'printenv' is a test CGI script that tends to come default with most
Apache installation. Usually located in the "/cgi-bin/" directory.


An XSS vulnerbility exist which will allow anyone to input specially 
crafted links and/or other malicious/obscene scripts.


Example exploitation:

error, Click here!</a>


Fix:

Since 'printenv' is just an example CGI script that has no real use and 
has its own problems. Just remove it.
