Yes .. /var/www/html/website/ actually exist.
Yes, i am able to upload shell into /tmp/ and /usr/tmp/ . But how to exploit
it ?? If i upload the shell in these directories and view the shell using
load_file(), then its just showing me the php code and not the output of php
I am not clear with the concept of using UDF in injections. Can you please
elaborate on this stuff as well.
