Descriptions

Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.

Ocurre una ejecución remota de código en Apache Solr en versiones anteriores a la 7.1 con Apache Lucene en versiones anteriores a la 7.1 explotando XXE junto con el uso de un comando add-listener de la API de configuración para alcanzar la clase RunExecutableListener. Elasticsearch, a pesar de que emplea Lucene, NO es vulnerable a esto. Es destacable que la vulnerabilidad de XML external entity expansion ocurre en el analizador sintáctico de consulta de XML que está disponible, por defecto, para cualquier petición de consulta con parámetros deftype=xmlparser y puede ser explotado para subir datos maliciosos al manipulador de peticiones /upload o como XXE ciego empleando un contenedor ftp para leer archivos locales arbitrarios del servidor Solr. También hay que tener en cuenta el hecho de que la segunda vulnerabilidad está relacionada con la ejecución remota de código empleando la clase RunExecutableListener disponible en todas las versiones afectadas de Solr.

It was found that Apache Lucene would accept an object from an unauthenticated user that could be manipulated through subsequent post requests. An attacker could use this flaw to assemble an object that could permit execution of arbitrary code if the server enabled Apache Solr's Config API.

Apache Solar version 7.0.1 suffers from XML external entity injection and remote code execution vulnerabilities.
