[I agree with Matthew & Brian. If cmd.exe can be run from a 
[browser using file:// irrespective of cross-zone security 
[boundaries then there are *much* other urgent things to be attended.
[
[However, there are other attack vectors out of which few are 
[already mentioned by Nick. This can definitely be exploitable 
[in conjunction with other attack vectors.
