Product:

==============================
sqlbuddy suffers from directory traversal whereby a user can move about directories an read any PHP and non PHP files by appending
the '#' hash character when requesting files via URLs.

After adding the '#' character as a delimiter any non PHP will be returned and rendered by subverting the .php concatenation used
by sqlbuddy when requesting PHP pages via POST method.
