Last updated on: 2025-10-03

Assigner: WSO2 LLC

Description
An authentication bypass vulnerability exists in multiple WSO2 products when FIDO authentication is enabled. When a user account is deleted, the system does not automatically remove associated FIDO registration data. If a new user account is later created using the same username, the system may associate the new account with the previously registered FIDO device. This flaw may allow a previously deleted user to authenticate using their FIDO credentials and impersonate the newly created user, resulting in unauthorized access. The vulnerability applies only to deployments that utilize FIDO-based authentication.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is an authentication bypass issue in multiple WSO2 products when FIDO authentication is enabled. When a user account is deleted, the system does not remove the associated FIDO registration data. If a new user account is created later with the same username, the system may link the new account to the old FIDO device, allowing the previously deleted user to authenticate and impersonate the new user.


How can this vulnerability impact me? :

This vulnerability can allow unauthorized access by enabling a previously deleted user to authenticate using their old FIDO credentials and impersonate a newly created user with the same username. This could lead to unauthorized access to the new user's account and potentially sensitive information.


What immediate steps should I take to mitigate this vulnerability?

To mitigate this vulnerability, ensure that when a user account is deleted, all associated FIDO registration data is also removed to prevent reuse of FIDO credentials by a new user with the same username. Additionally, review and restrict FIDO-based authentication usage and monitor user account deletions to verify proper cleanup of authentication data.
