XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the deletespace template to perform a XSS, e.g. by using URL such as: > xwiki/bin/deletespace/Sandbox/?xredirect=javascript:alert(document.domain). This vulnerability exists since XWiki 3.4-milestone-1. The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1.

Multiple cross-site scripting (XSS) vulnerabilities in XWiki Enterprise 3.4 allow remote attackers to inject arbitrary web script or HTML via the (1) XWiki.XWikiComments_comment parameter to xwiki/bin/commentadd/Main/WebHome, (2) XWiki.XWikiUsers_0_company parameter when editing a user profile, or (3) projectVersion parameter to xwiki/bin/view/DownloadCode/DownloadFeedback.
