Fedora 38 : python-jupyter-server (2023-88c411e973)

medium Nessus Plugin ID 181192



The remote Fedora host is missing one or more security updates.


The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-88c411e973 advisory.

- jupyter-server is the backend for Jupyter web applications. Improper cross-site credential checks on `/files/` URLs could allow exposure of certain file contents, or accessing files when opening untrusted files via Open image in new tab. This issue has been addressed in commit `87a49272728` which has been included in release `2.7.2`. Users are advised to upgrade. Users unable to upgrade may use the lower performance `--ContentsManager.files_handler_class=jupyter_server.files.handlers.FilesHandler`, which implements the correct checks. (CVE-2023-40170)

- jupyter-server is the backend for Jupyter web applications. Open Redirect Vulnerability. Maliciously crafted login links to known Jupyter Servers can cause successful login or an already logged-in session to be redirected to arbitrary sites, which should be restricted to Jupyter Server-served URLs. This issue has been addressed in commit `29036259` which is included in release 2.7.2. Users are advised to upgrade.
There are no known workarounds for this vulnerability. (CVE-2023-39968)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
