If your recursive function is relatively simple, you can probably write it as a CF 5-compliant user-defined function, using CFSCRIPT. CFSCRIPT is a tag in which you can write CF commands using a JavaScript-like language, which uses the same syntax and control flow structures as JavaScript, but uses CFML operators and expressions. You can't use CFML tags within a CFSCRIPT tag, though, and CFSCRIPT doesn't support all the things you can do with CFML tags, such as querying a database. Keep in mind that the host would have to be using CF 5 or higher for this to work. Alternatively, you could write a recursive custom tag. However, this is the least desirable alternative, as custom tags don't provide any built-in ability to return values (you can write that ability into your code, though) and they tend to negatively affect performance. Nevertheless, if you need recursion and you're using a version of CF prior to 5, that's the only way you can do it within CFML.
