"The version of Apache Solr running on the remote web server is
affected by a directory traversal vulnerability because the
'SolrResourceLoader' class fails to restrict access to the loading of
specially crafted XLS stylesheets and velocity templates. A remote,
unauthenticated attacker can exploit this issue by crafting a URL with
directory traversal characters to access resources outside of the
instance directory.");
