CVE-2022-28636 — Hpe Integrated Lights-Out 5 Firmware security vulnerability

High CVSS 7.4

A potential local arbitrary code execution and a local denial of service (DoS) vulnerability within an isolated process were discovered in HPE Integrated Lights-Out 5 (iLO 5) firmware version(s): Prior to 2.71. An unprivileged user could locally exploit this vulnerability to potentially execute arbitrary code in an isolated process resulting in a complete loss of confidentiality, integrity, and availability within that process. In addition, an unprivileged user could exploit a denial of service (DoS) vulnerability in an isolated process resulting in a complete loss of availability within that process. A successful attack depends on conditions beyond the attackers control. HPE has provided a firmware update to resolve this vulnerability in HPE Integrated Lights-Out 5 (iLO 5).

Matched remediation archetype

Command, code, expression, and template injection

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

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
