Apache Solr DataImportHandler dataConfig Parameter Security Vulnerability

CVE-2019-0193 · HIGH Severity

AV:N/AC:L/AU:S/C:C/I:C/A:C

In Apache Solr, 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.
