CVE-2020-11016 — Intelmq Manager Project Intelmq Manager security vulnerability

Critical CVSS 9.1

IntelMQ Manager from version 1.1.0 and before version 2.1.1 has a vulnerability where the backend incorrectly handled messages given by user-input in the "send" functionality of the Inspect-tool of the Monitor component. An attacker with access to the IntelMQ Manager could possibly use this issue to execute arbitrary code with the privileges of the webserver. Version 2.1.1 fixes the vulnerability.

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.
