CVE-2024-34072

Code execution via default pickle-enabled NumPy loading

Published May 3, 2024 · Updated Aug 2, 2024

Unsafe deserialization in Amazon SageMaker Python SDK before 2.218.0 allows attackers to execute code through a crafted NumPy object array. NumpyDeserializer passes NPY and NPZ stream data to numpy.load with allow_pickle enabled by default, causing embedded pickle objects to execute during loading. Exploitation requires an application or user to deserialize an untrusted or tampered object array and grants code execution with the consuming process's privileges, including data access, modification, or service interruption.
