CMailServer 3.30 uses sprintf() without any previous bounds checking while
testing for the presence of the passed USER argument's home directory within
'mail'..

sprintf(%s\\mail\\%s, CMail path ptr, USER arg ptr)

you know how the story goes, we can overwrite some serious EIP action..
see attached exploit.. a patch has also been included to prevent ownaging
