Microsoft Windows Authenticated User Code Execution
This module uses a valid administrator username and password (or password hash) to execute an arbitrary payload. This module is similar to the "psexec" utility provided by SysInternals. This module is now able to clean up after itself. The service created by this tool uses a randomly chosen name and description.

Exploit Module Options
| RHOST | The target address |
| RPORT | Set the SMB service port (default: 445) |
| SHARE | The share to connect to, can be an admin share (ADMIN$,C$,...) or a normal read/write folder share (default: ADMIN$) |
| SMBDomain | The Windows domain to use for authentication (default: WORKGROUP) |
| SMBPass | The password for the specified username (default: ) |
| SMBUser | The username to authenticate as (default: ) |
| CHOST | The local client address |
| CPORT | The local client port |
| ConnectTimeout | Maximum number of seconds to establish a TCP connection |
| ContextInformationFile | The information file that contains context information |
| DB_REPORT_AUTH | Report an auth_note upon a successful connection |
| DCERPC::ReadTimeout | The number of seconds to wait for DCERPC responses |
| DisablePayloadHandler | Disable the handler code for the selected payload |
| EXE::Custom | Use custom exe instead of automatically generating a payload exe |
| EXE::FallBack | Use the default template in case the specified one is missing |
| EXE::Inject | Set to preserve the original EXE function |
| EXE::OldMethod | Set to use the substitution EXE generation method. |
| EXE::Path | The directory in which to look for the executable template |
| EXE::Template | The executable template file name. |
| EnableContextEncoding | Use transient context when encoding payloads |
| MOF_UPLOAD_METHOD | Use WBEM instead of RPC, ADMIN$ share will be mandatory. ( Not compatible with Vista+ ) |
| NTLM::SendLM | Always send the LANMAN response (except when NTLMv2_session is specified) |
| NTLM::SendNTLM | Activate the 'Negotiate NTLM key' flag, indicating the use of NTLM responses |
| NTLM::SendSPN | Send an avp of type SPN in the ntlmv2 client Blob, this allow authentification on windows Seven/2008r2 when SPN is required |
| NTLM::UseLMKey | Activate the 'Negotiate Lan Manager Key' flag, using the LM key when the LM response is sent |
| NTLM::UseNTLM2_session | Activate the 'Negotiate NTLM2 key' flag, forcing the use of a NTLMv2_session |
| NTLM::UseNTLMv2 | Use NTLMv2 instead of NTLM2_session when 'Negotiate NTLM2' key is true |
| Proxies | Use a proxy chain |
| SMB::ChunkSize | The chunk size for SMB segments, bigger values will increase speed but break NT 4.0 and SMB signing |
| SMB::Native_LM | The Native LM to send during authentication |
| SMB::Native_OS | The Native OS to send during authentication |
| SMB::VerifySignature | Enforces client-side verification of server response signatures |
| SMBDirect | The target port is a raw SMB service (not NetBIOS) |
| SMBName | The NetBIOS hostname (required for port 139 connections) |
| SSL | Negotiate SSL for outgoing connections |
| SSLVersion | Specify the version of SSL that should be used (accepted: SSL2, SSL3, TLS1) |
| VERBOSE | Enable detailed status messages |
| WORKSPACE | Specify the workspace for this module |
| WfsDelay | Additional delay when waiting for a session |
| DCERPC::fake_bind_multi | Use multi-context bind calls |
| DCERPC::fake_bind_multi_append | Set the number of UUIDs to append the target |
| DCERPC::fake_bind_multi_prepend | Set the number of UUIDs to prepend before the target |
| DCERPC::max_frag_size | Set the DCERPC packet fragmentation size |
| DCERPC::smb_pipeio | Use a different delivery method for accessing named pipes (accepted: rw, trans) |
| SMB::obscure_trans_pipe_level | Obscure PIPE string in TransNamedPipe (level 0-3) |
| SMB::pad_data_level | Place extra padding between headers and data (level 0-3) |
| SMB::pad_file_level | Obscure path names used in open/create (level 0-3) |
| SMB::pipe_evasion | Enable segmented read/writes for SMB Pipes |
| SMB::pipe_read_max_size | Maximum buffer size for pipe reads |
| SMB::pipe_read_min_size | Minimum buffer size for pipe reads |
| SMB::pipe_write_max_size | Maximum buffer size for pipe writes |
| SMB::pipe_write_min_size | Minimum buffer size for pipe writes |
| TCP::max_send_size | Maxiumum tcp segment size. (0 = disable) |
| TCP::send_delay | Delays inserted before every send. (0 = disable) |
