Описание

JupyterLab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. From 4.0.0 to 4.5.6, the allow-list of extensions that can be installed from PyPI Extension Manager (allowed_extensions_uris) is not correctly enforced by JupyterLab. The PyPI Extension Manager was not contained to packages listed on the default PyPI index. This vulnerability is fixed in 4.5.7.

A flaw was found in JupyterLab, an extensible environment for interactive computing. The PyPI Extension Manager, responsible for installing extensions, failed to properly enforce its allow-list of approved extensions. This vulnerability allowed for the installation of unauthorized extensions from sources outside the default PyPI index. Exploitation of this flaw could lead to arbitrary code execution and significant system compromise.

Отчет

This Important flaw in JupyterLab, as utilized in Red Hat OpenShift AI and Migration Toolkit for Applications, stems from the PyPI Extension Manager's failure to enforce its extension allow-list. This enables the installation of unauthorized extensions from external sources, potentially leading to arbitrary code execution and significant system compromise within the JupyterLab environment.

Меры по смягчению последствий

Upgrade JupyterLab to version 4.5.7 or later. Set the JupyterLab extension manager to read-only mode to prevent users from installing unauthorized extensions. Note: configuring a PyPI proxy with an allow list of packages is not sufficient to protect against this vulnerability.
