CVE-2023-51663

Advisory

Hail, a Python-based data analysis tool, uses OpenID Connect (OIDC) email addresses to verify user domains. However, users can change their email addresses, potentially gaining unauthorized access to resources. For instance, a user could create a Microsoft or Google account, change their email to [email protected], and then create a Hail Batch account in clusters under the example.org domain. While they can't access private data or impersonate others, they can run jobs and create Azure Tenants if they have the necessary access.

Vulnerability changelog

Hail is an open-source, general-purpose, Python-based data analysis tool with additional data types and methods for working with genomic data. Hail relies on OpenID Connect (OIDC) email addresses from ID tokens to verify the validity of a user's domain, but because users have the ability to change their email address, they could create accounts and use resources in clusters that they should not have access to. For example, a user could create a Microsoft or Google account and then change their email to `[email protected]`. This account can then be used to create a Hail Batch account in Hail Batch clusters whose organization domain is `example.org`. The attacker is not able to access private data or impersonate another user, but they would have the ability to run jobs if Hail Batch billing projects are enabled and create Azure Tenants if they have Azure Active Directory Administrator access. See CVE-2023-51663.
