This commit contains a few changes for the ppr_flatten_rec local windows
exploit. First, the exploit binary itself:
* Updated to use the RDI submodule.
* Updated to build with VS2013.
* Updated to generate a binary called `ppr_flatten_rc.x86.dll`.
* Invocation of the exploit requires address of the payload to run.
Second, the module in MSF behaved a little strange. I expected it to create
a new session with system privs and leave the existing session alone. This
wasn't the case. It used to create an instance of notepad, migrate the
_existing_ session to it, and run the exploit from there. This behaviour
didn't seem to be consistent with other local exploits. The changes
include:
* Existing session is now left alone, only used as a proxy.
* New notepad instance has exploit reflectively loaded.
* New notepad instance has payload directly injected.
* Exploit invocation takes the payload address as a parameter.
* A wait is added as the exploit is slow to run (nature of the exploit).
* Payloads are executed on successful exploit.
This commit is the first in a series that will move all the exploits that use RDI
over to the R7 fork. The RDI source will be in a single known location and each
exploit will have to work from that location.
The kitrap0d exploit has been migrated over to use this submodule so that there's
one example of how it's done for future contributions to follow.
As per discussion on the github issue, the following changes were made:
* Project renamed from elevate to kitrap0d, implying that this is not
intended to be a generic local priv esc exploit container.
* Container DLL no longer generic, always calls the kitrap0d exploit.
* Removal of all x64 code and project configurations.
* Invocation of the exploit changed so that the address of the payload
is passed in to the exploit entry point. The exploit is now responsible
for executing the payload if the exploit is successful. This removes
the possibility of the payload getting executed when the exploit fails.
* Source moved to the appropriate CVE folder.
* Binary moved to the appropriate CVE folder.
* Little bit of source rejigging to tidy things up.
The exploit now properly injects the DLL using RDI and invokes the
exploit based on a parameter passed by the Ruby module. The elevate
code is 'generic' with a goal of possibly supporting more exploits
down the track.
New sessions are now created with the SYSTEM creds, rather than
modifying the existing session. This is now inline with how things
are done with other local modules.
* 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 version modifies the existing meterpreter session and bumps the privs
up to SYSTEM. However it's not how local exploits are supposed to work.
More work will be done to make this create a new session with the elevated
privs instead.
- 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
Convert the dx calls from build.sh to equivalent exec calls in Maven
deploy profile.
While this commit takes into account differences between Windows and *nix,
it was only tested on Windows, and the resulting binaries have not been
tested at all!
In addition, I was not able to pass individual .class file names to dx
without getting a "class name does not match path" error, so I changed it
to copy all required classes into a temp directory and call dx from there.
I also changed the cross-project paths to refer to the respective Maven
classpath, so in case you do an individual project build, the library
dependencies are taken from the Maven repository instead of taking them
from the target/ directory of the projects directly.
Include the animal-scents for Android API in this commit, so that users
who do not have Android SDK can still check meterpreter API compatibility
with Android API. Some classes, like screenshot have been excluded since
they need AWT (but they are excluded in Android Meterpreter anyway).
To regenerate the scents file, run
mvn -Dandroid.sdk.path=... -P regenerate package
Apparently Android API 3 does not know the getMTU() function, which was
added in Java 1.6, and in Android API Level 9 (Gingerbread). Therefore,
fall back to the 1.4 version that does not need this API.
Apparently, getNetworkPrefixLength can return -1, which confuses the Ruby
side. Therefore fall back to guessing the prefix in this case, as we do it
for Java <= 1.6.
Apparently, my last update came from the future. This modification
to that future update fixes an oversight preventing Armitage from
connecting to its collaboration server because it would report the
wrong application.
This update to Armitage improves its responsiveness when connected
to a team server over a high latency network. This update also adds
a publish/query/subscribe API to Cortana.
The BindTCP test contained a race condition: if the bind payload took
longer to load than the handler, it could result in a
ConnectException: Connection refused: connect
Work around this by retrying the connection up to 10 times, with 500ms
delay in between.
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
This update adds the ability to manage multiple team server instances
through one Armitage client. This update also adds nickname completion
to the event log. Several bug fixes are included too.
This update to Armitage adds the ability to assign labels to hosts
and create dynamic workspaces based on these labs. This update also
adds helpers to configure USERNAME/PASSWORD options and EXE::Custom
and EXE::Template. Several bugs were fixed as well.
Armitage on Windows requires the user to specify their MSF
install folder. This tweak checks for an MSF 4.5 environment
and updates the specified folder to make everything work.
Like magic.
This is Armitage release 01.04.13. This update fixes several bugs
and improves the user experience launching *_login modules from
Armitage. This update adds a Windows 8 icon and includes a fix to
better work with the Metasploit 1.45 installer's environment.
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 :-)
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).
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.
Downgrad JUnit version since JUnit 4 can only work with -target 1.5 or
higher class files.
Covered are Shell and Meterpreter stage, StreamForwarder, MemoryBuffer,
AESEncryption and Payload (Bind, Reverse, Spawn, AESPassword).
Check JavaPayload and Java Meterpreter against version incompatibilities
for Java 1.2, 1.3, 1.4, 1.5, and 1.6.
Note that webcam_audio_record is currently excluded from the checks, as it
uses Sun proprietary API for building the WAV file and is therefore
failing the build (and will most likely crash Meterpreter if run on a JVM
of version 1.4 or later that is not based on the Sun/Oracle JVM).
Possible workarounds (apart from either removing the module or changing it
to produce empty files when WAV creation is not supported) include
implementing the WAV file writer ourselves or providing raw PCM files
instead.
- Adds a call to mprotect(2) to the reverse and bind stagers
- Adds accurate source for some other linux shellcode, including some
comments to make it more maintainable
- Adds tools/module_payload.rb for listing all payloads for each exploit
in a greppable format. Makes it easy to find out if a payload change
causes a payload to no longer be compatible with a given exploit.
- Missing from this commit is source for reverse_ipv6_tcp
Now you can "make single_bind_tcp_shell", or the like, and build one
payload instead of the kludgy embedded shell script that always builds
all of them.
Need to do the same with BSD.
