Goobi viewer: Solr query injection via the legacy RSS servlet q and filterQuery parameters

Impact

Goobi viewer versions prior to 26.05 are vulnerable to Solr query injection via the legacy RSS servlet's q and filterQuery parameters, allowing unauthenticated attackers to access restricted records. The vulnerability is due to improper input validation. This issue has been patched in version 26.05.

Original source description

The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. Prior to version 26.05, the legacy RSS servlet (RssResolver, GET /rss/) accepts the q and filterQuery parameters and concatenates them into Solr queries without validation. The servlet predates the REST API layer and lacks the input validation present in GET /api/v1/records/rss. q forms the main query body (wrapped only in literal parentheses); filterQuery is passed directly as a Solr fq. An unauthenticated attacker can inject Solr boolean operators to break out of the wrapping and render the trailing access-condition filter-query suffix optional, so that access-restricted records are included in the generated RSS feed. The q and filterQuery parameters are the same underlying vulnerability in the same servlet; q (the main query body) has the broader scope. This issue has been patched in version 26.05.
