James Lee 9c3664bd45 Unify reverse_http and reverse_https 
This will make copy-pasta less painful in the future.  There's still the
problem of reverse_https_proxy being very similar, but the logic in how
it gets generated in the module is more than i want to tackle right now

Raphael Mudge 788c96566f Allow HTTP stager to work with authenticated proxies 
The HttpOpenRequest function from WinINet requires the
INTERNET_FLAG_KEEP_CONNECTION flag to communicate through an
authenticated proxy.

From MSDN ( http://tinyurl.com/chwt86j ):

"Uses keep-alive semantics, if available, for the connection. This
 flag is required for Microsoft Network (MSN), NT LAN Manager (NTLM),
 and other types of authentication."

Without this flag, the HTTP stager will fail when faced with a proxy
that requires authentication. The Windows HTTPS stager does not have
this problem.

For HTTP Meterpreter to communicate through an authenticated proxy a
separate patch will need to be made to the Meterpreter source code.
This is at line 1125 of source/common/core.c in the Meterpreter source
code.

My motivation for this request is for windows/dllinject/reverse_http
to download a DLL even when faced with an authenticated proxy. These
changes accomplish this.

Test environment:

I staged a SmoothWall device with the Advanced Proxy Web Add-on. I
enabled Integrated Windows Authentication with a W2K3 DC. I verified
the HTTP stager authenticated to and communicated through the proxy
by watching the proxy access.log

Michael Schierl 46a5c4f4bf Improve RC4 shellcode 
ESI is not clobbered; no need to clear EDX as only DL is filled before and
it is overwritten before use.

Shellcodes in ruby modules not regenerated, but I guess you want to
regenerate them again anyway :-)

Michael Schierl cb06262002 Add shellcode for RC4 bind and reverse stagers 
Those stagers will encrypt the initial stage with a 128-bit RC4 key and
the stage length with a XOR key. Both keys are embedded in the stager.

This should provide good evasion capabilities in addition to some
protection against MITM reversing (if the stager is sent a different
route, like in an executable on an USB key).

Note that, from a cryptanalyst's standpoint, it is a bad idea to reuse the
same stager (or stagers with the same RC4 and XOR keys) more than once
since an identical key will result in an identical keystream and make
correlation attacks easy. But I doubt that matters in practice.

Also note that since communication after the initial statging is not
encrypted, these stagers should be used in combination with additional
encryption support in the payloads (like Meterpreter).

Michael Schierl b4fd341fb6 Add shellcode for RC4 decoding 
Provided as a block to be included into stagers and/or decoder stubs.
Also included is a test shellcode that can be used for verifying that the
algorithm is compatible to Ruby's OpenSSL RC4 algorithm.

Stephen Fewer c48633cff0 Merge in a rewritten windows x86 reverse_ipv6_tcp stager (The previous one seems hosed since r6744 due to new host/port offsets[1] but the shellcode blob remained the same after modification[2]) - This new one uses the block_api_call technique, is 37 bytes smaller and can handle arbitrary size stages.

HD Moore ee9a8f4f76 Adds support for the reverse_tcp_allports stager for Windows. This payload tries to connect back on all ports, one at a time, from LPORT to 65535. This is incredibly slow (depends on the default socket timeout) and requires the user to forward all TCP ports of LHOST to a single listening port in the handler. Inspired by a few user requests and this blog post: http://clinicallyawesome.com/post/196352889/blind-connect-back-through-restrictive-firewall
