Description Sam Fowler 2018-07-05 22:37:48 EDT 
Apache Solr versions before 6.6.4 and 7.3.1 are vulnerable to XML external entity expansion (XXE) in Solr config files. A remote attacker could exploit this by uploading configsets using Solr's API allowing for arbitrary read of files on the Solr server or internal network.
