I've just spent a couple of hours studying code to see if there is an easy, safe and simple way to do what you want.
You can't simply pass the user name and password in the query string – svManager doesn't work like that.
I definitely do not think you should hack the svManager security code – that's bound to get you (and me) in trouble somewhere down the line.
The only option I can think of is to spoof the svManager login form from within your cms. In principle that is easy. All you need to do in your cms is set two php variables:
$_POST['user'] = 'theusernamethatyousetinsvmanageradmin'
$_POST['password'] = 'the-PassWord_that!You$Set*In(svManager]Admin'
and then load one of the svManager pages.
Of course the form or whatever mechanism you use to set the post variables should only be accessible to valid logged-in cms users.
There is one major drawback with this approach – you need to store the user name and password somewhere on the server. And you need to store them in plain text – not encrypted. This is a BIG BIG security hole. It defeats the whole point of password encryption.
I wouldn't do it.
