### 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 * h...

### Impact When a user has edit but not view right on a page in XWiki, that user can delete the page and replace it by a page with new content without having delete right. The previous version of the page is moved into the recycle bin and can be restored from there by an admin. As the user is recorded as deleter, the user would in theory also be able to view the deleted content, but this is not directly possible as rights of the previous version are transferred to the new page and thus the user still doesn't have view right on the page. From all we examined, it therefore doesn't seem to be possible to exploit this to gain any rights. To reproduce, just replace `view` by `edit` in the URL of a page that you cannot view but edit and save. This should send the page to the recycle bin and replace it by an empty one if the XWiki installation is vulnerable. After the fix, an error is displayed when saving. ### Patches This has been patched in XWiki 14.10.21, 15.5.5 and 15.10.6 by cancelli...

This Metasploit module exploits an authenticated administrator-level vulnerability in Atlassian Confluence, tracked as CVE-2024-21683. The vulnerability exists due to the Rhino script engine parser evaluating tainted data from uploaded text files. This facilitates arbitrary code execution. This exploit will authenticate, validate user privileges, extract the underlying host OS information, then trigger remote code execution. All versions of Confluence prior to 7.17 are affected, as are many versions up to 8.9.0.
