Donnie, I believe this is the same attack I have been helping another customer with and it does not appear to be related to CF. Instead, it appears to start with a malware install of some kind on the server (and possibly a root kit) and then progress to the creation of accounts and the changing of file permissions. Another theory gaining weight (and illustrating that we don't know much yet) is that this attack is an agent on a client computer that piggybacks onto FTP - which explains a few things but not everything. I'm guessing some combination at this point.
Anyway, I agree that cfexecute is a dangerous tag that needs to be controlled, but it does not appear to be the cuprit. All of this advice is good, but the only place that CF comes into play on this particular hack happens to be the propensity to use "index.cfm" as the home page script. The attack targets "index.*" files and affects (on the server I am working with) Index.cfm, index.html and index.php etc. -Mark Mark A.

I would even bet that you are on a shared server (at HMS) since one of my client sites had this exact same problem. The attacker would have gained access to the file system (possibly via FTP) and executed code that injected the code into all index.* files on the server (not just your hosting account). We have had a lot of problems trying to get this sorted out. It appears that the issue was with security related to the windows script host and/or CFEXECUTE. The only thing you can do to prevent this is work with your hosting provider to secure the system or move to a VPS or dedicated account and make sure your FTP accounts are secure.
