Script for CVE-2020-1350/KB4569509 Workaround

Recommended Posts

(Please not that this is the WORKAROUND not the actual patch)  KB4569509: Guidance for DNS Server Vulnerability CVE-2020-1350 - seems to be the talk of the net this afternoon.  I wrote a quick script to check for the registry key and set it if the key is not present or set it if the key has the default value. (Microsoft's article does not clarify the type of value to create....had to verify it via another post)

 For those that prefer batch'n it:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters" /v "TcpReceivePacketSize" /t REG_DWORD /d 0xFF00 /f

net stop DNS && net start DNS
