XWiki Platform allows remote code execution as guest via SolrSearchMacros request
CISA confirms exploitation of this vulnerability in real attacks. Prioritise checking whether your application is affected. CISA KEV · CC0 1.0
Impact
Any guest can perform arbitrary remote code execution through a request to SolrSearch. This impacts the confidentiality, integrity and availability of the whole XWiki installation.
To reproduce on an instance, without being logged in, go to <host>/xwiki/bin/get/Main/SolrSearch?media=rss&text=%7D%7D%7D%7B%7Basync%20async%3Dfalse%7D%7D%7B%7Bgroovy%7D%7Dprintln%28"Hello%20from"%20%2B%20"%20search%20text%3A"%20%2B%20%2823%20%2B%2019%29%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D%20. If there is an output, and the title of the RSS feed contains Hello from search text:42, then the instance is vulnerable.
Patches
This vulnerability has been patched in XWiki 15.10.11, 16.4.1 and 16.5.0RC1.
Workarounds
This line in Main.SolrSearchMacros can be edited to match the rawResponse macro defined here with a content type of application/xml, instead of simply outputting the content of the feed.
