Authentication bypass via unchecked registration POST
Published Aug 11, 2023 · Updated Oct 9, 2024
Authentication bypass in Open-Falcon Dashboard 0.2.0 allows remote attackers to create an account through the registration endpoint. The POST branch in auth_register processes account fields without enforcing the signup_disable setting that blocks registration. No prior account is required; the resulting dashboard account can view, modify, and add monitored data.
