CVE-2023-35156

CVE-2023-35156: XWiki Platform vulnerable to reflected cross-site scripting via xredirect parameter in delete template

Impact

Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the delete template to perform a XSS, e.g. by using URL such as:

xwiki/bin/get/FlamingoThemes/Cerulean?xpage=xpart&vm=delete.vm&xredirect=javascript:alert(document.domain)

This vulnerability exists since XWiki 6.0-rc-1.

Patches

The vulnerability has been patched in XWiki 14.10.6 and 15.1. Note that a partial patch has been provided in 14.10.5 but wasn't enough to entirely fix the vulnerability.

Workarounds

It's possible to workaround the vulnerability by editing the template delete.vm to perform checks on it, but note that the appropriate fix involves new APIs that have been recently introduced in XWiki. See the referenced jira tickets.

Root Cause Analysis

The vulnerability stemmed from handling the 'xredirect' parameter in delete.vm template. The original code used #set($cancelUrl = "$request.xredirect") without validation, allowing XSS via javascript: URIs. The patch introduced #getSanitizedURLAttributeValue macro and $escapetool.xml escaping, confirming the lack of proper sanitization was the root cause. The file path and vulnerable pattern are explicitly shown in commit diffs and advisory descriptions.
