NSE script uses info about known services to provide data on vulnerabilities. Note that it is already included into the standard nmap NSE library.
nmap libraries:
http
json
string
http-vulners-regex
Keep in mind that the script depends on having information about software versions, so it only works with -sV flag.
NB: Now it can actually be run without -sV flag if http-vulners-regex script is run as well.
locate where your nmap scripts are located on your system
for *nix system it might be ~/.nmap/scripts/ or $NMAPDIR
for Mac it might be /usr/local/Cellar/nmap/<version>/share/nmap/scripts/
for Windows it might be C:\Program Files (x86)\Nmap\scripts
copy the provided script (vulners.nse) into that directory
run *nmap --script-updatedb* to update the nmap script DB
Use it as straightforward as you can:
nmap -sV --script vulners [--script-args mincvss=<arg_val>] <target>
It is KISS after all.
NSE script scans HTTP responses and identifies CPEs for the mentioned software. It can therefore boost the efficiency of the main vulners script.
Or with the paths:
nmap libraries:
http
json
string
stdnse
shortport
table
locate where nmap is located on your system
for *nix system it might be ~/.nmap/ or $NMAPDIR
for Mac it might be /usr/local/Cellar/nmap/<version>/share/nmap/
for Windows it might be C:\Program Files (x86)\Nmap\
copy the provided script (http-vulners-regex.nse) into <nmap_dir>/scripts/
copy the provided json with the regexes to <nmap_dir>/nselib/data/
copy the provided txt file with the default paths to <nmap_dir>/nselib/data/
note that you can specify your own file via command line
run *nmap --script-updatedb* to update the nmap script DB
As a usual NSE script:
nmap --script http-vulners-regex.nse [--script-args paths={"/"}] <target>
This is basically the good old faithfull nmap-vulners from above with an important exception: it requires an API_KEY to work.
Moreover it specifically uses CVSS v3 score rather than v2 in its output.
You can either specify it on the CLI using the 'api_key' script argument, set it into an envirotnment variable VULNERS_API_KEY, or store it in a file readable by the user running nmap. In this case you must specify the absolute path to the file using the 'api_key_file' script argument.
As a usual NSE script:
nmap -sV --script vulners_enterprise [--script-args mincvss=<arg_val>,api_key=<api_key>,api_key_file=<absolute_path>,api_host=http://my_host.com] <target>
vulners_enterprise.mincvss Limit CVEs shown to those with this CVSS score or greater.
vulners_enterprise.api_key API token to be used in the requests
vulners_enterprise.api_key_file Absolute path to the file with a single line containing the API token
vulners_enterprise.api_host URL to vulners API without the leading slash. Defaults to https://vulners.com
