--- -- By making heavy use of the <code>smb</code> library, this library will call various MSRPC -- functions. The functions used here can be accessed over TCP ports 445 and 139, -- with an established session. A NULL session (the default) will work for some -- functions and operating systems (or configurations), but not for others. -- -- To make use of these function calls, a SMB session with the server has to be -- established. This can be done manually with the <code>smb</code> library, or the function -- <code>start_smb</code> can be called. A session has to be created, then the IPC$ -- tree opened. -- -- Next, the interface has to be bound. The <code>bind()</code> function will take care of that. -- -- After that, you're free to call any function that's part of that interface. In -- other words, if you bind to the SAMR interface, you can only call the <code>samr_</code> -- functions, for <code>lsa_</code> functions, bind to the LSA interface, etc. Although functions -- can technically be called in any order, many functions depend on the -- value returned by other functions. I indicate those in the function comments, -- so keep an eye out. SAMR functions, for example, require a call to -- <code>connect4</code>. -- -- Something to note is that these functions, for the most part, return a whole ton -- of stuff in a table; basically, everything that is returned by the function. -- Generally, if you want to know exactly what you have access to, either display the -- returned data with a <code>print_table</code>-type function, or check the documentation (Samba 4.0's -- <code>.idl</code> files (in <code>samba_4.0/source/librpc/idl</code>; see below for link) are what I based -- the names on). -- -- The parameters for each function are converted to a string of bytes in a process -- called "marshalling". Functions here take arguments that match what a user would -- logically want to send. These are marshalled by using functions in the -- <code>msrpctypes</code> module. Those functions require a table of values that -- isn't very use friendly; as such, it's generated, when possible, in the functions -- in this module. The value returned, on the other hand, is returned directly to the -- user; I don't want to limit what data they can use, and it's difficult to rely on -- servers to format it consistently (sometimes a <code>null</code> is returned, and -- other times an empty array or blank string), so I put the onus on the scripts to -- deal with the returned values. -- -- When implementing this, I used Wireshark's output significantly, as well as Samba's -- <code>.idl</code> files for reference: -- http://websvn.samba.org/cgi-bin/viewcvs.cgi/branches/SAMBA_4_0/source/librpc/idl/. -- I'm not a lawyer, but I don't expect that this is a breach of Samba's copyright -- -- if it is, please talk to me and I'll make arrangements to re-license this or to -- remove references to Samba. -- -- Revised 07/25/2012 - added Printer Spooler Service (spoolss) RPC functions and -- constants [Aleksandar Nikolic] --@author Ron Bowes <ron@skullsecurity.net> --@copyright Same as Nmap--See http://nmap.org/book/man-legal.html ----------------------------------------------------------------------- local bin = require "bin" local bit = require "bit" local math = require "math" local msrpctypes = require "msrpctypes" local netbios = require "netbios" local os = require "os" local smb = require "smb" local stdnse = require "stdnse" local string = require "string" local table = require "table" _ENV = stdnse.module("msrpc", stdnse.seeall) -- The path, UUID, and version for SAMR SAMR_PATH = "\\samr" SAMR_UUID = string.char(0x78, 0x57, 0x34, 0x12, 0x34, 0x12, 0xcd, 0xab, 0xef, 0x00, 0x01, 0x23, 0x45, 0x67, 0x89, 0xac) SAMR_VERSION = 0x01 -- The path, UUID, and version for SRVSVC SRVSVC_PATH = "\\srvsvc" SRVSVC_UUID = string.char(0xc8, 0x4f, 0x32, 0x4b, 0x70, 0x16, 0xd3, 0x01, 0x12, 0x78, 0x5a, 0x47, 0xbf, 0x6e, 0xe1, 0x88) SRVSVC_VERSION = 0x03 -- The path, UUID, and version for SPOOLSS SPOOLSS_PATH = "\\spoolss" SPOOLSS_UUID = string.char(0x78, 0x56, 0x34, 0x12, 0x34, 0x12, 0xcd, 0xab, 0xef, 0x00, 0x01, 0x23, 0x45, 0x67, 0x89, 0xab) SPOOLSS_VERSION = 0x01 -- The path, UUID, and version for LSA LSA_PATH = "\\lsarpc" LSA_UUID = string.char(0x78, 0x57, 0x34, 0x12, 0x34, 0x12, 0xcd, 0xab, 0xef, 0x00, 0x01, 0x23, 0x45, 0x67, 0x89, 0xab) LSA_VERSION = 0 -- The path, UUID, and version for WINREG WINREG_PATH = "\\winreg" WINREG_UUID = string.char(0x01, 0xd0, 0x8c, 0x33, 0x44, 0x22, 0xf1, 0x31, 0xaa, 0xaa, 0x90, 0x00, 0x38, 0x00, 0x10, 0x03) WINREG_VERSION = 1 -- The path, UUID, and version for SVCCTL SVCCTL_PATH = "\\svcctl" SVCCTL_UUID = string.char(0x81, 0xbb, 0x7a, 0x36, 0x44, 0x98, 0xf1, 0x35, 0xad, 0x32, 0x98, 0xf0, 0x38, 0x00, 0x10, 0x03) SVCCTL_VERSION = 2 -- The path, UUID, and version for ATSVC ATSVC_PATH = "\\atsvc" ATSVC_UUID = string.char(0x82, 0x06, 0xf7, 0x1f, 0x51, 0x0a, 0xe8, 0x30, 0x07, 0x6d, 0x74, 0x0b, 0xe8, 0xce, 0xe9, 0x8b) ATSVC_VERSION = 1 -- UUID and version for epmapper e1af8308-5d1f-11c9-91a4-08002b14a0fa v3.0 EPMAPPER_PATH = "\\epmapper" EPMAPPER_UUID = string.char(0x08, 0x83, 0xaf, 0xe1, 0x1f, 0x5d, 0xc9, 0x11, 0x91, 0xa4, 0x08, 0x00, 0x2b, 0x14, 0xa0, 0xfa) EPMAPPER_VERSION = 3 -- This is the only transfer syntax I've seen in the wild, not that I've looked hard.
