When Tornado's ``multipart/form-data`` parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. All versions of Tornado prior to 6.5.0 are affected. The vulnerable parser is enabled by default. Upgrade to Tornado version 6.50 to receive a patch. As a workaround, risk can be mitigated by blocking `Content-Type: multipart/form-data` in a proxy."},{"lang":"es","value":"Tornado es un framework web de Python y una librería de redes asíncronas. Cuando el analizador ``multipart/form-data`` de Tornado detecta ciertos errores, registra una advertencia, pero continúa intentando analizar el resto de los datos. Esto permite a atacantes remotos generar un volumen extremadamente alto de registros, lo que constituye un ataque de denegación de servicio (DoS). Este DoS se ve agravado por el hecho de que el subsistema de registro es síncrono. Todas las versiones de Tornado anteriores a la 6.5.0 están afectadas. El analizador vulnerable está habilitado por defecto. Actualice a la versión 6.50 de Tornado para recibir un parche.
