CVSS: 7.2EPSS: 0%CPEs: 2EXPL: 0CVE-2024-41942 – JupyterHub has a privilege escalation vulnerability with the `admin:users` scope
https://notcve.org/view.php?id=CVE-2024-41942
JupyterHub is software that allows one to create a multi-user server for Jupyter notebooks. Prior to versions 4.1.6 and 5.1.0, if a user is granted the `admin:users` scope, they may escalate their own privileges by making themselves a full admin user. The impact is relatively small in that `admin:users` is already an extremely privileged scope only granted to trusted users. In effect, `admin:users` is equivalent to `admin=True`, which is not intended. Note that the change here only prevents escalation to the built-in JupyterHub admin role that has unrestricted permissions. It does not prevent users with e.g. • https://github.com/jupyterhub/jupyterhub/commit/99e2720b0fc626cbeeca3c6337f917fdacfaa428 https://github.com/jupyterhub/jupyterhub/commit/ff2db557a85b6980f90c3158634bf924063ab8ba https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-9x4q-3gxw-849f • CWE-274: Improper Handling of Insufficient Privileges •
CVSS: 8.1EPSS: 0%CPEs: 1EXPL: 0CVE-2024-28233 – XSS in JupyterHub via Self-XSS leveraged by Cookie Tossing
https://notcve.org/view.php?id=CVE-2024-28233
JupyterHub is an open source multi-user server for Jupyter notebooks. By tricking a user into visiting a malicious subdomain, the attacker can achieve an XSS directly affecting the former's session. More precisely, in the context of JupyterHub, this XSS could achieve full access to JupyterHub API and user's single-user server. The affected configurations are single-origin JupyterHub deployments and JupyterHub deployments with user-controlled applications running on subdomains or peer subdomains of either the Hub or a single-user server. This vulnerability is fixed in 4.1.0. • https://github.com/jupyterhub/jupyterhub/commit/e2798a088f5ad45340fe79cdf1386198e664f77f https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-7r3h-4ph8-w38g • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-352: Cross-Site Request Forgery (CSRF) CWE-565: Reliance on Cookies without Validation and Integrity Checking •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-41247 – incomplete logout in JupyterHub
https://notcve.org/view.php?id=CVE-2021-41247
JupyterHub is an open source multi-user server for Jupyter notebooks. In affected versions users who have multiple JupyterLab tabs open in the same browser session, may see incomplete logout from the single-user server, as fresh credentials (for the single-user server only, not the Hub) reinstated after logout, if another active JupyterLab session is open while the logout takes place. Upgrade to JupyterHub 1.5. For distributed deployments, it is jupyterhub in the _user_ environment that needs patching. There are no patches necessary in the Hub environment. • https://github.com/jupyterhub/jupyterhub/commit/5ac9e7f73a6e1020ffddc40321fc53336829fe27 https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-cw7p-q79f-m2v7 • CWE-613: Insufficient Session Expiration •

https://notcve.org/view.php?id=CVE-2020-36191
JupyterHub 1.1.0 allows CSRF in the admin panel via a request that lacks an _xsrf field, as demonstrated by a /hub/api/user request (to add or remove a user account). JupyterHub versión 1.1.0, permite un ataque de tipo CSRF en el panel de administración por medio de una petición que carece de un campo _xsrf, como es demostrado por una petición /hub/api/user (para agregar o eliminar una cuenta de usuario). • https://github.com/jupyterhub/jupyterhub/issues/3304 https://github.com/jupyterhub/jupyterhub/releases • CWE-352: Cross-Site Request Forgery (CSRF) •
