Apache Solr is a search platform used by many enterprise companies to add a full text search functionality to their websites. Often hidden behind firewalls, it provides a rich API to search across large datasets. If this API is used by web applications in a wrong way, it may open a possibility for injection attacks to completely modify the query logic. In this talk we’ll shed some light on the new type of vulnerabilities for web applications - Solr parameter injection, and provide some useful ways how to achieve remote code execution through it. We also provide exploits for almost all known vulnerabilities for Apache Solr, including the two new RCEs we reported this year.
