Apache Solr DataImportHandler Code Injection Vulnerability

KEVHIGH 7.2EPSS 83.5%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 10 June 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

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.
