CVE-2022-1805 — When connecting to Amazon Workspaces, the SHA256 presented by AWS connection provisioner is not fully verified by Zero Clients

High CVSS 8.1

When connecting to Amazon Workspaces, the SHA256 presented by AWS connection provisioner is not fully verified by Zero Clients. The issue could be exploited by an adversary that places a MITM (Man in the Middle) between a zero client and AWS session provisioner in the network. This issue is only applicable when connecting to an Amazon Workspace from a PCoIP Zero Client.

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.
