Administrator-only user data disclosure via crafted API request

Published Nov 4, 2021 · Updated Nov 7, 2024

The web management interface returns security questions and answers for a crafted API request without sufficiently protecting those fields. Valid Administrator credentials are required, and the documented consequence is disclosure of application user information.
