Problem parsing returned data that does not happen in Ruby

[darkoperator]

I'm using the library to write a automation module in PowerShell for Metasploit. The command for getting a list of sessions when received gets parsed in Ruby as:

>> rpc.call("session.list")
=> {1=>{"type"=>"meterpreter", "tunnel_local"=>"192.168.1.104:8080", "tunnel_peer"=>"192.168.1.183:1028", "via_exploit"=>"exploit/windows/smb/ms08_067_netapi", "via_payload"=>"payload/windows/meterpreter/reverse_tcp", "desc"=>"Meterpreter", "info"=>"NT AUTHORITY\\SYSTEM @ WIN2K3VMTEST", "workspace"=>"default", "session_host"=>"192.168.1.183", "session_port"=>445, "target_host"=>"192.168.1.183", "username"=>"carlos", "uuid"=>"zkzemzq5", "exploit_uuid"=>"mjqmtx7b", "routes"=>"", "platform"=>"x86/win32"}}

Now when I use msgpack.dll in both C# and PowerShell I get the following exception:

"Do not convert System.Byte (binary:0x1) MessagePackObject to MsgPack.MessagePackString."

Any clue what the error could be? I even tried it in python and it seemed to work fine with the python library. I compiled msgpack.dll using VS 2012

Would you tell me what type did you deserialize stream to? If you deserialized stream as Dictionary<String, String>, for example, deserialization will fail because first key is numeric '1'.

Looks like the library I'm using it turning it into a Dictionary :) I will inform the author of it https://github.com/brandonprry/metasploit-sharp/blob/master/metasploit-sharp/MetasploitSession.cs#L110

I see that the methods in unpacking do not include unpacking to a Hashtable so as to keep the key/value structure but offer ILits and String, what would your recommendation be in this case given the structure?

[yfakariya]

You can use any of following to get raw key/value structures: 1) MessagePackSerializer.Create<Dictionary<MessagePackObject, MessagePackObject>>().Unpack... // returns Dictionary<MessagePackObject, MessagePackObject> 2) Unpacking.UnpackDictionary(...) // returns MessagePackDictionary(IDictionary<MessagePackObject,MessagePackObject>) 3) Unpacking.UnpackObject(...).AsDictionary(); // returns MessagePackDictionary 4) Unpacker.Data.AsDictionary(); // returns MessagePackDictionary

And you can cast MessagePackObject to various primitives.

Does it answer you?
