.vuln/

There isn't any kind of file extentions check in: "uu_file_upload.js" and "uber_uploader_file.js".

.extentions/

you can submit files with extensions like: .html, .txt, .asp, etc...

you can upload all extensions, except: sh, php, php3,php4, php5, py, shtml, phtml, cgi, pl, plx, htaccess, htpasswd.

.PoC/

http://www.localhost/uu_file_upload.php

http://www.localhost/uber_uploader_file.php

.deface/

Once the file is uploaded you can see it in /uploads/

http://www.localhost/uploads/[YourFile]

.fixed/

To fix it, you have to modify "Check for illegal file extentions" and "Check for legal file extentions" in the file "uu_file_upload.js" or "uber_uploader_file.js".

It doesn't go on if its diferent to the allowed extensions.

[code]

// Check for illegal file extentions

function checkAllowFileExtensions(){

if(!check_allow_extensions){ return true; }

else{

alert('Sorry, uploading a file with the extension "' + file_extension + '" is not allowed.');

return true;

}

}

// Check for legal file extentions

function checkAllowFileExtensions(){

if(!check_allow_extensions){ return false; }

else{

alert('Sorry, uploading a file with the extension "' + file_extension + '" is not allowed.');

return true;

}

}

[/code]
