info:
  name: Apache Solr DataImportHandler <8.2.0 - Remote Code Execution
  author: pdteam
  severity: high
  description: |
    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.
  impact: |
    Successful exploitation of this vulnerability could lead to remote code execution, allowing an attacker to execute arbitrary commands on the affected system.
  remediation: |
    Starting with version 8.2.0 of Solr, use of this parameter requires setting the Java System property "enable.dih.dataConfigParam" to true.
