It was found that the SolrResourceLoader class in Apache Solr allowed loading of resources via absolute paths, or relative paths which were not sanitized for directory traversal. Some Solr components expose REST interfaces which load resources (XSL stylesheets and Velocity templates) via SolrResourceLoader, using paths identified by REST parameters. A remote attacker could use this flaw to load arbitrary local files on the server via SolrResourceLoader, potentially resulting in information disclosure or remote code execution.
