fixation: it is real, and very easy!


and now i send you this link you click it and your session is run under
the id 1234 - now i wait till you logged in and i can use this session
id to call the page by myself and be logged in with your details

but of course this is not possible with PMA currently - as the auth is
not handled with session!

hijacking same as above, just you don't send the url but catch it
somewhere, f.e. at the router or proxy - did you never tried to copy the
url from one brwoser to another? with cookie based session ids this will
not work you found yourself always on the login screen, with url based
session id it works!
