CVE-2018-12147 — Intel Converged Security Management Engine Firmware security vulnerability

High CVSS 7.2

Insufficient input validation in HECI subsystem in Intel(R) CSME before version 11.21.55, Intel® Server Platform Services before version 4.0 and Intel® Trusted Execution Engine Firmware before version 3.1.55 may allow a privileged user to potentially enable escalation of privileges via local access.

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
