Use R to connect back from a unix shell.
Notes:
We need to DRY this up - tons of copy pasta here, when we should
really be instantiating the language specific payloads and just
wrapping them with CLI execution strings.
Testing:
None, yet, just did the quick port to wrap this and push to CI
now that rex-arch #4 is in.
Initial implementation of bind and reverse TCP shells in R.
Supports IPv4 and 6, provides stateless sessions which wont change
the cwd when cd is invoked since each command invocation actually
spawns a pipe to execute that specific line's invocation.
R injections are common in academic software written in a hurry by
students or lab administrators. The language runtimes are also
commonly found adjacent to valuable data, and often used by teams
which are not directly responsible for information security.
Testing:
Local testing with netcat bind and rev handlers.
TODO:
Add the appropriate platform/language library definitions
Updated both the metasploit-payload and metasploit-payload-mettle gems
to the versions that match for the session GUID pull requests. Updated
the payload cached sizes to match the new payloads.
The Session GUID will identify active sessions, and is the beginning of
work that will allow for tracking of sessions that have come back alive
after failing or switching transports.
This module performs a privilege escaltion on mainframe systems
runing z/OS and using RACF for their security manager. A user
with any non-privileged credentials and the ability to write to
an apf authorized library can use this payload to add "root level"
privileges (e.g. SPECIAL / BPX.SUPERUSER) to their profile.
The shell does exactly the same as the previous, just made the code read much
better so as to not severely anger the gray beards and other lesser
mainframe deities. The only architectural change is the payload uses the
spawn system call vs exec - this provides for a cleaner exit in some cases.
I think PAYLOADSTR should take precedence over PAYLOADFILE. Usually,
you'll use PAYLOADFILE but might want to override with PAYLOADSTR. I
doubt this change will hurt anyone, since few people set both at once.
The payload description even says "either," so there's that.
This commit moves much of the platform-specific logic from the
reverse_http handler down into the payloads. This makes the handler
a bit more agnostic of what the payload is (which is a good thing).
There is more to do here though, and things can be improved.
Handling of datastore settings has been changed to make room for the
ability to override the datastore completely when generating the
payloads. If a datastore is given via the `opts` then this is used
instead otherwise it falls back to the settings specified in the usual
datatstore location.
Down the track, we'll have a payload that supports multiple stages, and
the datastore will be generated on the fly, along with the stage itself.
Without this work, there's no other nice way of getting datastore
settings to be contained per-stager.
The payload was missing require 'msf/core/handler/reverse_tcp', latest update pulled with msfupdate broke the startup of the framework, where you got this kind of an error:
