Known Exploited Vulnerability

Apache Solr DataImportHandler Code Injection Vulnerability

Vendor / product: Apache / Solr

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.

Weakness classification

  • CWE-94: Improper Control of Generation of Code ('Code Injection')
