CVE-2022-28639 — Hpe Integrated Lights-Out 5 Firmware security vulnerability

High CVSS 8.8

A remote potential adjacent denial of service (DoS) and potential adjacent arbitrary code execution vulnerability that could potentially lead to a loss of confidentiality, integrity, and availability were discovered in HPE Integrated Lights-Out 5 (iLO 5) in Version: 2.71. Hewlett Packard Enterprise has provided updated firmware for HPE Integrated Lights-Out 5 (iLO 5) that addresses these security vulnerabilities.

Matched remediation archetype

Resource exhaustion and denial of service

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

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
