Cross site scripting in registration template in xwiki-platform
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
We found a possible XSS vector in the `registerinline.vm` template related to the `xredirect` hidden field. This template is only used in the following conditions: - the wiki must be open to registration for anyone - the wiki must be closed to view for Guest users (more specifically the XWiki.Registration page must be forbidden in View for guest user)
Potential impact
We found a possible XSS vector in the registerinline.vm template related to the xredirect hidden field. This template is only used in the following conditions: - the wiki must be open to registration for anyone - the wiki must be closed to view for Guest users (more specifically the XWiki.Registration page must be forbidden in View for guest user) A way to obtain the second condition is when administrators checked the "Prevent unregistered users from viewing pages, regardless of the page rights" box in the administration rights.
