Hard loop while Conficker scanning

I have been having problems with Nmap going into a hard loop when scanning certain IP ranges for Conficker infections. After some investigation, I believe I have found the cause (and a resolution.) There is code in the smb.lua script that looks like the following: ... -- Some broken implementations of SMB don't send these variables if(smb['time'] == nil) then time = 0 end if(smb['timezone'] == nil) then timezone = 0 end if(smb['key_length'] == nil) then key_length = 0 end ... This was apparently added to handle non-conformant SMB implementations. I changed this code to look like this: ... -- Some broken implementations of SMB don't send these variables if(smb['time'] == nil) then smb['time'] = 0 end if(smb['timezone'] == nil) then smb['timezone'] = 0 end if(smb['key_length'] == nil) then smb['key_length'] = 0 end ... I think this is what the author originally intended. I can now scan networks with 'troublesome' SMB implementation without Nmap going into a loop. Was this the right fix? Whom do I tell about this? -=[ Steve ]=- _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
