CVE intelligence and bounded remediation

CVE-2019-1634 — Cisco Unified Computing System security vulnerability

High CVSS 9

A vulnerability in the Intelligent Platform Management Interface (IPMI) of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges on the underlying operating system (OS). The vulnerability is due to insufficient input validation of user-supplied commands. An attacker who has administrator privileges and access to the network where the IPMI resides could exploit this vulnerability by submitting crafted input to the affected commands. A successful exploit could allow the attacker to gain root privileges on the affected device.

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.
