For those of you who don’t keep up with ColdFusion security bulletins, one was issue recently that you might want to look into, especially if you expose web services.
ColdFusion MX and JRun 4.0 Web Services may be vulnerable to a Denial-of-Service attack from maliciously constructed SOAP requests. ColdFusion Version 5 and earlier versions and JRun 3.1 and earlier versions do not support Web Services and are not vulnerable.
If you’re behind in your security patches, while you’re at it, you might want to install this one, as well:
ColdFusion MX 6.1 is vulnerable to a denial of service attack if a malicious user creates a ficticious request containing a large number of form fields.
