what is there to upload? all it takes is a var that is not properly sanitized 
that references a shell script on another site which then executes in the 
context of the server with the bad code... this is all too common an occurrence 
as my IDS shows on my practically invisible site... this isn't sql injection or 
anything like that but simply stuffing a POST or GET var with something like 
"hxxp://bad.domain.tld/shell_script" and having the code actually get it and 
execute it...

proper sanitizing of ALL vars, whether user input or "hidden" must be done in 
any web application to ensure that what is being received is valid for the 
application...
