MS05-051 POC Exploit
A proof of concept (PoC) exploit was released against systems vulnerable
to MS05-051. MS05-051 was released in October. The vulnerability does allow for
arbitrary code execution in systems with the Microsoft Distriuted Transaction Coordinator (MSDTC) enabled.

In order to disable MSDTC, enter the following command:
sc stop MSDTC & sc config MSDTC start= disabled

By default, port 3372 is used by the exploit. The packet send will cause a denial of service condition. At this point, we see only little activity at port 3372, likely due to the fact that this PoC exploit does not actually execute any "useful" code.
