Short explanation
An input validation flaw in the Goobi viewer web application allows sanitization logic to be bypassed using double braces, leading to arbitrary Solr local-param injection.
This vulnerability in the shared sanitizer allows any endpoint routing user input through the function to be impacted, potentially introducing information disclosure risks.
What should be done?
- Follow the vendor advisory for update instructions
- Review and verify input sanitization controls
Chain of evidence and sources
Goobi viewer uygulamasında sürüm 23.03 ile 26.05 arasında cleanUpQuery fonksiyonu etkilenmektedir.
SolrTools.cleanUpQuery fonksiyonundaki regex süzgeci, çift süslü parantez sarmalama yöntemiyle atlatılabilmektedir.
Show the technical text from the sources
The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. From version 23.03 to before version 26.05, SolrTools.cleanUpQuery() strips Solr local-parameter syntax ({!...}) from user-supplied query strings before they reach Solr. Its regex can be bypassed by wrapping the local parameter in a second pair of curly braces ({{!...}}): the outer braces are stripped, the inner {!...} survives intact, and a valid Solr local parameter is forwarded. The flaw is in the shared sanitizer, so it affects any endpoint that routes user input through cleanUpQuery. The double-brace bypass applies from v23.10 (the greedy \{(.+)\} regex); a related bare-!join rewrap path is present. This issue has been patched in version 26.05.
