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.
