DescriptionNVD
Missing integrity verification in the Triton inference handler in Amazon SageMaker Python SDK v2 before v2.257.2 and v3 before v3.8.0 might allow a remote authenticated actor to achieve code execution in inference containers via replacement of model artifacts in S3 with a specially crafted pickle payload that is deserialized without verification. This issue requires a remote authenticated actor with S3 write access to the model artifact path.
To remediate this issue, we recommend upgrading to Amazon SageMaker Python SDK v2.257.2 or v3.8.0 and rebuild any Triton models previously created with ModelBuilder using the updated SDK.
AnalysisAI
Remote authenticated actors with S3 write access can achieve code execution in Amazon SageMaker Triton inference containers by replacing model artifacts with malicious pickle payloads that are deserialized without integrity verification. Affected versions are SDK v2 before v2.257.2 and v3 before v3.8.0. …
