Following my last post I think I've managed to fix the flash file... The problem was with the decompiled source. I managed to find the original Actionscript source code for YUI 2.9.0 here:

https://github.com/yui/yui2/tree/master/src/uploader/as

I used that to replace some of the decompiled source from uploader.swf and then recompiled with a REGEX to sanitise allowedDomain. The result is a working uploader.swf that passes the exploit proof of concept.

Code:

uploader.swf?allowedDomain=\%22}%29%29%29}catch%28e%29{alert%28document.domain%29;}//

If there are any proper Flash developers out there who can double check my code I will be happy to share the source!
