CVE-2024-43805: HTML injection in Jupyter Notebook and JupyterLab leading to DOM Clobbering
Impact
The vulnerability depends on user interaction by opening a malicious notebook with Markdown cells, or Markdown file using JupyterLab preview feature.
A malicious user can access any data that the attacked user has access to as well as perform arbitrary requests acting as the attacked user.
Patches
JupyterLab v3.6.8, v4.2.5 and Jupyter Notebook v7.2.2 were patched.
Workarounds
There is no workaround for the underlying DOM Clobbering susceptibility. However, select plugins can be disabled on deployments which cannot update in a timely fashion to minimise the risk. These are: - @jupyterlab/mathjax-extension:plugin - users will loose ability to preview mathematical equations - @jupyterlab/markdownviewer-extension:plugin - users will loose ability to open Markdown previews - @jupyterlab/mathjax2-extension:plugin (if installed with optional jupyterlab-mathjax2 package) - an older version of the mathjax plugin for JupyterLab 4.x
To disable these extensions run:
bash jupyter labextension disable @jupyterlab/markdownviewer-extension:plugin jupyter labextension disable @jupyterlab/mathjax-extension:plugin jupyter labextension disable @jupyterlab/mathjax2-extension:plugin
To confirm that the plugins were disabled run:
bash jupyter labextension list
References
None
Notes
This change has a potential to break rendering of some markdown. There is a setting in Sanitizer which allows to revert to the previous sanitizer settings (allowNamedProperties).
Other sources
jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. This vulnerability depends on user interaction by opening a malicious notebook with Markdown cells, or Markdown file using JupyterLab preview feature. A malicious user can access any data that the attacked user has access to as well as perform arbitrary requests acting as the attacked user. JupyterLab v3.6.8, v4.2.5 and Jupyter Notebook v7.2.2 have been patched to resolve this issue. Users are advised to upgrade. There is no workaround for the underlying DOM Clobbering susceptibility.
