CVSS: 8.1EPSS: 0%CPEs: 1EXPL: 0CVE-2024-37300 – Globus `identity_provider` restriction ignored when used with `allow_all` in JupyterHub 5.0
https://notcve.org/view.php?id=CVE-2024-37300
OAuthenticator is software that allows OAuth2 identity providers to be plugged in and used with JupyterHub. JupyterHub < 5.0, when used with `GlobusOAuthenticator`, could be configured to allow all users from a particular institution only. This worked fine prior to JupyterHub 5.0, because `allow_all` did not take precedence over `identity_provider`. Since JupyterHub 5.0, `allow_all` does take precedence over `identity_provider`. On a hub with the same config, now all users will be allowed to login, regardless of `identity_provider`. • https://github.com/jupyterhub/oauthenticator/commit/d1aea05fa89f2beae15ab0fa0b0d071030f79654 https://github.com/jupyterhub/oauthenticator/security/advisories/GHSA-gprj-3p75-f996 https://jupyterhub.readthedocs.io/en/stable/howto/upgrading-v5.html#authenticator-allow-all-and-allow-existing-users • CWE-863: Incorrect Authorization •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2024-29033 – GoogleOAuthenticator.hosted_domain incorrectly verifies membership of an Google organization/workspace
https://notcve.org/view.php?id=CVE-2024-29033
OAuthenticator provides plugins for JupyterHub to use common OAuth providers, as well as base classes for writing one's own Authenticators with any OAuth 2.0 provider. `GoogleOAuthenticator.hosted_domain` is used to restrict what Google accounts can be authorized access to a JupyterHub. The restriction is intented to be to Google accounts part of one or more Google organization verified to control specified domain(s). Prior to version 16.3.0, the actual restriction has been to Google accounts with emails ending with the domain. Such accounts could have been created by anyone which at one time was able to read an email associated with the domain. • https://github.com/jupyterhub/oauthenticator/commit/5246b09675501b09fb6ed64022099b7644812f60 https://github.com/jupyterhub/oauthenticator/security/advisories/GHSA-55m3-44xf-hg4h https://trufflesecurity.com/blog/google-oauth-is-broken-sort-of • CWE-285: Improper Authorization •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2022-31027 – Authorization Bypass Through User-Controlled Key when using CILogonOAuthenticator in oauthenticator
https://notcve.org/view.php?id=CVE-2022-31027
OAuthenticator is an OAuth token library for the JupyerHub login handler. CILogonOAuthenticator is provided by the OAuthenticator package, and lets users log in to a JupyterHub via CILogon. This is primarily used to restrict a JupyterHub only to users of a given institute. The allowed_idps configuration trait of CILogonOAuthenticator is documented to be a list of domains that indicate the institutions whose users are authorized to access this JupyterHub. This authorization is validated by ensuring that the *email* field provided to us by CILogon has a *domain* that matches one of the domains listed in `allowed_idps`.If `allowed_idps` contains `berkeley.edu`, you might expect only users with valid current credentials provided by University of California, Berkeley to be able to access the JupyterHub. • https://github.com/jupyterhub/oauthenticator/security/advisories/GHSA-r7v4-jwx9-wx43 • CWE-639: Authorization Bypass Through User-Controlled Key •
CVSS: 6.3EPSS: 0%CPEs: 1EXPL: 0CVE-2020-26250 – Base class whitelist configuration ignored in OAuthenticator
https://notcve.org/view.php?id=CVE-2020-26250
OAuthenticator is an OAuth login mechanism for JupyterHub. In oauthenticator from version 0.12.0 and before 0.12.2, the deprecated (in jupyterhub 1.2) configuration `Authenticator.whitelist`, which should be transparently mapped to `Authenticator.allowed_users` with a warning, is instead ignored by OAuthenticator classes, resulting in the same behavior as if this configuration has not been set. If this is the only mechanism of authorization restriction (i.e. no group or team restrictions in configuration) then all authenticated users will be allowed. Provider-based restrictions, including deprecated values such as `GitHubOAuthenticator.org_whitelist` are **not** affected. All users of OAuthenticator 0.12.0 and 0.12.1 with JupyterHub 1.2 (JupyterHub Helm chart 0.10.0-0.10.5) who use the `admin.whitelist.users` configuration in the jupyterhub helm chart or the `c.Authenticator.whitelist` configuration directly. • https://github.com/jupyterhub/oauthenticator/blob/master/docs/source/changelog.md#0122---2020-11-30 https://github.com/jupyterhub/oauthenticator/commit/a4aac191c16cf6281f3d346615aefa75702b02d7 https://github.com/jupyterhub/oauthenticator/security/advisories/GHSA-384w-5v3f-q499 https://jupyterhub.readthedocs.io/en/1.2.2/getting-started/authenticators-users-basics.html#add-or-remove-users-from-the-hub • CWE-863: Incorrect Authorization •
