This module exploits a path traversal vulnerability in the "linuxpkgs"
action of "agent" controller of the Red Hat CloudForms Management Engine
5.1 (ManageIQ Enterprise Virtualization Manager 5.0 and earlier).
Adds support to load a dll and identify the ReflectiveLoader offset.
Adds support to inject dll into process and execute it.
Updates kitrap0d, ppr_flatten_rec, reflective_dll_inject modules and
payload modules to use above features.
Now broken into two modules, one for loading RDI DLLs off disk and
finding the loader function offset, and another for doing the process
specific stuff of loading into the target.
It's kind of a dumb reason but there are metasploit metadata parsers out
there that barf all over @names. They assume user@email.address. Should
be fixed some day.
MSF was starting to see more modules using RDI to load binaries into
remote processes, so it made sense to create a mixin which contained
the functionality that was being used in various locations.
This commit contains the new mixin, and adjustments to all the existing
exploits and modules which use RDI.
The HttpClient mixin has a peer() method, therefore these modules
should not have to make their own. Also new module writers won't
repeat the same old code again.
I had inteded to add the `WfsDelay` as Meatballs suggested, but for locl
exploits this doesn't appear to work as expected. After speaking to HDM
we've decided to leave the sleep in there and figure out the `WsfDelay`
thing later.
This also includes a slight refactor which puts the payload and the
exploit in the same chunk of allocated memory. Minor optimisation, but
worth it.
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.
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.
* Change ranking.
* Update references to comply with correct approach.
* Update messages to better describe what should happen.
* Update the Windows version regex to match XP.
* Update `check` function to use `unless`.
Thanks again @jvazquez-r7 for the feedback!
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.
Marked the SSL stuff as something that needs to be resolved in order to
fix a future bug in datastore manipulation. Also, fixed some whitespace
and exec complaints
[SeeRM #8498]
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.
