Insufficient Nonce Validation in Eclipse Milo Client

Impact

Credential replay affecting those connected to a server when all 3 of the following conditions are met:

• SecurityPolicy is None
• using username/password or X509-based authentication
• the server has a defect causing it to send null/empty or zeroed nonces

Patches

The problem has been patched in version 0.3.6. A more relaxed treatment of validation as agreed upon by the OPC UA Security Working Group is implemented in version 0.3.7.

Workarounds

Do not use username/password or X509-based authentication with SecurityPolicy of None.
