    SUMMARY

     <http://www.cgiscript.net/> csFAQ is "an automated system for displaying
    FAQs (frequently asked questions) written by CGI Scripts". A vulnerability
    in csFAQ allows remote attacker to reveal the path under which the product
    has been installed.

    to determine the full path to the web root directory and other potentially
    sensitive information.

    http://www.attack.com/cgi-script/csFAQ/csFAQ.cgi?command=viewFAQ&database=/.darkbicho the following error response is returned:
