CVE-2024-37901

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with edit right on any page can perform arbitrary remote code execution by adding instances of `XWiki.SearchSuggestConfig` and `XWiki.SearchSuggestSourceClass` to their user profile or any other page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been patched in XWiki 14.10.21, 15.5.5 and 15.10.2.

Any user with edit right on any page can perform arbitrary remote code execution by adding instances of `XWiki.SearchSuggestConfig` and `XWiki.SearchSuggestSourceClass` to their user profile or any other page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been patched in XWiki 14.10.21, 15.5.5 and 15.10.2.

### Impact Any user with edit right on any page can perform arbitrary remote code execution by adding instances of `XWiki.SearchSuggestConfig` and `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.SearchSuggestConfig` to your profile page, and an object of type `XWiki.SearchSuggestSourceClass` as well. On this last object, set both `name` and `icon` properties to `$services.logging.getLogger("attacker").error("I got programming: $services.security.authorization.hasAccess('programming')")` and `limit` and `engine` to `{{/html}}{{async}}{{velocity}}$services.logging.getLogger("attacker").error("I got programming: $services.security.authorization.hasAccess('programming')"){{/velocity}}{{/async}}`. Save and display the page. If the logs contain any message `ERROR attacker - I got programming: true` then the instance is vulnerable. ### Patches This vulnerability has been patched in XWiki 14.10.21, 15.5.5 and 15.10.2. ### Workarounds We're not aware of any workaround except upgrading. ### References - https://jira.xwiki.org/browse/XWIKI-21473 - https://github.com/xwiki/xwiki-platform/commit/742cd4591642be4cdcaf68325f17540e0934e64e

XWiki Platform es una plataforma wiki genérica que ofrece servicios de ejecución para aplicaciones creadas sobre ella. Cualquier usuario con derecho de edición en cualquier página puede realizar la ejecución remota de código arbitrario agregando instancias de `XWiki.SearchSuggestConfig` y `XWiki.SearchSuggestSourceClass` a su perfil de usuario o a cualquier otra página. Esto compromete la confidencialidad, integridad y disponibilidad de toda la instalación de XWiki. Esta vulnerabilidad ha sido parcheada en XWiki 14.10.21, 15.5.5 y 15.10.2.
