smb2 blank credentials issue. #933
Comments
|
Thank you for your report. Can you send a pr with a fix? If not please provide the output I need to implement it |
|
I am sorry I am not skilled enough to fix this. I am not sure what you mean with "output" other than the one I already posted. |
|
if you have a blank line in a password file, hysdra assumes blank is success, and doesn't continue looking for real passwords, so just false positive is "", remove the "" line from the password file and it finds as it should... still a bug and would be best fixes |

Using smb2 Hydra successfully discerns between valid and non valid passwords, with the exception of blank ones, in the latter always returns a false positive, even for non existing accounts. A different SPNEGO message is shown if using hydra or smbclient, which authenticates correctly. Furthermore the
-e nswitch has a bug on it's own.smbclient -L 192.168.47.1 -U "John%" -d7
