CVE-2022-41927
Cross-Site Request Forgery (CSRF) allowing to delete or rename tags
Description
### Impact It's possible with a simple request to perform deletion or renaming of tags without needing any confirmation, by using a CSRF attack. ### Patches The problem has been patched in XWiki 13.10.7, 14.4.1 and 14.5RC1. ### Workarounds It's possible to patch existing instances directly by editing the page Main.Tags and add this kind of check, in the code for renaming and for deleting: ``` #if (!$services.csrf.isTokenValid($request.get('form_token'))) #set ($discard = $response.sendError(401, "Wrong CSRF token")) #end ``` See the commit with the fix for more information about patching the page: https://github.com/xwiki/xwiki-platform/commit/7fd4cda0590180c4d34f557597e9e10e263def9e ### References * https://jira.xwiki.org/browse/XWIKI-19748 * https://github.com/xwiki/xwiki-platform/commit/7fd4cda0590180c4d34f557597e9e10e263def9e ### For more information If you have any questions or comments about this advisory: * Open an issue in [JIRA](https://jira.xwiki.org) * Email us at [security ML](mailto:security@xwiki.org)
