How it was found

Hi,

I found a flash based XSS located here : https://polldaddy.com/swf/storage.swf?onload=alert(1)

It happends in the ExternalInterface.Call Function, when a parameter is inserted unfiltered it will allow XSS, you can patch it by only allowing : A-Z a-z 0-9

Best regards,

Olivier Beg
