Executive brief
Velociraptor is a digital forensics and incident response platform that can integrate with external identity providers (OIDC) for user authentication. When configured this way, it trusts the email address claim from the identity provider to identify users. However, some identity providers allow users to change their email address without verifying it, enabling attackers to impersonate other users and gain unauthorized access to Velociraptor.
Technical details
The vulnerability is an authentication bypass in Velociraptor's OIDC integration. The root cause is that Velociraptor uses the email claim from the OIDC token as a username without verifying the email address through the "email_verified" claim. Some OIDC providers do not enforce email verification or allow users to change their email claim without validation. An attacker with access to an OIDC IdP can set their email address to match another user's email, allowing them to authenticate as that user. Attack vector is network-based and requires only that the attacker has valid access to the shared OIDC identity provider. The fix is to update Velociraptor to version 0.77.2 or later, which addresses this vulnerability.
