The DataImportHandler, an optional but popular module to pull in data from databases and other sources, has a feature in which the whole DIH configuration can come from a request's "dataConfig" parameter. The debug mode of the DIH admin screen uses this to allow convenient debugging / development of a DIH config. Since a DIH config can contain scripts, this parameter is a security risk. Starting with version 8.2.0 of Solr, use of this parameter requires setting the Java System property "enable.dih.dataConfigParam" to true.

Affects: fedora-all [bug 1736775]
This vulnerability is out of security support scope for the following products:
* Red Hat JBoss Fuse Service Works 6
* Red Hat Enterprise Application Platform 6
Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.
Edit solrconfig.xml to configure all DataImportHandler usages with an "invariants" section listing the "dataConfig" parameter set to am empty string, or ensure your network settings are configured so that only trusted traffic communicates with Solr, especially to the DataImportHandler (although this is a best practice regardless) (ref: https://issues.apache.org/jira/browse/SOLR-13669)
This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):
Marking JDV-6 and EAP-6 as not affected because the affected class is the part of solr-dataimporthandler.jar artifact which is not shipped with EAP-6 and JDV-6 distributions.
