Nobody has the root password anymore, but fortunately, it's vulnerable to at least seven remote root sunrpc exploits. We "log in" by running a Python script that pops a root shell.
No, I am not kidding.
Edit: Checked out records: purchased and brought online in 1993.
Edit 2: In response to "why don't you just change the password?". When I asked, I was told they "can't" because they'd "lose access to the database". I didn't ask them to elaborate, because it would have opened a whole new can of horror worms, but I removed it from the Internet (it's on a non-routable, weakly "air gapped" network now).
