Descriptions

This vulnerability in Apache Solr 6.0.0 to 6.6.4 and 7.0.0 to 7.3.1 relates to an XML external entity expansion (XXE) in Solr config files (currency.xml, enumsConfig.xml referred from schema.xml, TIKA parsecontext config file). In addition, Xinclude functionality provided in these config files is also affected in a similar way. The vulnerability can be used as XXE using file/ftp/http protocols in order to read arbitrary local files from the Solr server or the internal network. The manipulated files can be uploaded as configsets using Solr's API, allowing to exploit that vulnerability.

Esta vulnerabilidad en Apache Solr, de la versión 6.0.0 a la 6.6.4 y de la versión 7.0.0 a la 7.3.1, está relacionada con una expansión XEE (XML External Entity) en los archivos de configuración de Solr (currency.xml, enumsConfig.xml referido desde schema.xml y el archivo de configuración TIKA parsecontext). Además, la funcionalidad Xinclude en estos archivos de configuración también se ha visto afectada de forma similar. La vulnerabilidad puede emplearse como XEE mediante el uso de protocolos file/ftp/http para leer archivos locales arbitrarios del servicio Solr o de la red interna. Los archivos manipulados pueden ser subidos como configsets mediante la API de Solr, lo que permite explotar esta vulnerabilidad.
