Title: CVE-2019-0193: Apache Solr, Remote Code Execution via DataImportHandler category: solr/security cve: CVE-2019-0193
Severity: High
Vendor:
The Apache Software Foundation
Versions Affected:
Description:
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.
Mitigation:
