Description

This module exploits a vulnerability in Apache Solr Velocity template. Currently, this module only supports Solr basic authentication.

From the Tenable advisory:
An attacker could target a vulnerable Apache Solr instance by first identifying a list
of Solr core names. Once the core names have been identified, an attacker can send a specially crafted
HTTP POST request to the Config API to toggle the params resource loader value for the Velocity Response
Writer in the solrconfig.xml file to true. Enabling this parameter would allow an attacker to use the Velocity
template parameter in a specially crafted Solr request, leading to RCE.
