This person left behind a server whose hatches are pretty tightly battened down.  I’ve volunteered to help regain access to the server.  I was able to recover the victim’s ssh key and log in to the server, but unfortunately sudo access is password protected so that has me stuck.  I also have their SHA512-hashed password from a backup.  Is there anyone here who can help either point me to a recent (Debian 3.2.102-1 x86_64) Linux local privilege escalation exploit or a good password cracker that I can use to try to get root on this machine?

Is the disk itself encrypted?  If not take it out and put it in a USB
enclsure and try ti mount it on another Debian machine.  Might as well
try the simplest method first.  Also you could suck up a copy of the
disk with dd so you have a copy if you mess it up.
