CVE-2021-43811
HIGHSockeye < 2.3.24 - Remote Code Execution via Unsafe YAML Loading
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2021-43811. PoCs published by s-index.
AI-analyzed exploit summary This PoC demonstrates a YAML deserialization vulnerability in Sockeye (CVE-2021-43811), where unsafe YAML loading allows arbitrary code execution via a malicious config file. The exploit uses Python's YAML parser to trigger command execution (e.g., `cat /etc/passwd`).
Description
Sockeye is an open-source sequence-to-sequence framework for Neural Machine Translation built on PyTorch. Sockeye uses YAML to store model and data configurations on disk. Versions below 2.3.24 use unsafe YAML loading, which can be made to execute arbitrary code embedded in config files. An attacker can add malicious code to the config file of a trained model and attempt to convince users to download and run it. If users run the model, the embedded code will run locally. The issue is fixed in version 2.3.24.
