Hi all. Do u guy all here wanna HACK.
If yes,I guessing that currently what u need to know is the target server infomation,isn'it .

Here I provide u some solution to do it:

1. Search Google with
/horde/imp

2. Click on some result
ex: https://www.xxxx.com/horde/imp

3. Then add "test.php" string at the end of url like this:

https://www.xxxx.com/horde/imp/test.php

4. If this exploit not fix yet, it will show up
screen like this



5. So, Upto this Step I think all of u will found out what will need to do next. ;-) to collect the useful data of the target server.
