NewCVE-2024-42512 (opens in a new tab)How to fix?
Upgrade OPCFoundation.NetStandard.Opc.Ua to version 1.5.374.158 or higher.
Overview
OPCFoundation.NetStandard.Opc.Ua is a package that contains the OPC UA reference implementation and is targeting the .NET Standard Library.
Affected versions of this package are vulnerable to Timing Attack when using the deprecated Basic128Rsa15 security policy (disabled by default). This allows an attacker to infer information that enables an authentication bypass.
Upgrading or applying the patch to detect and close connections using Basic128Rsa15 will interrupt those connections if they are already in use.
