CVE-2024-37900: XWiki Platform vulnerable to Cross-site Scripting through attachment filename in uploader
First published: Wed Jul 31 2024(Updated: )
### Impact When uploading an attachment with a malicious filename, malicious JavaScript code could be executed. This requires a social engineering attack to get the victim into uploading a file with a malicious name. The malicious code is solely executed during the upload and affects only the user uploading the attachment. While this allows performing actions in the name of that user, it seems unlikely that a user wouldn't notice the malicious filename while uploading the attachment. In order to reproduce, as any user, create a file named `"><img src=1 onerror=alert(1)>.jpg`. Then go to any page where you have edit rights and upload the file in the attachments tab. If alerts appear and display "1", then the instance is vulnerable. ### Patches This has been patched in XWiki 14.10.21, 15.5.5, 15.10.6 and 16.0.0. ### Workarounds We're not aware of any workaround except upgrading. ### References * https://jira.xwiki.org/browse/XWIKI-19611 * https://jira.xwiki.org/browse/XWIKI-21769 * https://jira.xwiki.org/browse/XWIKI-19602 * https://github.com/xwiki/xwiki-platform/commit/910a5018a50039e8b24556573dfe342f143ef949 ### Attribution This vulnerability has been independently reported by Aleksey Solovev (Positive Technologies) and Georgios Roumeliotis for TwelveSec.
