CVE-2024-31982

XWiki Platform is a generic wiki platform. Starting in version 2.4-milestone-1 and prior to versions 4.10.20, 15.5.4, and 15.10-rc-1, XWiki's database search allows remote code execution through the search text. This allows remote code execution for any visitor of a public wiki or user of a closed wiki as the database search is by default accessible for all users. This impacts the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been patched in XWiki 14.10.20, 15.5.4 and 15.10RC1. As a workaround, one may manually apply the patch to the page `Main.DatabaseSearch`. Alternatively, unless database search is explicitly used by users, this page can be deleted as this is not the default search interface of XWiki.

### Impact XWiki's database search allows remote code execution through the search text. This allows remote code execution for any visitor of a public wiki or user of a closed wiki as the database search is by default accessible for all users. This impacts the confidentiality, integrity and availability of the whole XWiki installation. To reproduce on an instance, without being logged in, go to `<hostname>/xwiki/bin/get/Main/DatabaseSearch?outputSyntax=plain&text=%7D%7D%7D%7B%7Basync%20async%3Dfalse%7D%7D%7B%7Bgroovy%7D%7Dprintln%28%22Hello%20from%22%20%2B%20%22%20search%20text%3A%22%20%2B%20%2823%20%2B%2019%29%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D%20`. If the title of the RSS channel contains `Hello from search text:42`, the instance is vulnerable. ### Patches This vulnerability has been patched in XWiki 14.10.20, 15.5.4 and 15.10RC1. ### Workarounds It is possible to manually apply [this patch](https://github.com/xwiki/xwiki-platform/commit/95bdd6cc6298acdf7f8f21298d40eeb8390a8565#diff-ef3314b8bb489e5368618ea1940c59098b18ec2246cc65fe337ae636de87e404) to the page `Main.DatabaseSearch`. Alternatively, unless database search is explicitly used by users, this page can be deleted as this is not the default search interface of XWiki. ### References * https://jira.xwiki.org/browse/XWIKI-21472 * https://github.com/xwiki/xwiki-platform/commit/95bdd6cc6298acdf7f8f21298d40eeb8390a8565

XWiki Platform es una plataforma wiki genérica. A partir de la versión 2.4-milestone-1 y anteriores a las versiones 4.10.20, 15.5.4 y 15.10-rc-1, la búsqueda en la base de datos de XWiki permite la ejecución remota de código a través del texto de búsqueda. Esto permite la ejecución remota de código para cualquier visitante de un wiki público o usuario de un wiki cerrado, ya que la búsqueda en la base de datos es accesible de forma predeterminada para todos los usuarios. Esto afecta la confidencialidad, integridad y disponibilidad de toda la instalación de XWiki. Esta vulnerabilidad ha sido parcheada en XWiki 14.10.20, 15.5.4 y 15.10RC1. Como workaround, se puede aplicar manualmente el parche a la página "Main.DatabaseSearch". Como workaround, a menos que los usuarios utilicen explícitamente la búsqueda en la base de datos, esta página se puede eliminar ya que no es la interfaz de búsqueda predeterminada de XWiki.
