Authenticated code execution via unsafe model deserialization
Published Sep 12, 2024 · Updated Sep 12, 2024
Deserialization in MindsDB 23.10.3.0 and later allows remote authenticated users to execute arbitrary code through a malicious inhouse model. ModelWrapperUnsafe.describe passes stored model state from the BYOM handler directly to pickle.loads, which invokes attacker-controlled reduction logic. Exploitation requires the BYOM engine to be changed from the default venv mode to inhouse mode and a separate user to run a describe query or open the model in the UI.
