CVE-2019-6446
CRITICALNumPy < 1.16.3 - Remote Code Execution via Unsafe Pickle Deserialization
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2019-6446. PoCs published by RayScri.
AI-analyzed exploit summary This PoC demonstrates a deserialization vulnerability in NumPy (CVE-2019-6446) by crafting a malicious pickle file that executes arbitrary commands (e.g., 'whoami') when loaded via `numpy.ma.core.load()`. The exploit leverages Python's `pickle` module and the `__reduce__` method to achieve RCE.
Description
An issue was discovered in NumPy before 1.16.3. It uses the pickle Python module unsafely, which allows remote attackers to execute arbitrary code via a crafted serialized object, as demonstrated by a numpy.load call. NOTE: third parties dispute this issue because it is a behavior that might have legitimate applications in (for example) loading serialized Python object arrays from trusted and authenticated sources.
