CVE-2020-12040 — Baxter Sigma Spectrum Infusion System Firmware security vulnerability

Critical CVSS 9.8

Sigma Spectrum Infusion System v's6.x (model 35700BAX) and Baxter Spectrum Infusion System Version(s) 8.x (model 35700BAX2) at the application layer uses an unauthenticated clear-text communication channel to send and receive system status and operational data. This could allow an attacker that has circumvented network security measures to view sensitive non-private data or to perform a man-in-the-middle attack.

Matched remediation archetype

Cryptography, certificate, signature, and channel validation

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

Check exposure

  • Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
  • Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
  • Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.

Remediate safely

  • Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
  • Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
  • Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
