Description

The extension passes the user-supplied search query parameter to Apache Solr without restricting advanced Solr query syntax such as wildcards, field selectors and range queries. A remote, unauthenticated attacker can use this syntax to enumerate indexed field names and extract their stored values through boolean- and range-based blind extraction techniques, independent of any site-specific configuration.
