Summary

This vulnerability allows attackers to exploit certain XML configuration files within Apache Solr versions ranging from 6.0.0 to 7.3.1. By leveraging XML External Entity (XXE) processing, attackers can manipulate config files such as currency.xml and enumsConfig.xml to read arbitrary local files from the Solr server or the internal network. This risk is amplified because the affected files can be uploaded as configsets using Solr's API, potentially exposing sensitive information to unauthorized users.

Affected Version(s)

Apache Solr 6.0.0 to 6.6.4

Apache Solr 7.0.0 to 7.3.1
