Enhancements for SMB2 support in NMAP Script Engine

Why

The smb2 implementation that is part of NMAP lacks support for parsing NEGOTIATE_CONTEXT structures that can be used to determine hosts that might be vulnerable to CVE-2020-0796. The code in this repository adds that functionality.

Usage

The modified smb2.lua library and the modified smb2-capabilities.nse sript are intended to be used with NMAP 7.70.

Copy or symlink smb2.lua to ~/.nmap/nselib/ and use the NSE script on a host:

nmap --script=`pwd`/smb2-capabilities.nse $IP
