# Exploit Title: jQuery uploadify v2.1.0 Remote File Upload
# Date: 21/01/2010
# Author: k4cp3r/Ablus
# Version: v2.1.0



(uploadify.swf) Actionscript:

function setAllowedTypes():void {
allowedTypes = [];
if (param.fileDesc && param.fileExt) {
var fileDescs:Array = param.fileDesc.split('|');
var fileExts:Array = param.fileExt.split('|');
for (var n = 0; n < fileDescs.length; n++) {
allowedTypes.push(new FileFilter(fileDescs[n], fileExts[n]));
}
}
}
setAllowedTypes();

The FileFilter class is used to indicate what files on the user's system are shown in the file-browsing dialog box that is displayed when the FileReference.browse() method; a user can simply bypass this filter by writing the malicious file name and path on the file browser dialog box rather than navigating and choosing it.

Exploit:

#1 : upload your file ie (shell.php)
#2 : Retreive the 'folder' parameter passed to uploadify jquery function
from the head of the page source code ie('folder': 'files/',)
#3 : Navigate to your file ie(http://site/files/shell.php)

Fix:

A quick fix is to validate your file type inside uploadify.php before saving it
OR to randomize your file names :)
