When Samba is used as a domain controller, an unauthenticated attacker on the network can gain administrator access by exploiting a netlogon protocol flaw (CVE-2020-1472). Note that Samba installations are not vulnerable unless they have the smb.conf lines ‘server schannel = no’ or ‘server schannel = auto’.
| OS | Version | Architecture | Package | Version | Filename |
