But with Windows 2000 and beyond, Microsoft has moved their NetBIOS services over to port 445 — and, perhaps not surprisingly, created an entire next-generation of even more serious security problems with that port. See the port 445 page for details. RFC's The NetBIOS over IP protocols are described in a pair of consecutive Internet RFC

Samba versions 3.6.3 and all versions previous to this are affected by a vulnerability that allows remote code execution as the "root" user from an anonymous connection. CVE-2012-1182 marks multiple heap overflow vulnerabilities located in PIDL based autogenerated code. This check script is based on PoC by ZDI marked as ZDI-CAN-1503.
NetBIOS over TCP/IP is a networking protocol that allows legacy computer applications relying on the NetBIOS to be used on modern TCP/IP networks. Enabling NetBios might help an attackers access shared directories, files and also gain sensitive information such as computer name, domain, or workgroup. Netbios and NCP vulnerabilities I have been ask by our security people to address the following issues on My Netware 6.5 servers: Null Session Share Enumeration Dec 04, 2017 · Broadband protocols, like NetBIOS over TCP/IP and LLMNR are also obsolete and used in the majority of modern networks only for compatibility reasons. At the same time, hackers have different tools that use some vulnerabilities in NetBIOS and LLMNR to capture user credentials in a local network (including NTLMv2 hashes).
