JomSocial 1.8.8 Shell Upload

`There is a file upload vulnerability in version 1.8.8 and earlier of  
JomSocial, the popular community extension for Joomla!.  
  
Successful exploitation of this exploit requires the site to be  
configured to allow users to upload video files directly, which is  
disabled by default. If this feature is enabled, any file uploaded via  
the "add video" upload form will end up in  
http://[victim]/images/originalvideos/[your account's user id]/[unique  
file name]. This folder is not protected with an index, so if indexes  
are allowed retrieving the shell's filename is trivial.  
  
Listed on the JomSocial Changelog as "BUG: 4495"
