CVE-2018-15380 — Cisco Hyperflex Hx Data Platform security vulnerability

High CVSS 8.8

A vulnerability in the cluster service manager of Cisco HyperFlex Software could allow an unauthenticated, adjacent attacker to execute commands as the root user. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by connecting to the cluster service manager and injecting commands into the bound process. A successful exploit could allow the attacker to run commands on the affected host as the root user. This vulnerability affects Cisco HyperFlex Software releases prior to 3.5(2a).

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.
