I'm clueless about the OS, but what I wonder is:

Is this LAST thing part of the /etc/issue variant? And - do you really think these guys (seems to be mostly two persons) logged in as coldfusion user?

I'd be very sceptical and - as someone else said it much earlier than me - treat this as a complete disaster.

That was my assumption as well. Surely if it were rooted there would be more interesting files included?

Though if I were the admin of senate.gov, I would treat it is a full compromise.
