(lighttpd: Script source disclosure)

    lighttpd uses file extensions to determine which elements are programs
    that should be executed and which are static pages that should be sent
    as-is. By appending %00 to the filename, you can evade the extension
    detection mechanism while still accessing the file.
  
Impact :

    A remote attacker could send specific queries and access the source of
    scripts that should have been executed as CGI or FastCGI applications.
  
Workaround :

    There is no known workaround at this time."
