Summary: XWiki Platform Attachment UI vulnerable to cross-site scripting in the move attachment form

Details: ### Impact It's possible to store JavaScript in an attachment name, which will be executed by anyone trying to move the corresponding attachment. For example, an attachment with name `><img src=1 onerror=alert(1)>.jpg` will execute the alert. ### Patches This issue has been patched in XWiki 14.4RC1. ### Workarounds It is possible to fix the vulnerability by copying [moveStep1.vm](https://raw.githubusercontent.com/xwiki/xwiki-platform/xwiki-platform-14.0-rc-1/xwiki-platform-core/xwiki-platform-attachment/xwiki-platform-attachment-api/src/main/resources/templates/attachment/moveStep1.vm) to `webapp/xwiki/templates/moveStep1.vm` and replace ``` #set($titleToDisplay = $services.localization.render('attachment.move.title', [$attachment.name, $escapetool.xml($doc.plainTitle), $doc.getURL()])) ``` by ``` #set($titleToDisplay = $services.localization.render('attachment.move.title', [ $escapetool.xml($attachment.name), $escapetool.xml($doc.plainTitle), $escapetool.xml($doc.getURL()) ])) ``` See the corresponding [patch](https://github.com/xwiki/xwiki-platform/commit/fbc4bfbae4f6ce8109addb281de86a03acdb9277). ### References - https://jira.xwiki.org/browse/XWIKI-19667 ### For more information If you have any questions or comments about this advisory: - Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) - Email us at [Security Mailing List](mailto:[email protected])
