This is not really a vulnerability.  It is more a
server setup problem.

Normally, you should not be able to browse files in
/cgi-bin directory; you should only be able to execute
scripts and display the page resulting from them. 
BUT, we do live in an imperfect world and some server
DO allow viewing of files in /cgi-bin directory and so
IT IS a problem, nonetheless.  To eliminate this
problem, please see

Thanks.
