# Vulnerability: Wordpress plugin Buddypress <= 1.9.1 privilege escalation
# Date: 13/02/2014
# Author: Pietro Oliva
# Vendor Homepage: http://buddypress.org
# Software Link: http://downloads.wordpress.org/plugin/buddypress.1.9.1.zip
# Version: 1.9.1
# CVE : [CVE-2014-1889]
# Responsibly disclosed and patched in version 1.9.2

it's possible to perform a privilege escalation attack due to a lack
of permissions check in the group creation process. A malicious user
could exploit this vulnerability to take control of every group
(change name, description, avatar and settings).
To exploit this vulnerability you have to follow these steps:

1) Create a cookie named bp_new_group_id=<id_of_victim_group>
2) Visit the url http://example.com/groups/create/step/group-details/
3) Enjoy the power
