Detects whether a server is vulnerable to the SSL/TLS "CCS Injection" vulnerability (CVE-2014-0224), first discovered by Masashi Kikuchi. The script is based on the ccsinjection.c code authored by Ramon de C Valle (https://gist.github.com/rcvalle/71f4b027d61a78c42607)
Retrieves a server's SSL certificate. The amount of information printed about the certificate depends on the verbosity level. With no extra verbosity, the script prints the validity period and the commonName, organizationName, stateOrProvinceName, and countryName of the subject.
Reports any private (RFC1918) IPv4 addresses found in the various fields of an SSL service's certificate. These will only be reported if the target address itself is not private. Nmap v7.30 or later is required.
Retrieves a target host's time and date from its TLS ServerHello response.
Weak ephemeral Diffie-Hellman parameter detection for SSL/TLS services.
Detects whether a server is vulnerable to the OpenSSL Heartbleed bug (CVE-2014-0160). The code is based on the Python script ssltest.py authored by Katie Stafford (firstname.lastname@example.org)
Checks whether the SSL certificate used by a host has a fingerprint that matches an included database of problematic keys.
Checks whether SSLv3 CBC ciphers are allowed (POODLE)
Determines whether the server supports obsolete and less secure SSLv2, and discovers which ciphers it supports.
Check if the Secure Socket Tunneling Protocol is supported. This is accomplished by trying to establish the HTTPS layer which is used to carry SSTP traffic as described in: - http://msdn.microsoft.com/en-us/library/cc247364.aspx
Retrieves the external IP address of a NAT:ed host using the STUN protocol.
Produces a list of IP prefixes for a given routing AS number (ASN).
Sniffs the local network for a configurable amount of time (10 seconds by default) and prints discovered addresses. If the
newtargetsscript argument is set, discovered addresses are added to the scan queue.
Inserts traceroute hops into the Nmap scanning queue. It only functions if Nmap's
--tracerouteoption is used and the
newtargetsscript argument is given.
Loads addresses from an Nmap XML output file for scanning.
Determines whether the encryption option is supported on a remote telnet server. Some systems (including FreeBSD and the krb5 telnetd available in many Linux distributions) implement this option incorrectly, leading to a remote root vulnerability. This script currently only tests whether encryption is supported, not for that particular vulnerability.
This script enumerates information from remote Microsoft Telnet services with NTLM authentication enabled.
Enumerates a TLS server's supported application-layer protocols using the ALPN protocol.

Extracts information from Ubiquiti networking devices.
Runs unit tests on all NSE libraries.
Compares the detected service on a port against the expected service for that port number (e.g. ssh on 22, http on 80) and reports deviations. The script requires that a version scan has been run in order to be able to discover what service is actually running on each port.
Attempts to extract system information from the UPnP service.
Gets system information from an Idera Uptime Infrastructure Monitor agent.
Sniffs an interface for HTTP traffic and dumps any URLs, and their originating IP address. Script output differs from other script as URLs are written to stdout directly. There is also an option to log the results to file.
