In version 10.0.11 and prior, the WebAuthn authentication implementation does not store the challenge on the server side. Instead, the challenge is returned to the client and accepted back from the client request body during verification. This violates the WebAuthn specification (W3C Web Authentication Level 2, §13.4.3) and allows an attacker who has obtained a valid WebAuthn assertion (e.g., via XSS, MitM, or log exposure) to replay it indefinitely, completely bypassing the second-factor authentication. No known patches are available."},{"lang":"es","value":"OneUptime es una solución para monitorear y gestionar servicios en línea. En la versión 10.0.11 y anteriores, la implementación de autenticación WebAuthn no almacena el desafío en el lado del servidor. En su lugar, el desafío se devuelve al cliente y se acepta de nuevo desde el cuerpo de la solicitud del cliente durante la verificación. Esto viola la especificación WebAuthn (W3C Web Authentication Level 2, §13.4.3) y permite a un atacante que ha obtenido una aserción WebAuthn válida (por ejemplo, a través de XSS, MitM o exposición de registros) reproducirla indefinidamente, eludiendo completamente la autenticación de segundo factor.
