CVE-2021-43811
Code injection via unsafe YAML loading
Impact
### Impact 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. ### Patches The issue is fixed in version 2.3.24 and above by #964. ### For more information If you have any questions or comments about this advisory: * Open an issue in [awslabs/sockeye](https://github.com/awslabs/sockeye) * Email us at [sockeye-dev](mailto:sockeye-dev@amazon.com) ### Attribution This vulnerability was reported by Masatoshi Yoshizawa of yamory Security Team.
