Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-354

Proper validation of integrity check values is required for reliable tamper detection, directly reducing undetected modification risks.

addresses: CWE-354

Requires validation of integrity check values on every resolution response, directly mitigating tampered or corrupted DNS data.

addresses: CWE-354

Control mandates proper validation of integrity values (checksums) on prepared data, making flawed validation of those checks ineffective for attackers.

addresses: CWE-354

Requires use of proper integrity verification tools, reducing the chance an incorrect check value is accepted.

addresses: CWE-354

Requires proper validation of integrity mechanisms, directly mitigating flawed check-value handling.

NVD Description

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.
