This PR makes a small change to attempt to re-authenticate when the client receives the
STATUS_NETWORK_SESSION_EXPIREDerror. This is how Window'snet useclient responds to the error.https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-smb/6ab6ca20-b404-41fd-b91a-2ed39e3762ea
The
smb_relayMetasploit module makes it possible relay an authentication request to multiple targets, by making use of the SMB errorSTATUS_NETWORK_SESSION_EXPIRED. The relay server first tricks the client into thinking it's authentication attempt was successful, and then throws the error codeSTATUS_NETWORK_SESSION_EXPIREDwhich forces the client to re-authenticate and allows the relay server to relay to as many targets as it would like by sending that error code repeatedly.It seems like this minor detail was never implemented in ruby_smb, nor was it implemented in python's smbprotocol implementation as seen here python smb issue. This is why the
smb_relaycould never relay authentication from any client other thannet use.Testing
