Overview
Characteristics

The management interface allow any registred user to delete his own private messages. By forging the message number to delete he can actually delete all messages on the backend database. The messages subject are stored on a different table and they will remain untouched but all messages body will be removed.
A proof of concept demonstrating how to delete all private messages on a victim server has been released to the public.
