Wake Up Call
It was only a matter of time before the patch was reverse engineered and an exploit found for the vulnerability.
Thankfully the industry had a little more lead time on this one in terms of patching systems before the PoC emerged. Well, at least compared to Heartbleed and Shellshock.
No doubt however we'll still be finding this vulnerability in penetration test for years to come. I mean I still regularly find ms08-067 at some client sites.
