the Intel support website or download page for In-Band Manageability software
  4. Download version 2.13.0 or any version released after the fixed version 2.13.0
  5. Follow Intel's standard installation procedures for In-Band Manageability software (typically requires administrative privileges)
  6. Restart any affected services if prompted by the installer
  7. Verify the installed version reflects the upgrade
Caveat Consult Intel release notes for any configuration or compatibility changes between versions; minor version upgrades typically retain backward compatibility
