Bypassing .NET Serialization Binders

A .NET SerializationBinder that validates type names as strings, or returns null when it cannot resolve one, can be bypassed: BinaryFormatter then falls back to its own resolver. An assembly-qualified name parsed differently by binder and runtime restores blocked gadget types, giving remote code execution in DevExpress (CVE-2022-28684) and Exchange (CVE-2022-23277).
