CVE-2024-20444 — Cisco Nexus Dashboard Fabric Controller security vulnerability

Medium CVSS 5.5

A vulnerability in Cisco Nexus Dashboard Fabric Controller (NDFC), formerly Cisco Data Center Network Manager (DCNM), could allow an authenticated, remote attacker with network-admin privileges to perform a command injection attack against an affected device.   This vulnerability is due to insufficient validation of command arguments. An attacker could exploit this vulnerability by submitting crafted command arguments to a specific REST API endpoint. A successful exploit could allow the attacker to overwrite sensitive files or crash a specific container, which would restart on its own, causing a low-impact denial of service (DoS) condition.

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.
