      "value": "When using IPAuthenticationProvider in ZooKeeper Admin Server there is a possibility of Authentication Bypass by Spoofing -- this only impacts IP based authentication implemented in ZooKeeper Admin Server. Default configuration of client's IP address detection in\u00a0IPAuthenticationProvider, which uses HTTP request headers, is weak\u00a0and allows an attacker to bypass authentication via spoofing client's IP address in request headers. Default configuration honors X-Forwarded-For HTTP header to read client's IP address. X-Forwarded-For request header is mainly used by proxy servers to identify the client and can be easily spoofed by an attacker pretending that the request comes from a different IP address. Admin Server commands, such as snapshot and restore arbitrarily can be executed on successful exploitation which could potentially lead to information leakage or service availability issues. Users are recommended to upgrade to version 3.9.3, which fixes this issue."

      "value": "Al utilizar IPAuthenticationProvider en el servidor de administraci\u00f3n de ZooKeeper, existe la posibilidad de omisi\u00f3n de autenticaci\u00f3n por suplantaci\u00f3n; esto solo afecta a la autenticaci\u00f3n basada en IP implementada en el servidor de administraci\u00f3n de ZooKeeper. La configuraci\u00f3n predeterminada de la detecci\u00f3n de la direcci\u00f3n IP del cliente en IPAuthenticationProvider, que utiliza encabezados de solicitud HTTP, es d\u00e9bil y permite a un atacante omitir la autenticaci\u00f3n mediante la suplantaci\u00f3n de la direcci\u00f3n IP del cliente en los encabezados de solicitud. La configuraci\u00f3n predeterminada respeta el encabezado HTTP X-Forwarded-For para leer la direcci\u00f3n IP del cliente. El encabezado de solicitud X-Forwarded-For es utilizado principalmente por servidores proxy para identificar al cliente y puede ser f\u00e1cilmente suplantado por un atacante que pretenda que la solicitud proviene de una direcci\u00f3n IP diferente. Los comandos del servidor de administraci\u00f3n, como instant\u00e1nea y restauraci\u00f3n, se pueden ejecutar arbitrariamente en caso de explotaci\u00f3n exitosa, lo que podr\u00eda provocar fugas de informaci\u00f3n o problemas de disponibilidad del servicio. Se recomienda a los usuarios que actualicen a la versi\u00f3n 3.9.3, que soluciona este problema."
