I haven't had the chance to test it in a controlled environment yet.
It seems to work.
It appears Cisco has seen the posting too. The Cisco PSIRT updated their announcement to 1.4 at 5am this morning. The sentence in the "Exploitation and Public Announcments" section is new and states that they are aware that the exploitation "has been publised on a public mailing list".
The link is the same, but the version number has changed:
