CVE-2017-3163 Information

Description

When using the Index Replication feature Apache Solr nodes can pull index files from a master/leader node using an HTTP API which accepts a file name. However Solr before 5.5.4 and 6.x before 6.4.1 did not validate the file name hence it was possible to craft a special request involving path traversal leaving any file readable to the Solr server process exposed. Solr servers protected and restricted by firewall rules and/or authentication would not be at risk since only trusted clients and users would gain direct HTTP access.
