Apache Solr is vulnerable to remote code execution vulnerabilities via the DataImportHandler, an optional but popular module to pull in data from databases and other sources. The module 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.
