Descriptions
Apache Solr's Kerberos plugin can be configured to use delegation tokens, which allows an application to reuse the authentication of an end-user or another application. 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.
El plugin Kerberos de Apache Solr puede configurarse para emplear tokens de delegación, lo que permite que una aplicación reutilice la autenticación de un usuario final o de otra aplicación. 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 configuración de seguridad puede filtrarse a otros usuarios distintos al superusuario de solr. En segundo lugar, los usuarios maliciosos pueden explotar esta configuración filtrada para escalar privilegios para exponer/modificar aun más los datos privados y/o las operaciones de interrupción en el clúster de Solr. Esta vulnerabilidad se ha solucionado desde la versión 6.6.1 de Solr.
