Apache Solr Remote Code Execution via Velocity Template
Description
This module exploits a vulnerability in Apache Solr <= 8.3.0 which allows remote code execution via a custom 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.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
