This module exploits a stack overflow in eDirectory 8.8 iMonitor
service. This vulnerability was discovered by CIRT.DK and released
through the ZDI program. This module was based on the edirectory_imonitor
exploit supplied by an anonymous user. If you feel like evading an IDS,
just set 'RPORT' to 8030 and 'SSL' to 1 :-)
