There are two issues with this functionality (when using SecurityAwareZkACLProvider type of ACL provider e.g. SaslZkACLProvider). Firstly, access to the security configuration can be leaked to users other than the solr super user. Secondly, malicious users can exploit this leaked configuration for privilege escalation to further expose/modify private data and/or disrupt operations in the Solr cluster. The vulnerability is fixed from Apache Solr 6.6.1 onwards."}, {"lang": "es", "value": "El plugin Kerberos de Apache Solr puede configurarse para emplear tokens de delegaci\u00f3n, lo que permite que una aplicaci\u00f3n reutilice la autenticaci\u00f3n de un usuario final o de otra aplicaci\u00f3n. Hay dos problemas con esta funcionalidad (al emplear el tipo SecurityAwareZkACLProvider del proveedor de listas de control de acceso, como SaslZkACLProvider). En primer lugar, el acceso a la configuraci\u00f3n de seguridad puede filtrarse a otros usuarios distintos al superusuario de solr. En segundo lugar, los usuarios maliciosos pueden explotar esta configuraci\u00f3n filtrada para escalar privilegios para exponer/modificar aun m\u00e1s los datos privados y/o las operaciones de interrupci\u00f3n en el cl\u00faster de Solr.
