Description:
~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

EasyDA by NCCGroup uses /tmp in an insecure manner.
1) Domain Admin credentials can be obtained by a low-privileged user
2) A low-privileged user can escalate to the user which runs EasyDA

Many problems
e.g.
      cat "$HASHFILE" |cut -d ":" -f 1 >/tmp/user.txt

      cat "$HASHFILE" |cut -d ":" -f 3,4 >/tmp/pass.txt

      paste /tmp/user.txt /tmp/pass.txt >/tmp/userpass.txt

etc.
