MS11-030: Vulnerability in DNS Resolution Could Allow Remote Code Execution (2509553) (remote check)

Critical Nessus Plugin ID 53514


Arbitrary code can be executed on the remote host through the installed Windows DNS client.


A flaw in the way the installed Windows DNS client processes Link- local Multicast Name Resolution (LLMNR) queries can be exploited to execute arbitrary code in the context of the NetworkService account.

Note that Windows XP and 2003 do not support LLMNR and successful exploitation on those platforms requires local access and the ability to run a special application. On Windows Vista, 2008, 7, and 2008 R2, however, the issue can be exploited remotely.


Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
