  <name>Putting it together</name>
  <author>Z. Cliffe Schreuders</author>
  <description>
    A target server is leaking pieces of a login through two separate misconfigured
    services: an over-shared network file share reveals part of the puzzle, and an
    unusual open port hands out the rest to anyone who connects. Piece together the
    recovered credentials, log in as a regular user, and collect a flag from their
    home directory. From there, a permissive sudo rule lets an ordinary command break
    out into a root shell - work out which allowed command can be abused to complete
    the takeover.
