Note that I can't run Net::SSH since I don't have access to additional modules

Yes, even you can use CPAN - Net::OpenSSH is a pure-Perl module with no dependencies, which means it can be simply copied over.

use Net::OpenSSH;
my $ssh = Net::OpenSSH->new($host);
die "Couldn't establish SSH connection: ".$ssh->error if $ssh->error;
my ($in, $pid) = $ssh->pipe_in('bash','-s')
    or die "pipe_in failed: ".$ssh->error;
print $in <<'EOF';
# ...
EOF
close $in or die "close failed";
