I don't know how to do it work with Net::SSH2 but with Net::OpenSSH and Expect it is pretty easy: 
use Net::OpenSSH;
use Expect;

my $ssh = Net::OpenSSH->new($host, password => $password);

my ($pty, $pid) = $ssh->open2pty("sudo cat /etc/shadow")
    or die "open2pty failed: " . $ssh->error . "\n";

my $expect = Expect->init($pty);
$expect->raw_pty(1);
# $expect->log_user(1);

$expect->expect($timeout, ':')
    or die "expect failed\n";
$expect->send("$password\n");
$expect->expect($timeout, "\n")
    or die "bad password\n";

while(<$pty>) {
    print "$. $_"
}
