Impact
Any user with edit right on any page can execute any code on the server by adding an object of type
XWiki.SearchSuggestSourceClass
to their user profile or any other page. This compromises the confidentiality, integrity and availability of the whole XWiki installation.To reproduce on an instance, as a user without script nor programming rights, add an object of type
XWiki.SearchSuggestSourceClass
to your profile page. On this object, set every possible property to}}}{{async}}{{groovy}}println("Hello from Groovy!"){{/groovy}}{{/async}}
(i.e., name, engine, service, query, limit and icon). Save and display the page, then append?sheet=XWiki.SearchSuggestSourceSheet
to the URL. If any property displays asHello from Groovy!}}}
, then the instance is vulnerable.Patches
