OF-1021: Openfire 3.10.2 Arbitrary File Upload - https://packetstormsecurity.com/files/133561/Openfire-3.10.2-Arbitrary-File-Upload.html
Further investigation suggests that while it is possible to update user permissions via a single request, this is only possible if an admin is already logged in to the Openfire admin console. However, combined with a XSS exploit, this could be used to escalate permissions unnoticed.
Pretty sure that this is just a particular exploit possible using CSRF attacks, rather than a vulnerability in itself. I'll try to see what we can do about this.
In testing 4.1.beta a CSRF token is now provided, and tested for on /user-edit-form.jsp.
This ticket can be closed.
