Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 10 Dec 2021. US federal agencies had to remediate by 10 Jun 2022, a deadline that has passed.

Required action. Apply updates per vendor instructions.

Description

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.
