Authorization Bypass Through User-Controlled Key

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. However, CILogonOAuthenticator does *not* verify which provider is used by the user to login, only the email address provided. So a user can login with a GitHub account that has email set to `<something>@berkeley.edu`, and that will be treated exactly the same as someone logging in using the UC Berkeley official Identity Provider. The patch fixing this issue makes a *breaking change* in how `allowed_idps` is interpreted. It's no longer a list of domains, but configuration representing the `EntityID` of the IdPs that are allowed, picked from the [list maintained by CILogon](https://cilogon.org/idplist/). Users are advised to upgrade.Show less

An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data.Show less

An Improper Access Control vulnerability in the Juniper Networks Paragon Active Assurance Control Center allows an unauthenticated attacker to leverage a crafted URL to generate PDF reports, potentially containing sensitive configuration information. A feature was introduced in version 3.1 of the Paragon Active Assurance Control Center which allows users to selective share account data using a unique identifier. Knowing the proper format of the URL and the identifier of an existing object in an application it is possible to get access to that object without being logged in, even if the object is not shared, resulting in the opportunity for malicious exfiltration of user data. Note that the Paragon Active Assurance Control Center SaaS offering is not affected by this issue. This issue affects Juniper Networks Paragon Active Assurance version 3.1.0.Show less
