“The Windows DNS client doesn't do enough sanity checking when it processes a DNS response that contains an NSEC3 record.
Malformed NSEC3 records can trigger this vulnerability and corrupt the memory of the DNS client.
This can help an attacker bypass some of the protections Microsoft has built into Windows to protect against memory corruption vulnerabilities,” said Freeman.
My script script will not work on any DNS server, you need to run Windows 2008 or later DNS, running against Windows 2003 DNS servers will yield strange/wrong results.

“If an attacker has a foothold in your corporate network, they may exploit this issue to gain access to additional systems, possibly stealing sensitive information about customers or operations,” the FAQ stated.
