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.","provenance":"source","from":"NVD"},"summary":{"text":"Apache Solr's DataImportHandler module, which pulls data from databases and other sources, accepts a full DIH configuration through a request's \"dataConfig\" parameter, used by the admin screen's debug mode. Because a DIH configuration can contain scripts, an attacker with network access and high-privilege credentials can inject code through this parameter, and the feature remains exposed in Solr 8.2.0
