Details

The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications like Jupyter notebook, JupyterLab, and Voila. In Jupyter Server before version 1.1.1, an open redirect vulnerability could cause the jupyter server to redirect the browser to a different malicious website. All jupyter servers running without a base_url prefix are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may appear safe, but ultimately redirect to a spoofed server on the public internet. This same vulnerability was patched in upstream notebook v5.7.8. This is fixed in jupyter_server 1.1.1. If upgrade is not available, a workaround can be to run your server on a url prefix: "jupyter server --ServerApp.base_url=/jupyter/".

Summary

Jupyter Server open redirect vulnerability

Details

Impact

What kind of vulnerability is it? Who is impacted?

Open redirect vulnerability - a maliciously crafted link to a jupyter server could redirect the browser to a different website.

All jupyter servers running without a base_url prefix are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may appear safe, but ultimately redirect to a spoofed server on the public internet. This same vulnerability was patched in upstream notebook v5.7.8.

Patches

Has the problem been patched? What versions should users upgrade to?

Patched in jupyter_server 1.1.1. If upgrade is not available, a workaround can be to run your server on a url prefix:

jupyter server --ServerApp.base_url=/jupyter/

  "details": "### Impact\n_What kind of vulnerability is it? Who is impacted?_\n\nOpen redirect vulnerability - a maliciously crafted link to a jupyter server could redirect the browser to a different website.\n\nAll jupyter servers running without a base_url prefix are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may *appear* safe, but ultimately redirect to a spoofed server on the public internet. This same vulnerability was patched in upstream notebook v5.7.8.\n\n### Patches\n\n_Has the problem been patched? What versions should users upgrade to?_\n\nPatched in jupyter_server 1.1.1. If upgrade is not available, a workaround can be to run your server on a url prefix:\n\n```\njupyter server --ServerApp.base_url=/jupyter/\n```\n\n### References\n\n[OWASP page on open redirects](https://cheatsheetseries.owasp.org/cheatsheets/Unvalidated_Redirects_and_Forwards_Cheat_Sheet.html)\n\n### For more information\n\nIf you have any questions or comments about this advisory, or vulnerabilities to report, please email our security list [security@ipython.org](mailto:security@ipython.org).\n\nCredit: Yaniv Nizry from CxSCA group at Checkmarx",
