Changes fall into these categories:
1. Avoid pathological string building. Loops over x = x .. "foo" can
become very slow. Instead, use strbuf.lua, table.concat, or just one
continuous concatenation; a = x .. y .. z is one operation, better than
a = x .. y; a = a .. z
2. Use hex-escaped strings instead of string.char. I find this more
readable in many cases, and it avoids a table lookup and function call.
3. Don't duplicate code. A few libraries and scripts had re-implemented
stdnse.generate_random_string or openssl.rand_bytes.
$ sed -i 's/stdnse.print_debug("[-a-z0-9]*:\s*\([^"]*\)"/stdnse.debug1("\1"/' *.nse
$ sed -i 's/stdnse.print_debug(\([0-9]*\),\s*"[-a-z0-9]*:\s*\([^"]*\)"/stdnse.debug\1("\2"/' *.nse
Except:
o eap-info.nse
o oracle-brute.nse
Modified:
o couchdb-databases.nse
o couchdb-stats.nse
o http-open-redirect.nse
These scripts got removed from default:
dhcp-discover
dns-zone-transfer
These scripts got removed from intrusive:
dns-recursion
ftp-bounce
http-open-proxy
socks-open-proxy
Thanks to Toni for noticing these.
socket:connect(host.ip, port.number)
socket:connect(host.ip, port.number, port.protocol)
to this:
socket:connect(host, port)
connect can take host and port tables now, and the default protocol is
taken from the port table if possible.
1) I wrote a function that formats output from scripts in a consistent way. Although we haven't really come to a concensus on how it should look yet, it's easy to change when we do.
2) New script: smb-enum-groups.nse. Enumerate the local groups on a system and their membership.
discussion on nmap-dev about how best to handle these. I also updated the docs and
am about to regenerate script.db. See this thread for more info:
