XWiki Platform: Remote code execution through space title and Solr space facet

Published: 4/10/2024Modified: 4/10/2024

Description

### Impact By creating a document with a specially crafted title, it is possible to trigger remote code execution in the (Solr-based) search in XWiki. This allows any user who can edit the title of a space (all users by default) to execute any Groovy code in the XWiki installation which compromises the confidentiality, integrity and availability of the whole XWiki installation. To reproduce, as a user without script nor programming rights, create a document with title `{{/html}}{{async}}{{groovy}}println("Hello from Groovy Title!"){{/groovy}}{{/async}}` and content `Test Document`. Using the search UI, search for `"Test Document"`, then deploy the `Location` facet on the right of the screen, next to the search results. The installation is vulnerable if you see an item such as: ``` Hello from Groovy Title! </a> <div class="itemCount">1</div> </li> </ul> {{/html}} ``` ### Patches This has been patched in XWiki 14.10.20, 15.5.4 and 15.10 RC1. ### Workarounds Modify the `Main.SolrSpaceFacet` page following this [patch](https://github.com/xwiki/xwiki-platform/commit/acba74c149a041345b24dcca52c586f872ba97fb#diff-22dd1949ed9019a39f2550f5a953a1a967c30a374dc9eeddb74069bf229b17d5). ### References * https://jira.xwiki.org/browse/XWIKI-21471 * https://github.com/xwiki/xwiki-platform/commit/acba74c149a041345b24dcca52c586f872ba97fb * https://github.com/xwiki/xwiki-platform/commit/74e301c481e69eeea674dac7fed6af3614cf08c5
